WARNING: do not use Pete Kaiser's emacs function "gs-toc" alone to
|
|
re-create the table of contents here, because it will replace the
|
|
hand-edited TOC subheads with a separate subhead for each H2 in
|
|
the body of the file. Or if you do, first look at the original
|
|
TOC to see how to edit it for visual conciseness.

<h2><a name="Version3.70p1"></a>Version 3.70 patch 1 (6/24/96)</h2>
|
|
|
|
<p>
|
|
This contains a few last-minute patches before the release.
|
|
|
|
<h3><a name="V3.70p1_Procedures"></a>Procedures</h3><pre>
|
|
Comments out the color inkjet drivers in the cc-based makefile, because a
|
|
bug in Sun's cc prevents them from compiling. (cc-head.mak)
|
|
|
|
</pre><h3><a name="V3.70p1_Drivers"></a>Drivers</h3><pre>
|
|
Fixes bugs:
|
|
- The os2prn driver smashed memory. (gdevos2p.c)
|
|
- Some initialized structures weren't declared 'static'.
|
|
(gdevpdf.c, gdevpdfm.c)
|
|
- The PNG driver wouldn't compile with some older versions of the
|
|
PNG library. (gdevpng.c)
|
|
|
|
</pre>
|
|
|
|
<h2><a name="Version3.70"></a>Version 3.70 (limited) (6/23/96)</h2>
|
|
|
|
<p>
|
|
This is the candidate fileset for 4.0. Aside from one optimization
|
|
for the PDF writer, the only changes are bug fixes.
|
|
|
|
<h3><a name="V3.70_Documentation"></a>Documentation</h3><pre>
|
|
|
|
Renames all the documentation files from *.doc to *.txt, since the .doc
|
|
extension didn't give any information about the format of the file.
|
|
(readme, *.doc, *.txt)
|
|
|
|
Notes that IJG JPEG library v6[a] is now required. (jpeg.mak)
|
|
|
|
Brings ps2pdf.1 up to date. (ps2pdf.1)
|
|
|
|
Adds a new file describing Aladdin's C coding practices. (c-style.txt)
|
|
|
|
Updates the man pages to refer to version 4.0. (gs.1, pdf2ps.1, ps2ascii.1,
|
|
ps2pdf.1)
|
|
|
|
</pre><h3><a name="V3.70_Procedures"></a>Procedures</h3><pre>
|
|
|
|
Changes some file names to fit within the MS-DOS 8.3 limit. (gs.mak)
|
|
|
|
Adds the PDF writer to the remaining 32-bit configurations (Watcom, OS/2,
|
|
MSC). (watc.mak, watcwin.mak, os2.mak, msc.mak, msvcwint.mak)
|
|
|
|
Changes the -sFONTMAP= switch so it can take a list of font names, like a
|
|
search path. (use.txt)
|
|
|
|
</pre><h3><a name="V3.70_Drivers"></a>Drivers</h3><pre>
|
|
|
|
Fixes bugs:
|
|
- Signed and unsigned values were mixed inconsistently. (gdevcdj.c)
|
|
- PDF files could contain e-format floating point numbers, which the
|
|
PDF specification doesn't allow. (gdevpdfx.h, gdevpdf*.c)
|
|
- The PDF writer didn't handle glyphshow properly. (gs_pdfwr.ps)
|
|
- The PDF writer did the wrong thing with fonts whose FontMatrix had
|
|
a non-zero translation component. (gs_pdfwr.ps, gdevpdft.c)
|
|
- The stand-alone bounding box device could crash when setting
|
|
parameters. (gdevbbox.c)
|
|
- The mswinpr2 driver smashed memory. (gdevwpr2.c)
|
|
|
|
Changes the PDF writer so that if it encounters a re-encoded character, it
|
|
tries to map it to an encoded character in the standard (ISO Latin-1)
|
|
encoding rather than converting the entire string containing it to a bitmap.
|
|
This dramatically improves output file size for files with a few divergently
|
|
encoded characters, but it may cause the text in the PDF file to differ from
|
|
the text in the PostScript input. (gdevpdft.c)
|
|
|
|
Disallows BitsPerPixel=16 in the MS Windows and OS/2 drivers, since this bit
|
|
depth is not supported by Windows and would require special extra buffering.

|
|
|
|
Changes the font searching rules in the following NON-BACKWARD-COMPATIBLE
|
|
way: (gs_fonts.ps, gs_res.ps)
|
|
- -sFONTMAP=files specifies a list of files containing fontmaps;
|
|
previously, it specified only a single fontmap file.
|
|
- If -sFONTMAP= is not used, the interpreter reads the Fontmaps from
|
|
*all* directories on the search path, and does so even if FONTPATH or
|
|
GS_FONTPATH is set; previously, it read only the first Fontmap, and only if
|
|
[GS_]FONTPATH was not set.
|
|
- Fontmap(s) take precedence over [GS_]FONTPATH; previously,
|
|
[GS_]FONTPATH caused Fontmap to be ignored. (You can still force Fontmap to
|
|
be ignored with -dNOFONTMAP.)
|
|
- Earlier [GS_]FONTPATH entries take precedence over later;
|
|
previously, later entries took precedence over earlier. Note that this is
|
|
different from Fontmap: earlier Fontmaps in the search path take precedence
|
|
over later, but within a single Fontmap, later entries take precedence over
|
|
earlier (for backward compatibility).
|
|
- [GS_]FONTPATH is consulted only if there is no Fontmap entry for a
|
|
font, or no Fontmap entry leads to successful loading; previously,
|
|
[GS_]FONTPATH was always consulted at startup.
|
|
- If loading a font fails, the interpreter tries the next Fontmap
|
|
entry; previously, it fell back to font substitution.

|
|
- setcacheparams (or setting the MaxFontCache user parameter) didn't
|

actually affect the size of the character cache. (zfont.c, zmisc2.c)
|
|
- The main interpreter loop declared iref as a ref *, even though it
|
|
may only be a ref_packed *. (iref.h, interp.c)
|
|
|
|
Changes the character cache so it ignores absurd FontBBox values. Nothing

questionable output produced by PageMaker 5.0 (an Adobe product!).

well, and didn't handle off-curve points at the end of a contour properly.
|
|
(gstype42.c)
|
|
- An #include was omitted. (gsimage.c, gxclimag.c)

incorrectly. (gstype42.c)
|
|
- Type 42 fonts with an absent or incorrect FontBBox could fail to

|
produce output. (gstype42.c)
|
|
- Some header files weren't protected against double inclusion.
|
|
(gsio.h, gdebug.h)
|
|
- Decoding filters didn't "look ahead" to detect EOD, so if the last
|
|
read operation before closing the filter ended just before the EOD mark, the
|
|
EOD mark might not be absorbed. (stream.h, stream.c)
|
|
- Filling paths consisting of multiple subpaths that overlap in Y
|
|
produced slightly inaccurate output. We were unable to find a way to fix
|
|
this without making a NON-BACKWARD-COMPATIBLE change in the interface for
|
|
the recently introduced fill_trapezoid device procedure. (gxdevice.h,
|
|
gdevbbox.c, gdevddrw.c, gdevnfwd.c, gxfill.c)
|
|
- When banding, get_bits didn't detect calls with out-of-range Y
|
|
values. (gxclread.c)

|
- setcacheparams didn't actually affect the size of the character
|
|
cache. (gsfont.h, gxbcache.h, gxfcache.h, gschar.c, gsfont.c, gxbcache.c,

- The bounding box device could give bizarre results if any objects
|
|
crossed the lower edge of the page. (gdevbbox.c)
|
|
- The bounding box device could get a memory access error when

|
processing image data. (gdebbox.c)
|
|
- The bounding box device ran the default drawing algorithms even if
|
|
it had no target (performance bug only). (gdevbbox.c)
|
|
- The bounding box device computed an incorrect (too small) box for
|
|
partially clipped bitmap images. (gdevbbox.c)
|
|
- The bounding box device got confused by files that filled the
|
|
entire page with a background color. (gdevbbox.c)
|
|
- The bounding box device produced infinite-height boxes for certain
|
|
kinds of data. (gdevbbox.c)
|
|
|
|
Changes some type declarations slightly to reduce the number of 'discarding
|
|
const' compiler warnings. (gsmemory.h, gsstruct.h)
|
|
|
|
Adds the capability of clipping to the outside rather than the inside of the
|
|
clipping path. This is required for emulating an obscure feature of the
|
|
Microsoft Windows GDI. (gspath.h, gxclpath.h, gxpath.h, gxcpath.h,
|
|
gzcpath.h, gspath.c, gxacpath.c, gxclpath.c, gxclread.c, gxcpath.c.)
|
|
|
|
Makes it possible for band devices to select the underlying memory device
|
|
used to accumulate the actual bits. This is required for (at least) PCL5
|
|
emulation. This requires adding a procedure to the gx_device_printer
|
|
structure, which, for devices that initialize the structure without using
|
|
the macros in gdevprn.h or access the printer-specific procedures directly,
|
|
is a NON-BACKWARD-COMPATIBLE change. (gdevprn.h, gxclist.h, gxdevice.h,

gdevdflt.c, gdevprn.c, gxclread.c)
|
|
|
|
Speeds up handling of rotated or halftoned masked images. (gximage2.c)

Adds an output_page procedure to the bounding box device, for testing.

|
|
- x_wrap_get_bits was ridiculously slow. (It still is, but not

- An accidentally opened tiny window didn't get closed.
|
|
(gdevwdib.c)
|
|
- The name DllInit was misleading, and this procedure wasn't being
|
|
called whtn the DLL was loaded, so the DLL couldn't know the instance
|
|
handle. (gp_mswin.c)
|
|
- The code didn't recognize Win32s (vs. Windows 95) correctly.
|
|
(dwmain.cpp, gdevwdib.c, gp_mswin.h, gp_mswin.c, gsdll16.rc)
|
|
- Some compiler warnings needed fixing. (gdevwdib.c)
|
|
- gsdll16.def and gsdll32.def were different. (gsdll32.def)
|

unusable. (dwmain.cpp)
|
|
- Two obsolete files were still included in the fileset.
|

(gswin.def, gswin32.def)
|
|

|
Adds a compile-time option to the 'bit' drivers to expand 4-bit pixels to

|
|
- The driver used to use Colors as well as ProcessColorModel to
|
|
define the process color model. (devices.doc, gdevbjc.h, gdevcdj.c)

|
SVR4.0. (make.doc, ansihead.mak, cc-head.mak, gcc-head.mak, time_.h)
|
|
|
|
Changes the default Unix data installation directory from /usr/local/lib to
|
|
/usr/local/share, which seems to be favored by more recent Unix systems
|
|
(except for some Linux versions, which still use /usr/local/lib, and BSD/OS,

This release cleans up the new Windows files, mostly implements the
|
|
high-level driver API for bitmap images, and adds practical strip
|
|
(AccurateScreens) halftoning. This is the first "serious beta" fileset for

|
|
(make.doc)
|
|
- gxcindex.h still referred to "drawing color". (gxcindex.h)
|
|
- The name of the default font directory for Unix systems was
|

Moves the list of files required for installation, and some other
|
|
installation instructions, from make.doc to install.doc. (install.doc,

|
make.doc)
|
|
|
|
Adds a description of the PNGPredictor filters. (language.doc)

Documents the change in the Watcom build procedure. (make.doc)
|
|
|
|
Improves the documentation of bitmap IDs. (gxbitmap.h)
|

|
|
Adds documentation for the new strip_tile_rectangle and strip_copy_rop
|

MS-DOS shell. (int.mak)
|
|
- The configuration files weren't generated correctly when CONFIG
|
|
wasn't an empty string. (unixhead.mak)
|
|
|
|
Factors out shared DLL makefile rules into a new file. (bcwin.mak,
|
|
bcwin32.mak, dwcommon.mak)
|
|
|
|
Makes the cp and rm commands into makefile parameters, allowing automatic
|
|
generation of build scripts even in the MS-DOS and MS Windows environments
|
|
where the shell requires the CALL command for sub-scripts. (*.mak,
|
|
genconf.c)
|
|

|
Adds the PDF writer to the default Unix configurations. (ansihead.mak,

cc-head.mak, gcc-head.mak)
|
|
|

- The bit devices were missing the map_color_rgb procedure.
|
|
(gdevbit.c)
|
|
- The MS Windows driver sent a redundant message. (gdevmswn.c)
|
|
|
|
Adds a device that keeps track of the page bounding box. This device is not
|
|
included in any standard configuration. (drivers.doc, gdevbbox.h,
|
|
gsmatrix.h, gsstruct.h, gxdevice.h, gdevbbox.c, gdevnfwd.c, gsmatrix.c)
|
|
|
|
Updates the PDF writer to track the changes in the high-level driver API,
|
|
and to write out images in a reasonable way. NOTE: the current
|
|
implementation doesn't write out CIE color space parameters, so CIE-color
|
|
images won't be colored accurately. (gdevpdf.c, gdevpdfi.c)
|
|
|
|
Adds a forwarding procedure for tile_rectangle. (gxdevice.h, gdevnfwd.c)
|
|
|
|
Changes the copyright notices on the PDF writer to be the same as on the
|
|
rest of Ghostscript. (gdevpdf*.[ch])
|
|
|
|
Updates Gunther Hess's Epson Stylus Color driver from 1.21 to 1.90. (Aladdin
|
|
Enterprises takes no responsibility for this driver: if you have questions,

Works around a memory limitation in the Watcom make utility. (wmakebat.bat)
|
|
|

</pre><h3><a name="V3.68_Fonts"></a>Fonts</h3><pre>
|
|
|

Changes the standard Fontmap from using the low-quality fonts converted from

bitmaps to using high-quality fonts recently contributed by URW++.
|
|
(Fontmap, Fontmap.GS)
|
|
|
|
</pre><h3><a name="V3.68_Interpreter"></a>Interpreter</h3><pre>
|
|
|
|
Fixes bugs:
|
|
- A macro containing an if-else, and a macro generating a compound
|
|
statement, could cause incorrect grouping of 'if' statements. (files.h,
|
|
ostack.h)
|
|
- .setrasterop didn't pop its operand. (zrop.c)
|
|
- A rounding inaccuracy could cause bounding box rangecheck errors.
|
|
(gsdps1.c)
|
|
- CIE-based images in PDF files didn't work. (gs_pdf.ps)
|
|
- The page parameter .MediaSize didn't get updated when PageSize was
|
|
set. (This is just the most recent manifestation of the setpagedevice
|
|
morass.) (gs_setpd.ps)
|
|
- %lineedit and %statementedit were limited to 160 characters.
|
|
(zfileio.c, ziodev.c)
|
|
- Compiled initialization files didn't work properly. (geninit.c,
|
|
gs_l2img.ps)
|
|
- Attempting to parse a command line with argc = 0 caused a crash.
|
|
(imainarg.c)
|
|
|
|
Renames some files to allow separating the non-DLL 'main' procedure into a
|
|
separate file, and to make the file naming more consistent:
|
|
gs.c (except for 'main') => imainarg.c
|
|
gsmain.c => imain.c
|
|
gs.c now consists only of 'main'. The name gs.c is still inconsistent (it
|
|
should be i- something), but at least it's consistent with the name of the
|
|
executable. (*.mak, imain.h, iminst.h, imainarg.h, gs.c, gsmain.c, imain.c,
|
|
imainarg.c)
|
|
|
|
Adds PNGPredictorEncode/Decode filters, and increases the size of filterdict
|
|
slightly to make room for them. (iinit.c, zfpngp.c)
|
|
|
|
Makes zwrite external, per a customer request. (opextern.h, zfileio.c)
|
|
|
|
Updates clients to work with the new API-based bitmap imaging calls.
|
|
(iimage.h, zcolor1.c, zimage2.c, zpaint.c)
|
|
|
|
Updates clients for the split in gscspace.h. (zcie.c, zcolor1.c, zcolor2.c,
|
|
zcsindex.c, zcssepr.c, zimage2.c, zpaint.c, zpcolor.c)
|
|
|
|
Updates clients for strip-based halftones. (zpcolor.c)
|
|
|
|
Updates the initialization code to pass the correct (system) allocator to
|
|
the library initialization. (imain.c)
|
|
|
|
</pre><h3><a name="V3.68_Streams"></a>Streams</h3><pre>
|
|
|
|
Fixes bugs:
|
|
- If a filter reached EOD exactly at the end of reading data for
|
|
certain operations, it didn't get closed automatically. (stream.c)
|
|
- The LZW-compatible encoding filter reset procedure had an
|
|
incorrect return type. (slzwce.c)
|
|
|
|
Changes the ASCIIHexEncode filter to insert \ns in fewer places, to be
|
|
somewhat more compatible with the Adobe implementation. (sstring.c)
|
|
|
|
Adds PNGPredictorEncode/Decode filters that implement the pixel prediction
|
|
algorithms in the PNG specification. (We'd like to use the code in the PNG
|
|
library, but it's too deeply embedded in the rest of the PNG machinery, and
|
|
it also doesn't provide for suspendable I/O.) (spngpx.h, spngp.c)
|
|
|
|
</pre><h3><a name="V3.68_Library"></a>Library</h3><pre>
|
|
|
|
Fixes bugs:
|
|
- A test for pure color was backwards, causing garbage output or
|
|
possible address or floating point exceptions. (gxclpath.c)
|
|
- A macro containing an if-else could cause incorrect grouping of
|
|
'if' statements. (gsrefct.h)
|
|
- The default implementation of RasterOp didn't handle the device
|
|
depth correctly. (gdevmrop.c)
|
|
- The memory device implementation of RasterOp truncated 24-bit
|
|
constant source or texture values to 8 bits. (gdevmrop.c)
|
|
- A typo caused the garbage collector to miss an internal buffer
|
|
used when rendering images. (gximage.h)
|
|
- gs_debug_out was only defined if DEBUG was set. (gdebug.h)
|
|
- The raster of horizontally replicated tiles was incorrect.
|
|
(gxht.c)
|
|
- A data type might not be declared, causing a compilation error.
|
|
(gscoord.h)
|
|
- Empty TrueType glyphs weren't handled properly. (gstype42.c)
|
|
- Fonts with a build procedure written in C could cause an invalid
|
|
memory access. (gschar.c)
|
|
- The initial point of a band list path sometimes didn't get
|
|
written, causing excess or missing filled regions. (gxclpath.c)
|
|
- Characters between 49 and 56 bits wide were rendered incorrectly
|
|
when banding. (gxclbits.c)
|
|
|
|
Renames gsimage*.c as gximage*.c, to reflect more accurately the position of
|
|
these files in the architecture. (gsimage*.c, gximage*.c)
|
|
|
|
Fully implements the high-level bitmap image calls in the driver API. This
|
|
includes some driver API changes; however, this part of the API was clearly
|
|
documented as not stable enough to rely on. (gxdevice.h, gximage.h,
|
|
gdevbbox.c, gdevddrw.c, gdevnfwd.c, gsimage.c, gximage*.c)
|
|
|
|
Splits the color space header into client and implementation, as with many
|
|
others. (gscspace.h, gxcspace.h, gximage.h, gscie.c, gscolor.c, gscolor1.c,
|
|
gscolor2.c, gscsepr.c, gsimage.c, gspcolor.c, gsstate.c, gxcmap.c,
|
|
gxpcmap.c)
|
|
|
|
Extends band lists to handle high-level images. NOTE: This facility is
|
|
patched out because there is not yet a way to pass the necessary color
|
|
rendering information through the band list. (gxcldev.h, gxclist.h,
|
|
gxclpath.h, gxclimag.c, gxclist.c, gxclpath.c, gxclread.c)
|
|
|
|
Implements fixed2float and float2fixed more efficiently on machines with
|
|
slow floating point. (gxfixed.h, gscoord.c, gsmisc.c)
|
|
|
|
Makes one further NON-BACKWARD-COMPATIBLE change in the existing
|
|
higher-level driver procedures (fill_path, stroke_path, fill_mask): we make
|
|
the imager state pointer an explicit argument, rather than a member of the
|
|
gx_fill/stroke_params structure. We now consider the specification of these
|
|
procedures stable, and have removed the "subject to change" notice from the
|
|
documentation. (gxdevice.h, gxpaint.h, gdevbbox.c, gdevnfwd.c, gxacpath.c,
|
|
gxclpath.c, gxclread.c, gxfill.c, gxpaint.c, gxstroke.c)
|
|
|
|
Extends halftone bitmaps to include "strip" and "shift" information,
|
|
allowing halftone cells with arbitrary angles to be stored in space
|
|
proportional to the number of bits in the cell rather than the square of the
|
|
number of bits. This requires adding new (optional) strip_tile_rectangle
|
|
and strip_copy_rop driver procedures that are like tile_rectangle and
|
|
copy_rop respectively but accept a strip bitmap rather than an ordinary
|
|
tile; these procedures supersede tile_rectangle and copy_rop (although these
|
|
also remain, defined in terms of the new ones). This also requires making
|
|
small but NON-BACKWARD-COMPATIBLE changes in several internal interfaces.

Adds "no join" as a line join type. NOTE: this is not actually implemented

yet. (gslparam.h)
|
|
|
|
Changes the initialization code so that it passes the system allocator as an
|

argument to module initialization procedures. While this is theoretically a

|
NON-BACKWARD-COMPATIBLE change, module initialization procedures are not
|
|
documented and presumably are not used by any code outside the

implementation. (gscdefs.h, gconf.c, gdevmrop.c, gsinit.c, gxclimag.c,
|
|
gxclpath.c)
|
|
|
|
Splits up gs_lib_init into two procedures, allowing specification of a
|
|
different default allocator for the library. (gslib.h, gsinit.c)
|
|
|
|
Adds a resize_object operation to the allocator API. (gsmemory.h,

<h2><a name="Version3.67"></a>Version 3.67 (limited) (4/12/96)</h2>
|
|
|
|
<p>
|
|
This release restructures the MS Windows and OS/2 code to be primarily DLL-
|
|
rather than EXE-based. See under Platforms below for more news. This
|
|
release was put out in a hurry in order to get the new DLL code into
|
|
testers' hands; it has more rough edges than usual.

<h3><a name="V3.67_Documentation"></a>Documentation</h3><pre>
|
|
Fixes bugs:
|
|
- A definition & use comment was incorrect. (scanchar.h)
|
|
- William Bader's e-mail address was wrong. (README)
|
|
|
|
Adds documentation for the new begin_image, image_data, and end_image
|
|
procedures. THIS INTERFACE IS STILL SUBJECT TO CHANGE. (drivers.doc)
|
|
|
|
</pre><h3><a name="V3.67_Procedures"></a>Procedures</h3><pre>
|
|
|
|
Renames all the *core.dev modules as *lib.dev. (int.mak, *lib.mak, vms.mak,
|
|
gdevmrop.c)
|
|
|
|
Updates all the remaining makefiles to IJG JPEG version 6a. (*.mak)
|
|
|
|
Moves the configuration parameter definitions from gconf.c to a new file
|

</pre><h3><a name="V3.67_Platforms"></a>Platforms</h3><pre>
|
|
|
|
Restructures the MS Windows and OS/2 code to be primarily DLL- rather than
|
|
EXE-based. This involves two minor NON-BACKWARD-COMPATIBLE changes to the DLL
|
|
interface, documented near the end of dll.doc:
|
|
|
|
- Adding argv and argc as arguments to gsdll_init.
|
|
|
|
- Adding a new message type, GSDLL_POLL, to the callback procedure.
|
|

|
|
|
|
Adds the BMP drivers to the Watcom platform. (watc.mak)
|
|
|
|
</pre><h3><a name="V3.67_Interpreter"></a>Interpreter</h3><pre>
|
|
|
|
Fixes bugs:
|
|
- gs.c assumed the presence of stdio. (gs.c)
|
|
|
|
Defines a new API entry point that is the equivalent of command line
|
|
invocation. (imain.h, imainarg.h, gs.c)
|
|
|
|
Changes clients to conform to the changes in gsimage.h. (zimage2.c,
|
|
zpaint.c)
|
|
|
|
Speeds up the search operator slightly. (zstring.c)
|
|
|
|
</pre><h3><a name="V3.67_Interpreter_PDF"></a>Interpreter (PDF)</h3><pre>
|
|
|
|
Fixes bugs:
|
|
- If the PDF interpreter was present, running a PostScript file
|
|
didn't close the file properly if it caused an error. (pdf_main.ps)
|
|
|
|
Speeds up embedded font loading by making an internal buffer bigger.
|
|
(pdf_font.ps)
|
|
|
|
</pre><h3><a name="V3.67_Library"></a>Library</h3><pre>
|
|
|
|
Fixes bugs:
|
|
- There could be some non-zero garbage between the width and the
|
|
next multiple of bitmap_align_mod for copy_alpha. (The driver API
|
|
specification explicitly allows this, but it upset one customer.)
|
|
(gxccman.c)
|
|
- Nibble-swapped alpha values could be displaced in memory by one
|
|
pixel, damaging the output. (gdevabuf.c)
|
|
|
|
Makes further changes towards adding high-level bitmap image calls to the
|
|
driver API. This includes the following minor NON-BACKWARD-COMPATIBLE
|
|
changes to the interface defined in gsimage.h:
|
|
|
|
- changing MultipleDataSources from a member of the gs_image_t
|
|
structure to an argument of gs_image_init;
|
|
|
|
- changing the default image parameter values from constant
|
|
structures to procedures that initialize the structure.
|
|
|
|
As far as we know, this doesn't affect any existing client code.
|
|
(gsimage.h, gsiparam.h, gxdevice.h, gdevddrw.c, gdevnfwd.c, gsimage.c,
|
|
gspcolor.c, gxccache.c)
|
|
|
|
Removes an unnecessary level of call for path filling. (gxpaint.h,
|
|
gxfill.c, gxpaint.c)

<h2><a name="Version3.66"></a>Version 3.66 (limited) (4/8/96)</h2>
|
|
|
|
<p>
|
|
This release adds support for TrueType fonts and Type 42 (encapsulated
|
|
TrueType) PostScript fonts. The MS Windows driver now interacts properly
|
|
with the garbage collector. This release also includes a new, high-quality
|
|
set of free fonts.

<h3><a name="V3.66_Documentation"></a>Documentation</h3><pre>
|
|
Fixes bugs:
|
|
- The list of generic makefiles had gotten out of date. (make.doc)
|
|
|
|
Adds a mention of the bmv program, created by a user and available under the
|
|
GPL. (README)
|
|
|
|
Notes that a bug in gcc 2.7.x prevents these versions from compiling
|
|
Ghostscript. (make.doc)
|
|
|
|
Clarifies the meaning of "inverted" masks. (gsimage.h)
|
|
|
|
Improves the documentation of the stack sizing parameters. (interp.c)
|
|
|
|
Improves the documentation of the copy_rop driver procedure.
|
|
(drivers.doc)
|
|
|
|
Notes that all subclasses of gx_device must explicitly include the
|
|
device_finalize finalization procedure. (gxdevice.h)
|
|
|
|
Updates the documentation of the high-level driver API to reflect the change
|
|
in gx_drawing_color, and the addition of the new polygon and image drawing
|
|
procedures. (drivers.doc)
|
|
|
|
Updates the documentation for building zlib and libpng. (make.doc)
|
|
|

- The environment space overflowed on some inferior Unix systems.
|
|
(unixtail.mak)
|
|
|
|
Adds a ttfont.dev "feature" for including the TrueType interpreter and the
|
|
ability to handle Type 42 fonts. A new procedure, .loadttfont, allows
|
|
loading a TrueType font directly (by converting it to a Type 42 on the fly).
|
|
(gs.mak, int.mak, lib.mak)
|
|
|
|
Updates the makefiles and procedures to libpng 0.88 and zlib 1.0.

(pdf_2ps.ps)
|
|
|
|
Removes some unnecessary and error-inviting code from pdf2dsc. (pdf2dsc.ps)
|
|
|
|
Updates lines.ps to test the new stroke code more fully. (lines.ps)
|
|

|
|
</pre><h3><a name="V3.66_Drivers"></a>Drivers</h3><pre>

Fixes bugs:
|
|
- A routine was incorrectly declared "private". (I wish gcc caught
|
|
this!) (gdevpdf.c)
|
|
- A 'const' was omitted in a parameter list. (gdevpdfp.c)
|
|
- Some imported procedures didn't have prototypes declared.
|
|
(gdevpdft.c)
|
|
- The ProcSet list for PDF files didn't include Text when it was
|
|
needed. (gdevpdfx.h, gdevpdf.c, gdevpdft.c)
|
|
- Text in PDF output ignored the color setting. (gs_pdfwr.ps,
|
|
gdevpdft.c)
|
|
- Text in PDF output could be positioned incorrectly. (gdevpdft.c)
|
|
- pdfmarks could produce an error when producing PDF output.
|
|
(gs_pdfwr.ps)
|
|
|
|
Slightly improves the text output of the PDF writer. (gs_pdfwr.ps,
|
|
gdevpdft.c)
|
|
|
|
Defines driver procedures for filling trapezoids (with the parallel edges
|
|
parallel to a coordinate axis), parallelograms (with arbitrary orientation),
|
|
triangles (ditto), and minimum-width lines (ditto). (Note that the last of
|
|
these obsoletes the former draw_line procedure.) (gdevmem.h, gdevprn.h,

|
|
gxdraw.c (deleted), gxfill.c, gxpcmap.c, gxstroke.c)
|
|
|
|
Adds "sketched" driver procedures for high-level bitmap / pixmap image
|
|
drawing. In this release, the argument lists are incomplete, and the
|
|
procedures are stubs: don't try to use them! [see previous entry]
|
|
|
|
Changes the screen update strategy for the X Windows driver from a
|
|
compile-time option to a settable run-time variable. (gdevx.c)
|
|
|
|
Patches around a problem with libpng 0.88 that can't be fixed without

Fixes bugs:
|
|
- The Type 1 font interpreter sometimes set the flatness too large.
|
|
(gstype1.c)
|
|
- Fonts defined by definefont could never be garbage collected.
|
|
(gsstruct.h, gxfcache.h, gxfont.h, gxfont0.h, gxfont1.h, gsfont.c,
|
|
gsfont0.c)
|
|
- Type 0 fonts weren't garbage collected properly. (gsfont0.c)
|
|
- Compiled fonts caused a compilation error (bug introduced in
|
|
3.65). (ifont.h)
|
|
- If a Type 1 font used hint replacement, hints could be applied
|
|
more than once, distorting the character shape. (gxtype1.h, gxhint3.c)
|
|
- Oversampling wasn't applied to large enough characters.
|
|
(gschar.c)
|
|
|
|
</pre><h3><a name="V3.66_Interpreter"></a>Interpreter</h3><pre>
|
|
|
|
Fixes bugs:
|
|
- The scanner accepted /[, /], /<<, and />> as literal names (and
|
|
similarly for //). It isn't obvious from the Red Book, but the Adobe
|
|
implementations don't accept these. What a nuisance! (gs_btokn.ps,
|
|
gs_init.ps, pdf_2ps.ps, pdf_base.ps, pdf_main.ps, iscan.c)
|
|
- A spurious stackoverflow could occur under unusual conditions.
|
|
(istack.c)
|
|
- The values of OrigFont and ScaleMatrix in scaled fonts reflected
|
|
only the most recent scaling operation, not the original font and the
|
|
combined scaling operation. (zfont.c)
|
|
- The default size of systemdict had become slightly too small.
|
|
(iinit.c)
|
|
- Type 1 characters defined by PostScript procedures were called
|
|
incorrectly. (zcharout.c)
|
|
|
|
Removes the papersize operator from statusdict, since it is not documented
|
|
anywhere in the Adobe literature and didn't interact properly with the
|
|
various ways of setting the page size. (gs_statd.ps)
|
|
|
|
Changes the one client of sskip to match the changed API. (zpaint.c)
|
|
|
|
Changes clients to reflect the creation of sstring.h. (iscan.h, zfilter.c)
|
|
|
|
Adds PSStringEncode as an accessible filter. (zfilter.c)
|
|
|
|
Adds support for TrueType and Type 42 fonts. (gs_fonts.ps, gs_ttf.ps,
|
|
gs_typ42.ps, bfont.h, icharout.h, ifont.h, zchar1.c, zchar42.c, zcharout.c,

</pre><h3><a name="V3.66_Interpreter_PDF"></a>Interpreter (PDF)</h3><pre>
|
|
|
|
Fixes bugs:
|
|
- Clients who called pdfopen/close rather than runpdf could get an
|
|
error (PSLevel1 undefined). (pdf_main.ps)
|
|
- Some masked images were displayed with black and white inverted.
|
|
(gs_pdf.ps)
|
|
- In Level 1 output produced by pdf2ps, images caused a syntaxerror.
|
|
(gs_pdf.ps)
|
|
- If a PDF file had multiple xref sections and later sections added
|
|
new objects, an error occurred. (pdf_main.ps)
|
|
- Some very old Level 1 interpreters couldn't deal with a file
|
|
object embedded in a procedure. (gs_pdf.ps)
|
|
|
|
</pre><h3><a name="V3.66_Streams"></a>Streams</h3><pre>
|
|
|
|
Fixes bugs:
|
|
- The PSStringEncode filter didn't always produce printable 7-bit
|
|
output. (sstring.c)
|
|
- The CCITTFaxDecode filter didn't implement DamagedRowsBeforeError.
|
|
(scfx.h, scfd.c)
|
|
- Interpolated images displayed nothing if the data stream ended
|
|
before the image height was reached. (siscale.h, gsimage5.c, siscale.c)
|
|
|
|
Changes the sskip stream procedure so that it takes an additional argument
|
|
where it returns the actual number of bytes skipped. THIS IS A
|
|
NON-BACKWARD-COMPATIBLE CHANGE in the API. However, as far as we know,
|
|
there are no external clients of this procedure. (stream.h, stream.c)
|
|
|
|
Splits up sfilter.h so that the headers correspond more directly with the
|
|
implementations. (sfilter.h, sstring.h, sstring.c)
|
|
|
|
</pre><h3><a name="V3.66_Library"></a>Library</h3><pre>
|
|
|
|
Fixes bugs:
|
|
- The default device in the library configuration was device 1, not
|
|
device 0. (bclib.mak, ugcclib.mak, watclib.mak, gslib.c)
|
|
- Patterns could be rendered with small gaps between them.
|
|
(gspcolor.c)
|
|
- Large characters could render inaccurately because of a numerical
|
|
boundary condition. (gxpcopy.c)
|
|
- The show_gstate pointer in the graphics state was not managed
|
|
properly, possibly leading to dangling pointers or GC errors. (gsstate.c)
|
|
- Bitmaps could get shifted to the left if ALPHA_LSB_FIRST was
|
|
selected (bug introduced in 3.53). (gsbitops.c)
|
|
- The garbage collector could move devices in memory, causing
|
|
problems with command list devices. (gxdevice.h, gsdevice.c)
|
|
|
|
Continues restructuring the image handling code in preparation for adding a
|
|
high-level driver operation. (gsimage[12345].c)
|
|
|
|
Starts to implement passing color mapping information (transfer function,
|
|
black generation, undercolor removal, CRD, halftoning) in the band list.
|
|
(gxfmap.h, gscolor.c, gscolor1.c, gsht1.c, gsstate.c)
|
|
|
|
Speeds up the path filling code a little more. (gxdraw.c)
|
|
|
|
Removes the workaround for the gcc 2.7.0/1/2 optimizer bug, since this
|
|
turned out to cause more trouble than it was worth. (stdpre.h)
|
|
|
|
Speeds up stroking dramatically for the case of butt or square caps, bevel
|
|
or beveled miter joins, and no fill adjustment, by filling parallelograms
|
|
and triangles directly rather than constructing and filling paths. This is
|
|
an important common case for CAD drawings. (gxdraw.h, gxdraw.c, gxstroke.c)
|
|
|
|
Adds support for TrueType and Type 42 fonts. (gxfont.h, gxfont42.h,
|
|
gstype42.c)
|
|
|
|
Extends the memory manager to allow allocating objects that the garbage
|
|
collector won't move. THIS IS A NON-BACKWARD-COMPATIBLE CHANGE for
|
|
implementors of memory managers, but clients aren't supposed to have any of
|
|
these. (gsmemory.h, gsmemory.c, gsalloc.c)
|
|
|
|
Makes dynamically created instances of registered devices immovable.
|
|
(gsdevice.c)
|
|
|
|
Unifies gx_drawing_color with (makes it equivalent to) gx_device_color.
|
|
THIS IS A NON-BACKWARD-COMPATIBLE CHANGE for implementors of the
|
|
higher-level driver procedures (fill_path, stroke_path, fill_mask). We
|
|
regret that this was necessary, but the documentation in drivers.doc does
|
|
warn the reader: "DO NOT ASSUME THESE OPERATIONS WILL REMAIN UNCHANGED IN
|
|
FUTURE RELEASES." These three procedures, at least, should now be stable.

|
|
|
|
Fixes bugs:
|
|
- Some compilers require an extra #include to define structures even
|
|
if they are only referenced by pointers. (int.mak, gdevpdf.c, gdevpdfp.c)
|
|
- A procedure name was duplicated. (gdevpdfi.c)
|
|
- A pdfmark between a gsave and a grestore could cause a
|
|
rangecheck error. (gdevpdfp.c)
|
|
- A pdfmark between a gsave and a grestore could cause the
|
|
grestore to do an inappropriate initgraphics. (gs_pdfwr.ps)
|
|
- The pdfwrite driver could reinitialize the output file
|
|
unpredictably. (gdevpdfp.c)
|
|
- The PCX drivers didn't clear padding bytes at the ends of scan
|
|
lines. (gdevpcx.c)
|
|
- The PCX drivers didn't set the "version" field correctly (this was
|
|
OK in 2.6.1, bug introduced sometime since then). (gdevpcx.c)
|
|
- Whoever last touched the color inkjet drivers completely broke the
|
|
handling of the BitsPerPixel parameter, again. We were able to half-fix it,
|
|
but the code is impossible to understand, let alone modify safely.
|
|
(gdevcdj.c)
|
|
- Anti-aliased characters didn't work with banding. (gxclpath.c)
|
|
- The PGM/PPM drivers didn't recognize black-and-white pages for
|
|
optimization to PBM, only gray or colored. (gdevpbm.c)
|
|
- The color inkjet drivers initialized the params_size field of the
|
|
static instance incorrectly, resulting in garbage in the last few structure
|
|
members when instances were copied. (gdevcdj.c)
|
|
- The 24-bit PCX driver didn't pad each scan line to an even number
|
|
of bytes. (gdevpcx.c)
|
|
- The svga16 driver initialized its procedures incorrectly.
|
|
(gdevpcfb.c)
|
|
|
|
Adds text writing capability to the PDF writer. In its present form, this
|
|
is a very bad hack: it only works for the 14 built-in fonts with their
|
|
standard encodings. (gdevpdfx.h, gdevpdf.c, gdevpdfp.c, gdevpdft.c)
|
|
|
|
Adds garbage collection and finalization for device instances (gscdefs.h,
|
|
gsdevice.h, gxdevice.h, gconf.c, gdevmrop.c, gsdevice.c, gslib.c, gsmain.c).
|
|
(See the "Driver instance allocation" section of drivers.doc for more
|
|
details about what is required to make this work.)
|
|
|
|
- When an open device is freed (explicitly, by garbage collection,
|
|
or by 'restore'), if the device was allocated dynamically by Ghostscript's
|
|
standard allocator, the device's close procedure will be called. THIS IS A
|
|
NON-BACKWARD-COMPATIBLE CHANGE for dynamically created devices, which
|
|
formerly were not closed automatically, even when Ghostscript exited.
|
|
|
|
- Device instances allocated in GC-able space will be traced
|
|
like other objects, assuming they have proper structure descriptors.
|
|
|
|
Provides a (very slow but correct) default implementation of copy_alpha.
|
|
(gxcindex.h, gdevdflt.c, gsimage4.c)
|
|
|
|
Removes the implementation of copy_alpha in gdevpbm.c, since this is now
|
|
implemented (more efficiently) in gdevm24.c. (gdevpbm.c)
|
|
|
|
Adds TextAlphaBits and GraphicsAlphaBits as readable parameters for all
|
|
devices. (gsdparam.c, gdevpbm.c, gdevsvga.c)
|
|
|
|
</pre><h3><a name="V3.65_Platforms"></a>Platforms</h3><pre>
|
|
|
|
Fixes bugs:
|
|
- There were some attempts to coerce long to short pointers
|
|
on segmented platforms. (gsdparam.c, gstype1.c)
|
|
- The stack could overflow on the 16-bit MS Windows platform.
|
|
(gxfill.c, gxclread.c)
|
|
- The DLL callback parameter for window resize events was computed
|
|
incorrectly on 16-bit systems. (gdevwdib.c)
|
|
- A file included gxdevice.h unnecessarily. (bcwin.mak,
|
|
bcwin32.mak, msvcwint.mak, gp_mswin.c)
|
|
|
|
</pre><h3><a name="V3.65_Interpreter"></a>Interpreter</h3><pre>
|
|
|
|
Fixes bugs:
|
|
- Storing into a read-only dictionary with def or store was
|
|
allowed. (dstack.h)
|
|
- If the interpreter allocated extra space for a dictionary
|
|
to round its storage size up to a power of 2, it was possible for
|
|
length to exceed maxlength. (idict.c, iinit.c)
|
|
- The if and ifelse operators didn't check that their
|
|
'procedure' arguments were actually procedures. (interp.c, zcontrol.c)
|
|
- The undef operator was defined even in Level 1
|
|
configurations. (We need this capability for all configurations, so
|
|
we always define .undef.) (zdict.c, gs_*.ps, pdf_*.ps)
|
|
- In Level 1 configurations, copying a dictionary should copy the
|
|
access attributes, but it didn't. We have to work around this
|
|
compatibility quirk in a lot of places. (gs_cidfn.ps, gs_cmap.ps,
|
|
gs_dps1.ps, gs_fonts.ps, gs_init.ps, gs_l2img.ps, gs_lev2.ps, gs_pdf.ps,
|
|
gs_pfile.ps, gs_res.ps, gs_setpd.ps, gs_type1.ps, zdict.c)
|
|
- DSC comments that crossed a buffer boundary didn't call the
|
|
scan_dsc_proc. (iscan.c)
|
|
- "statusdict /setpage get exec" caused an error. (gs_statd.ps)
|
|
- The default size of systemdict had become slightly too small.
|
|
(iinit.c)
|
|
- Doing a showpage or copypage would cause the equivalent of a
|
|
setpagedevice at the next restore or grestore. We aren't entirely sure that
|
|
the fix we made doesn't have bad side-effects. (gs_setpd.ps)
|
|
- Not all filters accepted (and ignored) an optional dictionary
|
|
parameter on the stack. (ifilter.h, zfbcp.c, zfdecode.c, zfilter.c,
|
|
zfilterx.c, zfzlib.c, zmisc1.c)
|
|
- The PixelDifference filters required a Columns parameter, rather
|
|
than defaulting it to 1. (spdiffx.h, zfdecode.c)
|
|
- Contrary to the NEWS entry for release 3.60, the LZW filters did
|
|
not implement pixel differencing. (zfdecode.c, zfilter2.c)
|
|
- readstring with a 0-length string didn't signal a rangecheck.
|
|
This doesn't make a lot of sense to me, but it's what the Adobe
|
|
documentation specifies. Unfortunately, we have to work around this in a
|
|
number of places that assumed the sensible definition (return () true
|
|
without reading anything). (gs_l2img.ps, pdf_font.ps, zfileio.c)
|
|
- Encoded number strings didn't work (bug introduced in 3.64).
|
|
(ibnum.c)
|
|
- The allocator could produce spurious "free large 0x...... chunk
|
|
not found" messages. (These didn't cause any harm, but they were
|
|
disturbing.) (gsalloc.c)
|
|
|
|
Changes the default transfer function for high-resolution devices so
|
|
that it is the identity function if the device is continuous-tone.
|
|
(gs_init.ps)
|
|
|
|
Undoes the "subversion" of zgetdevice noted in release 3.61, since it
|
|
is now possible to copy devices safely. (zdevice.c)
|
|
|
|
Changes the implementation of the garbage collector and restore so that
|
|
object finalization code may safely free objects. (igc.c, isave.c)
|
|
|
|
Reimplements essentially all of Type 1 BuildChar in C. (gs_init.ps,
|
|
gs_type0.ps (deleted), gs_type1.ps, ifont.h, zchar.c, zchar1.c, zfont.c)
|
|
|
|
Reimplements DISKFONTS as a separate feature (diskfont.dev), and changes it
|
|
to use Type 4 fonts rather than special machinery. Currently this feature
|
|
is included only in the makefiles for 16-bit architectures. (bc.mak,
|
|
bcwin.mak, int.mak, tc.mak, gs_diskf.ps, gs_fonts.ps, gs_type1.ps)
|
|
|
|
Converts the library search path from a list of strings to a (PostScript)
|
|
array of strings, one string per directory. (iminst.h, main.h, gs.c,
|
|
gsmain.c, zfile.c)
|
|
|
|
Adds a hook procedure scan_comment_proc for processing all comments,
|
|
similar to scan_dsc_proc. If both are set, scan_comment_proc is used only
|
|
for non-DSC comments. (iscan.h, iscan.c)
|
|
|
|
</pre><h3><a name="V3.65_Interpreter_PDF"></a>Interpreter (PDF)</h3><pre>
|
|
|
|
Fixes bugs:
|
|
- Encrypted PDF files produced a random error (usually ioerror in
|
|
--token--) rather than a meaningful message. (pdf_main.ps)
|
|
- Color space setting didn't work. (gs_pdf.ps)
|
|
- The algorithm for skipping a possible blank line following the
|
|
'stream' keyword wasn't robust enough. (We aren't sure the new algorithm is
|
|
exactly right, either.) (pdf_base.ps)
|
|
|
|
Gets rid of the special handling of the LZW decoding filter, since the
|
|
filter itself now handles the Predictor facility. (pdf_base.ps)
|
|
|
|
</pre><h3><a name="V3.65_Streams"></a>Streams</h3><pre>
|
|
|
|
Fixes bugs:
|
|
- Configurations with LZW encoding but not decoding had an
|
|
undefined reference. (lib.mak, slzwc.c, slzwd.c)
|
|
- The LZW-compatible encoder didn't provide a 'reset' procedure.
|
|
(slzwce.c)
|
|
- The PixelDifference filters didn't work for most parameter
|
|
combinations in which each pixel took up more than 1 byte. (spdiff.c)
|
|
- Temporary write streams could cause an infinite loop. (We only
|
|
need such streams for the Predictor = 2 case of LZWEncode: this is why the
|
|
bug never showed up before.) (stream.c)
|
|
|
|
Adds an optional reinitialization procedure to the stream template. Note
|
|
that this is not the same as the PostScript 'reset' operation or the stream
|
|
resetting operation invoked by sreset: the reinit procedure in the template
|
|
reinitializes any internal state of the encoder or decoder without affecting
|
|
buffered data. (scommon.h, strimpl.h, sbcp.c, sbhc.c, slzwce.c, slzwd.c,
|
|
slzwe.c, smtf.c, spdiff.c, srle.c) ****** NOT DONE YET: sbwbs.c, szlibd.c,
|
|
szlibe.c
|
|
|
|
Adds a decoding stream for the run-length compression used in PCX.

</pre><h3><a name="V3.65_Library"></a>Library</h3><pre>
|
|
|
|
Fixes bugs:
|
|
- A recent edit introduced an extraneous right parenthesis.
|
|
(gpcheck.h)
|
|
- A minor nit in a macro could cause incorrect grouping of 'if'
|
|
statements under implausible conditions. (gsmdebug.h)
|
|
- The first data plane buffer of an image enumerator didn't get
|
|
marked during garbage collection. (gsimage.c)
|
|
- The Watcom C compiler required splitting up a declaration.
|
|
(gxcmap.h)
|
|
- The extern declarations for the tables in gconf.c weren't gathered
|
|
together in one place. (gscdefs.h, gxiodev.h, gconf.c, gsdevice.c, gslib.c,
|
|
gsinit.c, gsiodev.c)
|
|
- charpath and show produced different output. We fixed this by
|
|
undoing a "bug fix", introduced in version 2.9, which suppressed hinting and
|
|
coordinate rounding for charpath; we aren't sure this won't cause some
|
|
obscure problems to reappear. (gstype1.c)
|
|
- Clipping with a rectangle usually created a 3-rectangle clipping
|
|
list, slowing down all drawing operations (performance bug only).
|
|
(gxacpath.c)
|
|
- stroking in a rotated coordinate system sometimes thought lines
|
|
were always thin when they actually weren't. (gxstroke.c)
|
|
- An unsigned quantity wasn't properly converted to signed, possibly
|
|
causing band path coordinates to get mangled. (gxclread.c)
|
|
- A bug in the Borland compiler caused an unsigned quantity to be
|
|
interpreted as signed, causing band path coordinates to get mangled.
|
|
(gxclread.c)
|
|
|
|
Changes structure type pointers on 16-bit segmented systems to full
|
|
32-bit pointers. This will increase time and space requirements very
|
|
slightly on these systems. (gsmemory.h, gxobj.h)
|
|
|
|
Changes the memory manager so that object finalization code may safely free
|
|
objects. (gsmemory.h, gsstruct.h, gsalloc.c, gsmemory.c)
|
|
|
|
Refactors the Type 1 CharString interpreter so it can be included in
|
|
the imager library. (gstype1.h, gxtype1.h, gstype1.c)
|
|
|
|
Starts to refactor the implementation of band lists in memory so that it can
|
|
use any encoding/decoding filter. Currently this choice is made at compile
|
|
time, but it could easily be made dynamic. (gxclmem.h, gxclmem.c)
|
|
|
|
Starts to refactor image rendering so that, like path filling and stroking,
|
|
it only uses imager state and can be done after banding. (gxcmap.h,
|
|
gxdraw.h, gximage.h, gsimage*.c, gxcmap.c)
|
|
|
|
Speeds up copy_mono for 2-bit-per-pixel devices a little. (gdevm2.c)
|
|
|
|
Implements an optimized copy_alpha for 24-bit memory devices. (gdevmem.h,
|
|
gdevm24.c)
|
|
|
|
Speeds up filling rectangles significantly. (gsbitops.c)
|
|
|
|
Changes the band list rasterizer to use the memory space of the device
|
|
rather than the C heap: our allocator is considerably faster than malloc.
|
|
(gxclread.c)
|
|
|
|
Speeds up stroking a little, especially in 90 degree rotated coordinate

systems. (gxstroke.c)

<h2><a name="Version3.64"></a>Version 3.64 (limited, incremental) (1/27/96)</h2>
|
|
|
|
<p>
|
|
This release fixes a few more bugs, including some serious bugs in band
|
|
lists, and adds pdfmark processing to the PDF writer. The PDF writer is
|
|
still not fit for real use, since it converts all text characters into 720
|
|
dpi bitmaps and turns images into zillions of tiny rectangles (!), but it
|
|
should be producing legal output.

graphics operators. (lib.doc)
|
|
|

|
|
- The install rule tried to install gs.1.1 etc. rather than gs.1

documentation. (gs_init.ps)
|
|
|
|
Adds -A-, -E-, and -Z-... to turn off debugging flags. (gs.c)

|
- Fonts produced by rollconv.ps left a couple of items on the

operand stack, and left array packing set to true. (rollconv.ps)
|
|
|
|
Makes ansi2knr require that the first token after a function header be a
|
|
left brace on the next line, so it can cope with some macros in IJG release
|
|
6a. Also updates it to work better without the GNU configure machinery, and
|

|
|
- The PDF writer produced invalid output for 0-width, 0-height
|
|
images. (gdevpdfi.c)
|
|
- The PDF writer wasn't a page device. (gdevpdf.c)
|
|
- The PDF writer assigned the Contents node rather than the Pages

node as the Parent of each page. (gdevpdfx.h, gdevpdf.c)
|
|
|
|
Corrects the margin information for the DeskJet printers to be the actual
|
|
values observed on a printer; all of the values in the file were wrong.
|
|
(gdevdjet.c)
|
|
|
|
Adds pdfmark recognition and conversion to the PDF writer. All documented
|
|
pdfmarks (ANN, ARTICLE, DEST, DOCINFO, DOCVIEW, LNK, OUT, PAGE, PAGES, PS)
|
|
are recognized and converted, but some of them are not converted correctly.
|
|
(gs_pdfwr.ps, gdevpdfx.h, gdevpdf.c, gdevpdfm.c)
|
|
|
|
Adds recognition of all Distiller parameters, except *ImageDict, to the PDF

|
writer. Currently only ASCII85EncodePages actually has any effect.
|
|
(gs_pdfwr.ps, gdevpdfx.h, gdevpdfp.c)
|
|
|
|
Ensures that PDF output files include at least a default Info dictionary.
|
|
(gdevpdf.c)
|
|
|
|
Changes the handling of coordinates in PDF output files so that the scale is
|
|
always 72 dpi, and so that each graphics operator is on a line by itself,
|
|
for compatibility with Adobe Illustrator. (gdevpdfx.h, gdevpdf*.c)
|
|
|
|
Adds a driver for ImageMagick's MIFF format. The driver currently only

</pre><h3><a name="V3.64_Platforms"></a>Platforms</h3><pre>
|
|
|

Changes the gp_check_interrupts platform procedure so that instead of just
|
|
returning a Boolean, it can now also return a negative error code. THIS IS
|
|
(THEORETICALLY) A NON-BACKWARD-COMPATIBLE CHANGE. However, since all
|
|
implementations of this procedure should only have been returning 0 or 1 up

to now, no existing code should need to be changed. (gpcheck.h, gsmisc.c)

- Alpha computations for graphics could be seriously incorrect (bug
|
|
introduced in 3.6x). (gdevabuf.c)
|
|
- The length of the next_data_x command for the fill_mask operation

|
|
- An extern was omitted, causing linker warnings. (gxdevice.h)

|
outside the current band, the rest of the path was drawn in the wrong place
|
|
(bug introduced in 3.6x). (gxclpath.c)
|
|
|
|
Speeds up image interpolation on machines with slow floating point.
|
|
(siscale.h, siscale.c)
|
|
|
|
Speeds up interpolated images when using device color spaces. (gxcvalue.h,
|
|
gxfrac.h, gdevht.c, gxcmap.c, gsimage.c, gsimage3.c)
|
|
|
|
Speeds up color mapping a little by removing tests and calls in favor of
|
|
code copying. (gxcmap.c)
|
|
|
|
Implements RasterOp for 24-bit RGB devices. (gdevm8.c, gdevm24.c,
|
|
gdevmrop.c)

<h2><a name="Version3.63"></a>Version 3.63 (limited, incremental) (1/14/96)</h2>
|
|
|
|
<p>
|
|
This release has the usual collection of bug fixes, and two significant
|
|
additions: AccurateScreens, and the first draft of a PostScript->PDF
|
|
converter ("distiller").
|
|
|
|
<h3><a name="V3.63_Documentation"></a>Documentation</h3><pre>
|
|
Fixes bugs:
|
|
- Some documentation for pstoppm.ps was out of date. (psfiles.doc)
|
|
- Documentation for acctest.ps, view*.ps, and zeroline.ps was
|
|
missing. (psfiles.doc)
|
|
- The documentation for rollconv.ps omitted the .CSR file.
|
|
(rollconv.ps)
|
|
|
|
Removes an inappropriate RCS Id line. (gs.1)
|
|
|
|
Adds a list of paper sizes to the man page. (gs.1)
|
|
|
|
Suggests that driver authors use parameterization rather than copying when
|
|
possible. (drivers.doc)
|
|
|
|
Adds an announcement of Ghostscript support on CompuServe. (README)
|
|
|
|
Documents the new -dCOLORSCREEN switch and the existing -dDITHERPPI=lpi
|
|
switch. (use.doc)
|
|
|
|
Notes that the OS/2 implementation now requires EMX/GCC 0.9b rather than
|
|
0.9a. (install.doc)
|
|
|
|
Adds some new man pages. (pdf2ps.1, ps2ascii.1)
|
|
|
|
Greatly expands lib.doc. (lib.doc)
|
|
|
|
</pre><h3><a name="V3.63_Procedures"></a>Procedures</h3><pre>
|
|
|
|
Fixes bugs:
|
|
- The pg target for Unix platforms didn't include some necessary
|
|
additional X11 libraries. (unix-end.mak)
|
|
- The Unix library makefile didn't define CCAUX or CCLEAF.
|
|
(ugcclib.mak)
|
|
- Unix systems didn't `install' some .ps files. (unix-end.mak)
|
|
|
|
Extends genconf so that features at the library level can have
|
|
initialization procedures. (gconf.c, genconf.c, gsinit.c)
|
|
|
|
Adds a -dCOLORSCREEN[=false] switch to force enabling or disabling of
|
|
4-color screens. (gs_init.ps, gs_setpd.ps)
|
|
|
|
</pre><h3><a name="V3.63_Utilities"></a>Utilities</h3><pre>
|
|
|
|
Fixes bugs:
|
|
- The prfont utility didn't leave enough of a margin on the left.
|
|
(prfont.ps)
|
|
- The ps2ascii utility still created files _temp_.out and _temp_.err
|
|
even though they are no longer used. (ps2ascii.ps)
|
|
- The acctest.ps file was empty, rather than including a test
|
|
program. (acctest.ps)
|
|
|
|
Adds ps2pdf[.bat] scripts for invoking the new pdfwrite driver. (ps2pdf,
|
|
ps2pdf.bat, unix-end.mak)
|
|
|
|
</pre><h3><a name="V3.63_Drivers"></a>Drivers</h3><pre>
|
|
|
|
Fixes bugs:
|
|
- The x11alpha driver had a patch that suppressed output in many
|
|
cases. (gdevxalt.c)
|
|
- The X driver set up a parameter incorrectly in copy_color.
|
|
(gdevx.c)
|
|
- An explicit cast was needed to handle a 'const' problem.
|
|
(gdevpng.c)
|
|
|
|
Adds a pdfwrite driver that creates syntactically correct PDF output. The
|
|
output is only reasonable for fill/stroke graphics, not for text or images.
|
|
(iscan.h, sa85x.h, sfilter.h, gdevpdf.c, sfilter2.c, zfdecode.c)
|
|
|
|
</pre><h3><a name="V3.63_Platforms"></a>Platforms</h3><pre>
|
|
|
|
Fixes bugs:
|
|
- The test for WinExec failure on Win32 was incorrect. (gp_mswin.c)
|
|
- getenv was declared redundantly on OS/2. (gp_os2.c)
|
|
- gs16spl.c was missing <string.h>. (gs16spl.c)
|
|
|
|
</pre><h3><a name="V3.63_Interpreter"></a>Interpreter</h3><pre>
|
|
|
|
Fixes bugs:
|
|
- Images read data in smaller and smaller increments (performance
|
|
bug only). (zpaint.c)
|
|
- Images with MultipleDataSources=true and two or more DataSources
|
|
referencing the same stream could get confused. (zpaint.c)
|
|
- Invoking setpagedevice with an undefined key, even with Policy =
|
|
1, caused an error. (gs_setpd.ps)
|
|
- IEEE floats in binary tokens or encoded number strings were read
|
|
incorrectly on CPUs that use non-IEEE floating point. (ibnum.c)
|
|
|
|
Adds a 'const' to the second parameter of zimage_setup. (zimage2.c,
|
|
zpaint.c)
|
|
|
|
Encapsulates the filling of free memory blocks in a macro. (igc.c,
|
|
igcstr.c)
|
|
|
|
</pre><h3><a name="V3.63_Interpreter_PDF"></a>Interpreter (PDF)</h3><pre>
|
|
|
|
Fixes bugs:
|
|
- If the first line of a file began with % but the line was longer
|
|
than 255 characters, an error occurred. (pdf_main.ps)
|
|
- Masked images didn't set the color before drawing. (gs_pdf.ps)
|
|
- Extraneous blank lines in the trailer or cross-reference region
|
|
caused an error. (pdf_base.ps, pdf_main.ps)
|
|
|
|
</pre><h3><a name="V3.63_Streams"></a>Streams</h3><pre>
|
|
|
|
Speeds up image interpolation a little. Much more could be still be done.
|
|
(siscale.c)
|
|
|
|
</pre><h3><a name="V3.63_Library"></a>Library</h3><pre>
|
|
|
|
Fixes bugs:
|
|
- An error in handling a boundary condition could cause a horizontal
|
|
streak of pixels to be turned on or off when it shouldn't be. (gxfill.c)
|
|
- The new scan-line-based filling loop could write pixels twice.
|
|
(The old trapezoid-based loop still does write pixels twice.) (gxfill.c)
|
|
- For multi-plane images, gs_image_next only sets *pused for the
|
|
last plane; this wasn't documented. (gsimage.h)
|
|
- Images with MultipleDataSources=true and two or more DataSources
|
|
referencing the same stream could get confused. (gsimage.h, gsimage0.c)
|
|
- 12-bit gray images caused an invalid memory access. (gsimage.c)
|
|
- Nearly-zero-thickness lines didn't get filled, because the hack
|
|
that compensates for this peculiarity of the MS Windows PostScript driver
|
|
accidentally got disabled. (gxfill.c)
|
|
- Some casts to remove 'const' were omitted. (gxclread.c)
|
|
- 1-line-high bitmaps could get written in the band list with an
|
|
inconsistent number of bytes, causing errors when reading. (gxcldev.h,
|
|
gxclbits.c, gxclist.c, gxclpath.c, gxclread.c)
|
|
- Isolated dots produced by round caps usually disappeared. (They
|
|
still disappear sometimes.) (gxstroke.c)
|
|
- On 16-bit platforms, the computation of t2 and t3 in
|
|
gx_curve_x_at_y could overflow, leading to incorrect output. (gxpcopy.c)
|
|
- Stroking horizontal or vertical lines could produce variations of
|
|
1 pixel in the line width. (gxstroke.c)
|
|
- The default clipping region for band rendering was too large,
|
|
leading to wasted work. (gxclread.c)
|
|
- Guarantees no double pixel writing when necessary, i.e., when a
|
|
non-idempotent RasterOp is selected. (gsropt.h, gxfill.c)
|
|
- For unrotated black-and-white images, one column of pixels at the
|
|
right edge of the image might be incorrect. (gsimage1.c)
|
|
- A const pointer was passed inappropriately. (gxistate.h,
|
|
gscoord.c)
|
|
- CIE color conversion could address 1 element beyond the end of an
|
|
array, with unpredictable results. (gscie.c)
|
|
|
|
Separates out the higher-level band list facilities, so they can be an
|
|
optional feature. (lib.mak, gxcldev.h, gxclpath.h, gxclbits.c, gxclist.c,
|
|
gxclpath.c, gxclread.c)
|
|
|
|
Implements bitmap (fill_mask) clipping in the band list. (gxcldev.h,
|
|
gxclpath.h, gxclist.c, gxclpath.c, gxclread.c)
|
|
|
|
Starts to separate out the RasterOp facility as an optional feature.
|
|
(lib.mak, gxdevice.h, gxdevrop.h, gdevdflt.c, gdevmrop.c)
|
|
|
|
Encapsulates the filling of free memory blocks in a macro, at the request of
|
|
a licensee. (gdebug.h, gsmdebug.h, gsmemory.h, gs.c, gsalloc.c, gsmemory.c,
|
|
gxbcache.c)
|
|
|
|
Speeds up fill_rectangle for 32-bit devices. (gdevm32.c)
|
|
|
|
Speeds up path writing in band lists a little. (gxclpath.c)
|
|
|
|
Implements AccurateScreens along the lines described in the Adobe
|
|
documentation. The current implementation can produce very large
|
|
super-cells, so it will not always be able to actually increase the screen
|
|
accuracy. (gxdht.h, gsht.c, gshtscr.c)

<h2><a name="Version3.62"></a>Version 3.62 (limited, incremental) (12/26/95)</h2>
|
|
|
|
<p>
|
|
This release makes some licensee-requested improvements in the garbage
|
|
collector and fixes a couple of minor bugs. It also constitutes a
|
|
checkpoint for the forthcoming forked 3.53 release.
|
|
|
|
<h3><a name="V3.62_Documentation"></a>Documentation</h3><pre>
|
|
Notes that for Win32s, gs16spl.exe must be in the same directory as
|
|
gswin32.exe. (install.doc)
|
|
|
|
Changes `3.N' to a real version number in the man page. (gs.1)
|
|
|
|
Adds a reference to dos-psv, another "dumb terminal" user interface for
|
|
Ghostscript intended for MS-DOS users. (README)
|
|
|
|
</pre><h3><a name="V3.62_Procedures"></a>Procedures</h3><pre>
|
|
|
|
Fixes bugs:
|
|
- The stack size for some of the PC platforms was set too small.
|
|
(watc.mak, watcwin.mak)
|
|
|
|
Changes the default value of ORIENT1 from false to true, i.e., assumes that
|
|
a value of 1 for the orientation parameter of setpageparams indicates
|
|
portrait orientation. THIS IS A NON-BACKWARD-COMPATIBLE CHANGE. It only
|
|
affects files created for roll-media imagesetters. (gs_init.ps, use.doc)
|
|
|
|
</pre><h3><a name="V3.62_Interpreter"></a>Interpreter</h3><pre>
|
|
|
|
Fixes bugs:
|
|
- The definition of the op_index_op_array_table macro had an
|
|
incorrect trailing semicolon. (opdef.h)
|
|
- Setting the PageSize policy to 1 and then trying to set the page
|
|
size caused an error if FIXEDMEDIA was selected. (gs_setpd.ps)
|
|
|
|
Changes the garbage collector marking phase so that instead of just using a
|
|
single block (allocated, free, or default) for the mark stack, it can chain
|
|
all three types of block together. (igc.h, igc.c, igcstr.c, ilocate.c)
|
|
|
|
Refactors the garbage collector slightly to reduce inter-module
|
|
dependencies. (int.mak, igc.h, igcstr.h, igcstr.c)
|
|
|
|
Changes the garbage collector to keep track of ranges within each chunk that
|
|
must be scanned if the mark stack overflows. (gxalloc.h, igc.c)
|
|
|
|
Adds [write]===[only] procedures, which act like == but also print the
|
|
contents of dictionaries, and ppstack, which acts like pstack but uses ===.
|
|
Changes ESTACKPRINT and OSTACKPRINT to use === rather than ==. (gs_init.ps,
|
|
gs_setpd.ps)
|
|
|
|
</pre><h3><a name="V3.62_Interpreter_PDF"></a>Interpreter (PDF)</h3><pre>
|
|
|
|
Fixes bugs:
|
|
- If a PDF file substituted a calibrated color space for the
|
|
DeviceGray or DeviceRGB color space using a ColorSpace resource, the
|
|
PostScript file that pdf2ps produced from that PDF file caused an error.
|
|
(gs_pdf.ps)
|
|
|
|
</pre><h3><a name="V3.62_Library"></a>Library</h3><pre>
|
|
|
|
Fixes bugs:
|
|
- The debugging code for checking the sorting of line lists didn't
|
|
check for an empty list. (gxfill.c)
|
|
|
|
</pre>
|
|
|
|
<h2><a name="Version3.61"></a>Version 3.61 (limited) (12/10/95)</h2>
|
|
|
|
<p>
|
|
This limited release fixes a few bugs (including a couple that significantly
|
|
affected character quality) and also includes some substantial performance
|
|
improvements.
|
|
|
|
<h3><a name="V3.61_Documentation"></a>Documentation</h3><pre>
|
|
Fixes bugs:
|
|
- The directory name for the PNG library was incorrect.
|
|
(libpng.mak)
|
|
- The analysis of curve monotonocity in gxpcopy.c had an error.
|
|
(gxpcopy.c)
|
|
|
|
Changes the subdirectory names for zlib and libpng to be consistent.
|
|
(make.doc)
|
|
|
|
Documents a possible problem with object file format incompatibilities in
|
|
certain versions of Linux. (make.doc)
|
|
|
|
Documents the new distinction between devices and device prototypes.
|
|
(language.doc)
|
|
|
|
Adds a pointer to DEC's free pstotext utility. (README)
|
|
|
|
</pre><h3><a name="V3.61_Procedures"></a>Procedures</h3><pre>
|
|
|
|
Fixes bugs:
|
|
- zlib.mak omitted some files in the encoding module dependencies.
|
|
(zlib.mak)
|
|
- os2.mak referred to png.mak rather than libpng.mak. (os2.mak)
|
|
- The png devices didn't include gdevpccm.$(OBJ) as a required file.
|
|
(devs.mak)
|
|
- Some modules in lib.mak referred to stream.h, which was defined in
|
|
int.mak. (int.mak, lib.mak)
|
|
- Quite a few dependencies on header files were missing from the
|
|
makefiles. (int.mak, lib.mak, *.mak)
|
|
|
|
Adds a 'pg' target to the Unix makefiles, for building profiling
|
|
configurations. (unix-end.mak)
|
|
|
|
</pre><h3><a name="V3.61_Utilities"></a>Utilities</h3><pre>
|
|
|
|
Fixes bugs:
|
|
- Type 1 fonts in which some characters are defined by PostScript
|
|
procedures couldn't be compiled. (ccfont.h, iccfont.c, font2c.ps)
|
|
- pdf2ps didn't write Widths or Encoding in the converted file,
|
|
producing incorrect spacing and incorrect characters. (pdf_2ps.ps)
|
|
- markhint.ps didn't handle the Type 1 'div' operator, causing
|
|
typecheck errors. (markhint.ps)
|
|
- markhint.ps ignored the hstem3 and vstem3 hints. (markhint.ps)
|
|
|
|
Changes the rollconv.ps utility to produce files whose names conform to the
|
|
8.3 length restriction, and to reduce the fixed RAM overhead for Kanji
|
|
fonts. (rollconv.ps)
|
|
|
|
Adds a utility for detecting compiler problems that affect Ghostscript.
|
|
(bughunt.sh)
|
|
|
|
</pre><h3><a name="V3.61_Drivers"></a>Drivers</h3><pre>
|
|
|
|
Adds anti-aliasing capability (-dTextAlphaBits and -dGraphicsAlphaBits) to
|
|
the PGM and PPM drivers. (gdevpbm.c)
|
|
|
|
Declares the static_procs member of the device structure as const *. This
|
|
should have been done a long time ago! (drivers.doc, gxdevice.h)
|
|
|
|
</pre><h3><a name="V3.61_Platforms"></a>Platforms</h3><pre>
|
|
|
|
Fixes bugs:
|
|
- Printing didn't work in 32-bit MS Windows environments.
|
|
(bcwin32.mak, gdevmswn.c, gp_mswin.c)
|
|
- There were some compatibility problems with IBM C. (os2.mak,
|
|
gsdll.h, gdevpm.c, gp_os2.c)
|
|
|
|
Adds the PNG drivers to the 32-bit MS Windows and OS/2 makefiles.
|
|
(bcwin32.mak, os2.mak)
|
|
|
|
Adds a conditional to work around a bug in gcc 2.7.x (it didn't recognize
|
|
that the target of a const T * might still be mutable through aliasing).
|
|
(stdpre.h)
|
|
|
|
</pre><h3><a name="V3.61_Fonts"></a>Fonts</h3><pre>
|
|
|
|
Fixes bugs:
|
|
- Rasterizing a character in a Type 1 font with an invalid FontBBox
|
|
left some garbage on the operand stack (bug introduced in 3.52 or 3.60).
|
|
(gs_type1.ps)
|
|
- The font substitution algorithm could fail or loop. (gs_fonts.ps)
|
|
|
|
Adds a little more support for CID fonts and CMaps. (gs_cidfn.ps,
|
|
gs_cmap.ps)
|
|
|
|
</pre><h3><a name="V3.61_Interpreter"></a>Interpreter</h3><pre>
|
|
|
|
Fixes bugs:
|
|
- An #include <memory_.h> was missing. (ziodev.h)
|
|
- Scanner-detected errors (primarily syntaxerror) didn't report the
|
|
file position. (gs_init.ps)
|
|
- Rotated characters were rendered incorrectly (bug introduced in
|
|
3.52). (gstype1.c)
|
|
- Some compilers got upset about the use of 'dict' as a variable
|
|
name. (zdict.c)
|
|
- Operand stack overflows sometimes didn't set the "requested" field
|
|
correctly. (interp.c)
|
|
- Using -dBufferSpace= with a non-printer device caused an error.
|
|
(gs_init.ps)
|
|
|
|
Adds zlibEncode/Decode filters. (int.mak, zfzlib.c)
|
|
|
|
Separates devices from device prototypes. Prototypes, which lack the
|
|
writable attribute, cannot be installed as the current device or have their
|
|
parameters changed. This change allows Ghostscript to be exited and
|
|
restarted without being reloaded, which solves some problems with DLL
|
|
usage. ****** WE HAD TO SUBVERT THIS CHANGE BECAUSE OF MEMORY MANAGER
|
|
PROBLEMS, by making zgetdevice return a writable reference to the
|
|
prototype. (We finally fixed this in release 3.65.) (gs_init.ps, iref.h,
|
|
opcheck.h, zdevice.c, ztype.c, zwppm.c)
|
|
|
|
Extends the client API to allow for pushing values onto the operand stack.
|
|
(imain.h, gs.c, gsmain.c)
|
|
|
|
Defines a .setdefaultscreen procedure that sets the default halftone screen,
|
|
transfer function, and stroke adjustment for the current device. Changes
|
|
selectdevice and setpagedevice so that they call .setdefaultscreen;
|
|
setpagedevice calls .setdefaultscreen before calling the Install procedure,
|
|
so that Install can set different parameters if it wishes. Note that
|
|
setdevice does not do this. (gs_init.ps, gs_setpd.ps)
|
|
|
|
</pre><h3><a name="V3.61_Interpreter_PDF"></a>Interpreter (PDF)</h3><pre>
|
|
|
|
Fixes bugs:
|
|
- Tf set the current text font twice, and interacted with pdf2ps in
|
|
an awkward way. (gs_pdf.ps, pdf_2ps.ps, pdf_font.ps)
|
|
- If a font had variant Widths, it could get confused in the cache
|
|
with the underlying font. (pdf_font.ps)
|
|
- If a character appeared twice in an encoding and the font
|
|
specified different Widths values for the two occurrences, the last Width
|
|
would be used. We patched this to ignore zero Widths, which is not the
|
|
correct solution but which almost always produces correct output.
|
|
(pdf_font.ps)
|
|
- Arrays containing nulls didn't print out correctly (bug introduced
|
|
in 3.60). (gs_init.ps)
|
|
- Some PDF files contain very large dictionaries, which caused a
|
|
stackoverflow. (pdf_base.ps)
|
|
|
|
Speeds up the initial processing of PDF files by caching the map from page
|
|
numbers to page objects, and by not scanning the outlines if we aren't
|
|
producing PostScript output. (pdf_2ps.ps, pdf_base.ps, pdf_main.ps)
|
|
|
|
</pre><h3><a name="V3.61_Streams"></a>Streams</h3><pre>
|
|
|
|
Adds zlibEncode/Decode filters. (lib.mak, szlibx.h, szlibc.c, szlibd.c,
|
|
szlibe.c)
|
|
|
|
</pre><h3><a name="V3.61_Library"></a>Library</h3><pre>
|
|
|
|
Fixes bugs:
|
|
- glyphshow displayed a character with code 0 rather than the
|
|
requested character (bug introduced in 3.60.) (gschar.c)
|
|
- If trimming white space around a character reduced its raster, the
|
|
character was garbled in the cache (bug introduced in 3.60.) (gxccman.c)
|
|
- colorimage would incorrectly convert white pixels to black if the
|
|
image color space was CMYK, the current color space was not CMYK, and the
|
|
number of bits per pixel was 4 or 8. (gsimage2.c)
|
|
- One of the clipping tests for images was backwards (bug introduced
|
|
in 3.60). (gsimage.c)
|
|
- Type 1 fonts that used the Flex feature applied hints to the path
|
|
multiple times, causing dropouts, uneven stems, and other problems (bug
|
|
probably introduced in 3.21). (gstype1.c)
|
|
- If a Type 1 font used the Flex feature within the accent of an
|
|
accented character defined with seac, the shape of the accent could be
|
|
distorted. (gxtype1.h, gstype1.c)
|
|
- If a Type 1 font changed hints using the hint replacement facility
|
|
when the last operation was a closepath, the old hints would be applied a
|
|
second time, distorting the shape. (gxhint3.c)
|
|
- Band lists could read garbage beyond the end of data for a band,
|
|
causing unpredictable errors (bug introduced in 3.60). (gxclread.c)
|
|
- If the bounding box of the path for fill_path or stroke_path went
|
|
outside the device page boundary when banding, out-of-bounds memory
|
|
references occurred (bug introduced in 3.60). (gxdevice.h, gxclpath.c)
|
|
|
|
Adds an alternative implementation of the core path filling algorithm that
|
|
is much faster on objects with curves but doesn't handle Y fattening. This
|
|
is the implementation that will normally be used for rasterizing characters.
|
|
This implementation rasterizes curves directly, without flattening them.
|
|
(gxfixed.h, gxpath.h, gzpath.h, gsdps1.c, gxfill.c, gxpcopy.c, gxpdash.c)
|
|
|
|
Speeds up the flattening of curves substantially by omitting more redundant
|
|
points. (gxpcopy.c)
|
|
|
|
Speeds up character bitmap compression a little more. (gsbitops.h,
|
|
gdevabuf.c, gsbitops.c, gxccman.c)
|
|
|
|
Speeds up anti-aliased graphics a bit by computing a bounding box before
|
|
converting from oversampling to alpha values, and by speeding up the
|
|
bounding box computation itself. (gsbitops.h, gdevabuf.c, gsbitops.c,
|
|
gxccman.c)

<h2><a name="Version3.60"></a>Version 3.60 (limited) (11/20/95)</h2>
|
|
|
|
<p>
|
|
(Note: release numbers 3.54 through 3.59 were deliberately skipped.) This
|
|
internal release includes a major redesign of band lists in order to reduce
|
|
their size for embedded implementations, to move towards supporting "vector"
|
|
output formats, and to further separate the imager library from the language
|
|
interpreters.
|
|
|
|
<h3><a name="V3.60_Documentation"></a>Documentation</h3><pre>
|
|
Fixes bugs:
|
|
- A comment was incorrect. (viewpbm.ps)
|
|
- The PixelDifference filters were not documented. (language.doc)
|
|
- The change from currenttime to .currenttime wasn't documented.
|
|
(language.doc)
|
|
- gs.1 incorrectly stated that the default font directory name
|
|
included the version number. (gs.1)
|
|
- The -g and -r switches didn't specify that the units for their
|
|
arguments are pixels and pixels per inch respectively. (use.doc)
|
|
- The PageOffset page device parameter wasn't listed.
|
|
(language.doc)
|
|
|
|
Changes copy_mono and copy_color to optional procedures. (drivers.doc)
|
|
|
|
Adds a reference to ps_view.ps, a "dumb terminal" user interface for
|
|
Ghostscript intended for MS-DOS users. (README)
|
|
|
|
Splits off the documentation on installing Ghostscript into a separate file.
|
|
(readme, install.doc, use.doc)
|
|
|
|
Adds documentation on the data format produced by the standard LZWEncode
|
|
filter. (readme, lzwce.doc)
|
|
|
|
Clarifies XLIBDIR vs. XLIBDIRS. (make.doc)
|
|

|
|
|
|
Fixes bugs:
|
|
- The rule for building dfaxhigh.dev had a typo. (devs.mak)
|
|
- The dependencies for gdevpipe.h were missing errno__h and
|
|
string__h. (unixtail.mak)
|
|
- The geninit program (the implementation of COMPILE_INITS=1) didn't
|
|
parse the command line properly, and didn't check for PostScript files
|
|
properly. (geninit.c)
|
|
- ccfontab.c was omitted from the fileset. The easiest way to fix
|
|
this was to rename it to icfontab.c. (gs.mak, int.mak, ccfontab.c)
|
|
- The Unix makefiles installed caption.ls (a typo) rather than
|
|
caption.ps. (unix-end.mak)
|
|
- XLIBDIR, for dynamic library access, wasn't defined. (*head.mak,
|
|
*tail.mak, ugcclib.mak)
|
|
|
|
Adds the PNG and ZLIB makefiles to the fileset. (*.mak, png.mak, zlib.mak,
|
|
tar_cat)
|
|
|
|
Puts the PixelDifference filters in the standard Level 2 set, since the LZW
|
|
filters may invoke them (a post-Red Book addition to the PostScript language
|
|
definition). (int.mak)
|
|
|
|
Adds -Wcast-qual to the gcc compiler flags. (gcc-head.mak)
|
|
|
|
Adds the PNG drivers to the standard Unix configurations.
|
|
(ansi/cc-/gcc-head.mak)
|
|
|
|
Adds a -dNOFONTPATH switch to suppress any consultation of the FONTPATH
|
|
variable or the GS_FONTPATH environment variable. (gs_fonts.ps, gs_init.ps)
|
|
|
|
</pre><h3><a name="V3.60_Utilities"></a>Utilities</h3><pre>
|
|
|
|
Fixes bugs:
|
|
- The default scaling for viewing PBM files was computed
|
|
incorrectly. (viewpbm.ps)
|
|
- ps2ascii left a value on the stack for each unrecognized character
|
|
it processed, eventually causing a stackoverflow. (ps2ascii.ps)
|
|
|
|
Changes viewpbm.ps so that it simply defines P1 through P6, allowing PBM
|
|
files to be executed with 'run'. (viewpbm.ps)
|
|
|
|
Adds a small benchmark to crudely measure hardware/system performance. The
|
|
same file can either be compiled as a C program or executed as a PostScript
|
|
program. (bench.c)
|
|
|
|
Adds a few PPD files to the distribution. There will probably be more as
|
|
time goes on. (tar_gs, unix-end.mak)
|
|
|
|
Updates the Unix lpr scripts to handle a wider variety of device options.
|
|
(unix-lpr.doc, lprsetup.sh, unix-lpr.sh)
|
|
|
|
Adds a utility for converting files produced by Macromedia's Rollup program
|
|
to a Type 0 form directly usable by Ghostscript. (rollconv.ps)
|
|
|
|
</pre><h3><a name="V3.60_Drivers"></a>Drivers</h3><pre>
|
|
|
|
Fixes bugs:
|
|
- Forwarding devices passed an incorrect first argument when
|
|
forwarding a copy_rop operation. (gsdevice.c)
|
|
- Because of a typo, the LaserJet drivers had incorrect margins.
|
|
This was probably a new bug in 3.5x. (gdevdjet.c)
|
|
- A private name was duplicated. (gdevtfax.c)
|
|
- The x11alpha driver passed invalid colors to the X library.
|
|
(gdevxalt.c)
|
|
- The x11alpha driver set the blue component of colors incorrectly.
|
|
(gdevxalt.c)
|
|
- Some `const' declarations were missing. (gdevtifs.c, gdevtfnx.c,
|
|
gdevxxf.c)
|
|
- The size of A4 paper was slightly inconsistent across drivers.
|
|
(gdevdjet.c, gdevl256.c)
|
|
|
|
Provides default implementations of copy_mono and copy_color in terms of
|
|
fill_rectangle. (gxdevice.h, gsdevice.c)
|
|
|
|
Adds forwarders for sync_output and output_page. (gxdevice.h, gsdevice.c)
|
|
|
|
Adds new optional procedures to the driver interface:
|
|
- fill_path for filling a path with a color;
|
|
- stroke_path for stroking a path;
|
|
- fill_mask for painting a color through a mask.
|
|
The default implementations use the existing rasterizer algorithms. This
|
|
involves a NON-BACKWARD-COMPATIBLE change to the parameters of a few
|
|
internal routines:
|
|
gs_currentlineparams
|
|
gx_fill_path, gx_fill_path_only, gx_path_expand_dashes, gx_path_flatten
|
|
and two externally visible routines not part of standard PostScript:
|
|
gs_setfilladjust, gs_currentfilladjust
|
|
(gdevmem.h, gdevprn.h, gspath.h, gspenum.h, gxcpath.h, gxdevice.h, gxdraw.h,

gxpcmap.c, gxpcopy.c, gxstroke.c)
|
|
|
|
Makes major changes to the dithering algorithm for the color DeskJet and
|
|
BubbleJet drivers, contributed by a user. (gdevcdj.c)
|
|
|
|
Adds a contributed 12-bit RGB TIFF driver. (gdevtfnx.c)
|
|
|
|
</pre><h3><a name="V3.60_Platforms"></a>Platforms</h3><pre>
|
|
|
|
Fixes bugs:
|
|
- The printjob created by Ghostscript was called "Ghostscirpt"
|
|
instead of "Ghostscript". (gp_os2.c)
|
|
- An "export" declaration was omitted from DllInit. (gp_mswin.c)
|
|
|
|
Removes gp_get_clock (its interface was changed from calendar
|
|
days/milliseconds to epoch seconds/nanoseconds in an undocumented,
|
|
NON-BACKWARD-COMPATIBLE change in 3.51), and adds a new gp_get_realtime
|
|
procedure that returns epoch seconds/nanoseconds. This too is a
|
|
NON-BACKWARD-COMPATIBLE change; it is required because we overlooked the
|
|
prior change in a batch of user-contributed code. (gp.h, gp_*.c)
|
|
|

</pre><h3><a name="V3.60_Interpreter"></a>Interpreter</h3><pre>
|
|
|
|
Fixes bugs:
|
|
- The setup for the CCITTFax filters set the 'raster' element
|
|
redundantly. (zfdecode.c)
|
|
- currentscreen and currentcolorscreen could give an error if the
|
|
current screen was set with sethalftone (or, for currentscreen,
|
|
setcolorscreen). (gs_dps1.ps)
|
|
- The font operators didn't work properly if a PostScript file
|
|
redefined certain operator names. (gs_res.ps)
|
|
- The CCITTFax filters imposed a limit of 9999 Rows or Columns. The
|
|
new limit is 32000. (zfdecode.c)
|
|
- Streams could get removed from a bookkeeping list prematurely, and
|
|
wind up dangling. (zfile.c)
|
|
- The garbage collector didn't ask for large enough a mark stack,
|
|
and only used half of what it got. (This was only a performance problem.)
|
|
(igc.c)
|
|
- Two private names duplicated names in a vendor library. (zbseq.c)
|
|
- Type 1 fonts didn't enforce the maximum value of BlueScale, which
|
|
caused some faulty fonts produced by Fontographer to produce incorrect
|
|
output. (zfont1.c)
|
|
- cvs / cvrs / = didn't produce Adobe-compatible output.
|
|
(gs_init.ps, iutil.h, iutil.c, zfileio.c)
|
|
- Multiple -I switches set the search path incorrectly. (gsmain.c)
|
|
- Many `const' declarations were missing. (icie.h, idparam.h,
|
|
iref.h, iutil.h, idparam.c, iinit.c, ilocate.c, iname.c, interp.c, iparam.c,
|
|
iutil.c, zcie.c, zfile.c, zgstate.c, ziodev.c, ztype.c)
|
|
- Fonts could wind up with a pointer to the wrong VM space, causing
|
|
potential GC or save/restore confusion. (zfont2.c)
|
|
- upath could leave garbage on the stack if it failed. (gs_dps1.ps)
|
|
|
|
Speeds up rasterizing characters into the cache a little. (gs_type0.ps)
|
|
|
|
Changes the default limit on the size of cached characters from the maximum
|
|
of (18 points or 5 times the "average" character size) to (18 points or 1%
|
|
of the total cache size). (gs_init.ps)
|
|
|
|
Adds the DecodedByteAlign parameter to the CCITTFax filters. (zfdecode.c)
|
|
|
|
Updates some code for compatibility with the new fill_path driver procedure.
|
|
(zupath.c)
|
|
|
|
Replaces .set/currentfilladjust with .set/currentfilladjust2, and defines
|
|
the former in terms of the latter. (gs_init.ps, zgstate.c)
|
|
|
|
Extends the make[word]imagedevice operators to accept palette values of 16,
|
|
24, and 32, for creating true-color image devices. (zdevice.c)
|
|
|
|
Changes realtime to match the definition of gp_get_realtime. (zmisc.c)
|
|
|
|
Removes the [.]currenttime operator. realtime provides interval timing in
|
|
milliseconds; the %Calendar% IODevice provides calendar times. (zmisc.c)
|
|
|
|
Extends the LZW filters to handle the PDF Predictor (pixel-differencing)
|
|
option. (zfdecode.c, zfilter2.c, zfpdiff.c (deleted))

- The length of an image's data was sometimes calculated
|
|
incorrectly, causing an error when converting PDF to PostScript.
|
|
(pdf_draw.ps)
|
|
- If word spacing and/or text spacing was non-zero, an error could

</pre><h3><a name="V3.60_Streams"></a>Streams</h3><pre>
|
|
|
|
Fixes bugs:
|
|
- When closing an encoding filter stream whose target was also a
|
|
filter, the latter could get called incorrectly with last = 1, possibly more
|
|
than once, leading to premature EOD markers. (stream.c)
|
|
- The LZW-compatible encoder put out an incorrect end-of-data code.
|
|
(slzwce.c)
|
|
- The LZW-compatible encoder didn't put out a reset code soon
|
|
enough. (slzwce.c)
|
|
- Some `const' declarations were missing. (siscale.c)
|
|
- Doing a sgets on a closed stream could call sreadbuf, possibly
|
|
causing an error. (stream.c)
|
|
|
|
Adds a new (optional) set_defaults procedure to the stream template, which
|
|
sets the stream parameters to default values. We only implement it for a
|
|
few stream types. (scfx.h, scommon.h, slzwx.h, spdiffx.h, srlx.h,
|
|
strimpl.h, scfd.c, scfe.c, slzwce.c, slzwd.c, slzwe.c, spdiff.c, srld.c,
|
|
srle.c)
|
|
|
|
Adds a new parameter to the CCITTFax filters, DecodedByteAlign. This is an
|
|
integer N, which must be a power of 2 between 1 (2^0) and 16 (2^4), that
|
|
specifies that decoded data scan lines are always a multiple of N bytes.
|
|
The encoding filter skips data in each scan line from Columns to the next
|
|
multiple of N bytes; the decoding filter pads each scan line to a multiple
|
|
of N bytes. Default value: 1. (scfx.h, scfd.c, scfe.c)
|
|
|
|
Increases the maximum width of a scan line for the CCITTFaxEncode filter to
|
|
32000 pixels. (scf.h)
|
|
|
|
</pre><h3><a name="V3.60_Library"></a>Library</h3><pre>
|
|
|
|
Fixes bugs:
|
|
- Cached characters sometimes had extra blank space on the left,
|
|
leading to some unnecessary bit-shuffling when imaging them. (gxccman.c)
|
|
- In rare cases, gray halftones called gx_color_load unnecessarily.
|
|
(gxdither.c)
|
|
- The list of all-bands commands wasn't initialized/reset properly.
|
|
(gxclist.c, gxclread.c)
|
|
- Rendering an anti-aliased character to a non-anti-aliased device
|
|
didn't free the temporary bitmap, causing memory to be lost. (gxccache.c)
|
|
- Dash patterns where the offset exactly reached a run of length 0
|
|
skipped over the 0-length run. (gsline.c)
|
|
- Rectangles closed with both lineto and closepath weren't
|
|
recognized as rectangles. This is only a performance bug. (gxpath2.c)
|
|
- Because of a typo in a macro formal parameter list, a private name
|
|
was duplicated. (gsstruct.h)
|
|
- Text display operations didn't update the current character in the
|
|
enumerator structure during the fastest path through the code. This only
|
|
matters to one very unusual commercial client. (gschar.c)
|
|
- Some `const' declarations were missing. (gsparam.h, gxistate.h,
|
|
stdpre.h; gdevm1.c, gsalloc.c, gsfont.c, gsimage3.c, gsmemory.c, gsmisc.c,
|
|
gspcolor.c, gstype1.c, gxfill.c, gxpcopy.c)
|
|
|
|
Changes the header files to assume that gcc on Solaris defines
|
|
__svr4__ and that, in this case, <string.h> has the right stuff in it.
|
|
(memory_.h)
|
|
|
|
Refactors the character cache to share structures with a similar cache
|
|
used by band lists. Eventually the band list may be able to reference
|
|
the character cache directly, saving a lot of copying. (gxbcache.h,
|
|
gxfcache.h, gsfont.c, gxbcache.c, gxccache.c, gxccman.c)
|
|
|
|
Speeds up getting the side bearing and width of a Type 1 charstring a
|
|
little. (gxtype1.h, gstype1.c)
|
|
|
|
Redesigns band lists so that they can cache character bitmaps as well as
|
|
halftone bitmaps. Characters may be written for all bands, not just the
|
|
band(s) they appear in, depending on the setting of the CHAR_ALL_BANDS_COUNT
|
|
parameter in gxclbits.c. (gxcldev.h, gxclist.h, gxclbits.c, gxclist.c,
|
|
gxclread.c)
|
|
|
|
Adds G4 fax compression for band list bitmaps. (gxcldev.h, gxclist.c,
|
|
gxclread.c)
|
|
|
|
Incorporates the new set_defaults procedure into the memory-based band list
|
|
implementation. (gxclmem.c)
|
|
|
|
Implements a halftoning device that can be used in a device pipeline.
|
|
(gdevht.h, gzht.h, gdevht.c, gxcht.c)
|
|
|
|
Factors out imager state from the full graphics state. This division is
|
|
preliminary and subject to change. (gxistate.h, gxop1.h, gzstate.h,
|
|
gsline.c, gsstate.c, gstype1.c, gxhint*.c)
|
|
|
|
Implements passing fill operations in the band list, except for pattern
|
|
color or colored halftones. (gxcldev.h, gxclist.h, gxclist.c, gxclread.c)
|
|
|
|
Implements passing stroke operations in the band list, except for pattern
|
|
color or colored halftones. (gsline.h, gslparam.h, gxline.h, gzline.h,
|
|
gsline.c; gxcldev.h, gxclist.h, gxclist.c, gxclread.c)
|
|
|
|
Implements the ability to represent halftoned characters in the band list.
|
|
(gxccache.c)
|
|
|
|
Starts to implement the ability to do halftoning during the rendering phase
|
|
rather than before writing the band list (currently for black-and-white
|
|
devices only). Doing this required NON-BACKWARD-COMPATIBLE changes to the
|
|
interfaces of a few internal procedures:
|
|
gx_check_tile_size, gx_render_device_{color,gray}
|
|
(gxdcolor.h, gxdht.h, gzht.h, gsht.c, gsimage1.c, gsmisc.c, gspcolor.c,
|
|
gsstate.c, gxcht.c, gxclbits.c, gxdither.c, gxht.c)
|
|
|
|
Implements passing clipping information in the band list. (gzcpath.h,
|
|
gxacpath.c, gxclpath.c, gxclread.c, gxcpath.c)
|
|
|
|
Removes the gs_state * parameter from the device color fill_rectangle
|
|
procedures and many of their callers, since it is no longer needed. This is
|
|
a non-backward-compatible change to an internal API. (gdevmrop.h,
|
|
gxdcolor.h, gxdraw.h, gxpaint.h, gdevmrop.c, gsimage.c, gspcolor.c, gxcht.c,
|
|
gxclread.c, gxdraw.c, gxfill.c, gxht.c, gxpaint.c, gxstroke.c)
|
|
|
|
Removes gxdevice.h from gzstate.h, since not all modules requiring access to
|
|
the graphics state need to know the implementation of devices. This entails
|
|
adding gxdevice.h to the include lists for some modules. (gxchar.h,
|
|
gxcpath.h, gxcvalue.h, gxdevice.h, gxtype1.h, gzstate.h; gschar.c,
|
|
gscoord.c, gsdevice.c, gsimage1.c, gsimage2.c, gsimage3.c, gspaint.c,

gspath.c, gsstate.c, gstype1.c, gxccache.c, gxccman.c, gxhint1.c, gxhint2.c,
|
|
gxhint3.c, gxpaint.c)
|
|
|
|
Adds a compile-time option, ALPHA_LSB_FIRST, which causes alpha-sampled
|
|
characters to be nibble-reversed in the cache. This was created for a
|
|
specialized application and does not interact well with the rest of the
|
|
code. (gsbitops.c)
|
|
|
|
Substantially reduces the space required to represent 24- or 32-bit colors
|
|
in the band list, by using more aggressive color differencing. (gxcldev.h,
|
|
gxclist.c, gxclread.c)
|
|
|
|
Changes the allocation of unique IDs for halftone tiles to use the gray
|
|
level rather than the number of 1-bits as the increment to a base ID; this
|
|
allows more efficient (delta) representation of halftone indices in the band
|
|
list. (gxcldev.h, gxclist.c, gxclread.c, gxht.c)
|
|
|
|
Substantially speeds up entering anti-aliased characters in the cache, by
|
|
removing white space before compressing rather than vice versa.

[3.63] Notes that the OS/2 implementation now requires EMX/GCC 0.9b rather
|
|
than 0.9a. (use.doc)
|
|
|

</pre><h3><a name="V3.53_Procedures"></a>Procedures</h3><pre>
|
|
|
|
Fixes bugs:
|
|
[3.60] The geninit program (the implementation of COMPILE_INITS=1)
|
|
didn't parse the command line properly, and didn't check for PostScript
|
|
files properly. (geninit.c)
|
|
[3.60] ccfontab.c was omitted from the fileset. The easiest way to
|
|
fix this was to rename it to icfontab.c. (gs.mak, int.mak, ccfontab.c)
|
|
[3.60] The definition of pdfread.dev did an ADDMOD, not a SETMOD.
|
|
(int.mak)
|
|
|
|
[3.60] Adds a -dNOFONTPATH switch to suppress any consultation of the

|
producing incorrect spacing and incorrect characters. (pdf_2ps.ps)
|
|
[3.60] ps2ascii left a value on the stack for each unrecognized
|
|
character it processed, eventually causing a stackoverflow. (ps2ascii.ps)
|
|
|
|
[3.61] Changes the rollconv.ps utility to produce files whose names conform
|
|
to the 8.3 length restriction, and to reduce the fixed RAM overhead for
|
|
Kanji fonts. (rollconv.ps)
|
|
|

</pre><h3><a name="V3.53_Drivers"></a>Drivers</h3><pre>
|
|
|
|
Fixes bugs:
|
|
[3.60] Because of a typo, the LaserJet drivers had incorrect
|
|
margins. This was probably a new bug in 3.5x. (gdevdjet.c)
|
|
[3.60] A private name was duplicated. (gdevtfax.c)
|
|
[3.60] The x11alpha driver passed invalid colors to the X library.
|
|
(gdevxalt.c)
|
|
[3.60] The x11alpha driver set the blue component of colors
|
|
incorrectly. (gdevxalt.c)
|
|
|
|
</pre><h3><a name="V3.53_Platforms"></a>Platforms</h3><pre>
|

|
[3.63] The test for WinExec failure on Win32 was incorrect.
|
|
(gp_mswin.c)
|
|
[3.63] getenv was declared redundantly on OS/2. (gp_os2.c)
|
|
[3.63] gs16spl.c was missing <string.h>. (gs16spl.c)
|
|
[3.61] Printing didn't work in 32-bit MS Windows environments.
|
|
(bcwin32.mak, gdevmswn.c, gp_mswin.c)
|
|
[3.61] There were some compatibility problems with IBM C. (os2.mak,
|
|
gsdll.h, gdevpm.c, gp_os2.c)
|
|
[3.60] The printjob created by Ghostscript was called "Ghostscirpt"
|
|
instead of "Ghostscript". (gp_os2.c)
|
|
[3.60] An "export" declaration was omitted from DllInit.
|
|
(gp_mswin.c)
|
|
|
|
[3.61] Adds a conditional to work around a bug in gcc 2.7.x (it didn't
|
|
recognize that the target of a const T * might still be mutable through
|
|
aliasing). (stdpre.h)
|
|
|
|
</pre><h3><a name="V3.53_Fonts"></a>Fonts</h3><pre>
|
|
|
|
Fixes bugs:
|
|
[3.61] Rasterizing a character in a Type 1 font with an invalid
|
|
FontBBox left some garbage on the operand stack (bug introduced in 3.52 or
|
|
3.60). (gs_type1.ps)
|
|
[3.61] The font substitution algorithm could fail or loop.
|
|
(gs_fonts.ps)
|
|
|
|
[3.60] Adds Heavy as a synonym for Bold when doing intelligent font
|
|
substitution. (gs_fonts.ps)
|
|
|
|
</pre><h3><a name="V3.53_Interpreter"></a>Interpreter</h3><pre>
|
|
|
|
Fixes bugs:
|
|
[3.63] Invoking setpagedevice with an undefined key, even with
|
|
Policy = 1, caused an error. (gs_setpd.ps)
|
|
[3.62] Setting the PageSize policy to 1 and then trying to set the
|
|
page size caused an error if FIXEDMEDIA was selected. (gs_setpd.ps)
|
|
[3.61] Rotated characters were rendered incorrectly (bug introduced
|
|
in 3.52). (gstype1.c)
|
|
[3.60] currentscreen and currentcolorscreen could give an error if
|
|
the current screen was set with sethalftone (or, for currentscreen,
|
|
setcolorscreen). (gs_dps1.ps)
|
|
[3.60] Streams could get removed from a bookkeeping list
|
|
prematurely, and wind up dangling. (zfile.c)
|
|
[3.60] Multiple -I switches set the search path incorrectly.
|
|
(gsmain.c)
|
|
[3.60] Fonts could wind up with a pointer to the wrong VM space,
|
|
causing potential GC or save/restore confusion. (zfont2.c)
|
|
[3.60] upath could leave garbage on the stack if it failed.
|
|
(gs_dps1.ps)
|
|
|
|
[3.61] Extends the client API to allow for pushing values onto the operand
|
|
stack. (imain.h, gs.c, gsmain.c)
|
|
|
|
[3.61] Defines a .setdefaultscreen procedure that sets the default halftone
|
|
screen, transfer function, and stroke adjustment for the current device.
|
|
Changes selectdevice and setpagedevice so that they call .setdefaultscreen;
|
|
setpagedevice calls .setdefaultscreen before calling the Install procedure,
|
|
so that Install can set different parameters if it wishes. Note that
|
|
setdevice does not do this. (gs_init.ps, gs_setpd.ps)
|
|
|
|
[3.60] Speeds up rasterizing characters into the cache a little.
|
|
(gs_type0.ps)
|
|
|
|
[3.60] Changes the default limit on the size of cached characters from the
|
|
maximum of (18 points or 5 times the "average" character size) to (18 points
|
|
or 1% of the total cache size). (gs_init.ps)
|
|
|
|
[3.60] Implements parts of the Type 1 BuildChar callout in C. (gs_type1.ps,
|
|
zchar.c)
|
|
|
|
</pre><h3><a name="V3.53_Interpreter_PDF"></a>Interpreter (PDF)</h3><pre>
|
|
|
|
Fixes bugs:
|
|
[3.62] If a PDF file substituted a calibrated color space for the
|
|
DeviceGray or DeviceRGB color space using a ColorSpace resource, the
|
|
PostScript file that pdf2ps produced from that PDF file caused an error.
|
|
(gs_pdf.ps)
|
|
[3.61] Tf set the current text font twice, and interacted with
|
|
pdf2ps in an awkward way. (gs_pdf.ps, pdf_2ps.ps, pdf_font.ps)
|
|
[3.61] If a font had variant Widths, it could get confused in the
|
|
cache with the underlying font. (pdf_font.ps)
|
|
[3.61] If a character appeared twice in an encoding and the font
|
|
specified different Widths values for the two occurrences, the last Width
|
|
would be used. We patched this to ignore zero Widths, which is not the
|
|
correct solution but which almost always produces correct output.
|
|
(pdf_font.ps)
|
|
[3.61] Arrays containing nulls didn't print out correctly (bug
|
|
introduced in 3.60). (gs_init.ps)
|
|
[3.61] Some PDF files contain very large dictionaries, which caused
|
|
a stackoverflow. (pdf_base.ps)
|
|
[3.60] The length of an image's data was sometimes calculated
|
|
incorrectly, causing an error when converting PDF to PostScript.
|
|
(pdf_draw.ps)
|
|
[3.60] If word spacing and/or text spacing was non-zero, an error
|
|
could occur. (gs_pdf.ps)
|
|
[3.60] Text that was both filled and stroked caused an error.
|
|
(gs_pdf.ps)
|
|
|
|
[3.61] Speeds up the initial processing of PDF files by caching the map from
|
|
page numbers to page objects, and by not scanning the outlines if we aren't
|
|
producing PostScript output. (pdf_2ps.ps, pdf_base.ps, pdf_main.ps)
|
|
|
|
</pre><h3><a name="V3.53_Streams"></a>Streams</h3><pre>
|
|
|
|
Fixes bugs:
|
|
[3.60] When closing an encoding filter stream whose target was also
|
|
a filter, the latter could get called incorrectly with last = 1, possibly
|
|
more than once, leading to premature EOD markers. (stream.c)
|
|
[3.60] The LZW-compatible encoder put out an incorrect end-of-data
|
|
code. (slzwce.c)
|
|
[3.60] The LZW-compatible encoder didn't put out a reset code soon
|
|
enough. (slzwce.c)
|
|
[3.60] Doing a sgets on a closed stream could call sreadbuf,
|
|
possibly causing an error. (stream.c)
|
|
|
|
</pre><h3><a name="V3.53_Library"></a>Library</h3><pre>
|
|
|
|
Fixes bugs:
|
|
[3.63] On 16-bit platforms, the computation of t2 and t3 in
|
|
gx_curve_x_at_y could overflow, leading to incorrect output. (gxpcopy.c)
|
|
[3.61] glyphshow displayed a character with code 0 rather than the
|
|
requested character (bug introduced in 3.60.) (gschar.c)
|
|
[3.61] If trimming white space around a character reduced its
|
|
raster, the character was garbled in the cache (bug introduced in 3.60.)
|
|
(gxccman.c)
|
|
[3.61] colorimage would incorrectly convert white pixels to black if
|
|
the image color space was CMYK, the current color space was not CMYK, and
|
|
the number of bits per pixel was 4 or 8. (gsimage2.c)
|
|
[3.61] Type 1 fonts that used the Flex feature applied hints to the
|
|
path multiple times, causing dropouts, uneven stems, and other problems (bug
|
|
probably introduced in 3.21). (gstype1.c)
|
|
[3.61] If a Type 1 font used the Flex feature within the accent of
|
|
an accented character defined with seac, the shape of the accent could be
|
|
distorted. (gxtype1.h, gstype1.c)
|
|
[3.61] If a Type 1 font changed hints using the hint replacement
|
|
facility when the last operation was a closepath, the old hints would be
|
|
applied a second time, distorting the shape. (gxhint2.c, gxhint3.c)
|
|
[3.60] Cached characters sometimes had extra blank space on the
|
|
left, leading to some unnecessary bit-shuffling when imaging them.
|
|
(gxccman.c)
|
|
[3.60] The list of all-bands commands wasn't initialized/reset
|
|
properly. (gxclist.c)
|
|
[3.60] Because of a typo in a macro formal parameter list, a private
|
|
name was duplicated. (gsstruct.h)
|
|
[3.60] Text display operations didn't update the current character
|
|
in the enumerator structure during the fastest path through the code. This
|
|
only matters to one very unusual commercial client. (gschar.c)
|
|
|
|
[3.61] Adds an alternative implementation of the core path filling algorithm
|
|
that is much faster on objects with curves but doesn't handle Y fattening.
|
|
This is the implementation that will normally be used for rasterizing
|
|
characters. This implementation rasterizes curves directly, without
|
|
flattening them. (gxfixed.h, gxpath.h, gzpath.h, gxdraw.c, gxfill.c,
|
|
gxpcopy.c)
|
|
|
|
[3.61] Speeds up the flattening of curves substantially by omitting more
|
|
redundant points. (gxpcopy.c)
|
|
|
|
[3.61] Speeds up character bitmap compression a little more. (gsbitops.h,
|
|
gdevabuf.c, gsbitops.c, gxccman.c)
|
|
|
|
[3.61] Speeds up anti-aliased graphics a bit by computing a bounding box
|
|
before converting from oversampling to alpha values, and by speeding up the
|
|
bounding box computation itself. (gsbitops.h, gdevabuf.c, gsbitops.c,
|
|
gxccman.c)
|
|
|
|
[3.60] Speeds up getting the side bearing and width of a Type 1 charstring a
|
|
little. (gxtype1.h, gstype1.c)
|
|
|
|
[3.60] Adds a compile-time option, ALPHA_LSB_FIRST, which causes
|
|
alpha-sampled characters to be nibble-reversed in the cache. This was
|
|
created for a specialized application and does not interact well with the
|
|
rest of the code. (gsbitops.c)
|
|
|
|
[3.60] Substantially speeds up entering anti-aliased characters in the
|
|
cache, by removing white space before compressing rather than vice versa.

Fixes bugs:
|
|
- The PC display devices weren't page devices. Probably all the
|
|
other display and window system devices should be made page devices too, but
|
|
we aren't going to bother tracking them down. (gdevpcfb.c)
|
|
- There was a lot of duplicated code in the TIFF drivers.
|
|
(gdevtifs.h, gdevtfax.c, gdevtfnx.c, gdevtifs.c)

|
|
Fixes bugs:
|
|
- Building with COMPILE_INITS=1 produced a stackunderflow error.
|
|
(gs_pdf_e.ps)
|
|
- An internal operator didn't have a name. (ztoken.c)
|
|
- Some error and information messages weren't in the Adobe format.
|
|
(gs_fonts.ps, gs_init.ps)
|
|
- Some common Adobe compatibility operators weren't implemented:
|
|
pagemargin, pageparams, setpagemargin. (gs_statd.ps, gs_lev2.ps)
|
|
- setpageparams set Margins rather than PageOffset. (gs_lev2.ps)
|
|
- setpage and setpageparams didn't set Orientation. (gs_lev2.ps)
|
|
- If the end of an input buffer fell just after the / of a literal
|
|
name, a memory access error could occur. (iscan.c)
|
|
- When the interpreter returned from gs_[main_]run_string_continue,
|
|
there could be an extra value on the operand stack. (iscan.h, istream.h,
|
|
interp.c, iscan.c, zfileio.c, zfproc.c, zpaint.c, ztoken.c)
|
|
- If the character cache was disabled, or if a character was too
|
|
large to be cached, returning from a font BuildChar procedure could do an
|
|
erasepage. (zchar.c)
|
|
|
|
A minor change was required for compatibility with the library change for
|
|
image devices. (zdevice.c)
|
|
|
|
Adds a -dSHORTERRORS switch that changes some of the common error and
|
|
warning messages for greater Adobe compatibility. (gs_init.ps, gs_fonts.ps)

|
|
|
</pre><h3><a name="V3.50_Interpreter_PDF"></a>Interpreter (PDF)</h3><pre>

Fixes bugs:
|
|
- If a CharProc for a Type 3 font did a BT/ET, the graphics state
|
|
could get confused. (gs_pdf.ps)
|
|
- If a Tf occurred inside a BT/ET, it didn't take effect on
|
|
subsequent BT/ETs. (gs_pdf.ps)
|
|
|
|
</pre><h3><a name="V3.50_Library"></a>Library</h3><pre>
|
|
|
|
Fixes bugs:
|
|
- There was no way to control whether an image device was a page
|
|
device. Fixing this required a NON-BACKWARD-COMPATIBLE CHANGE to
|
|
gs_makewordimagedevice and gs_initialize_wordimagedevice to take a Boolean
|
|
page_device argument. Fortunately, this change affects only a few obscure
|
|
library clients. (gsdevice.h, gsdevmem.c)
|
|
|
|
Adds translation capability to clipping devices. This isn't used anywhere
|
|
yet. (gxcpath.h, gxcpath.c)
|
|
|
|
Adds procedures for doing unaligned copy_xxx operations. These were added
|
|
for a customer. (gxdevice.h, gsdevice.c)
|
|
|
|
Changes the (undocumented) return value of gs_setcachedevice[2]: they used
|
|
to return 1 if the current show operation was a non-displaying one
|
|
(stringwidth or cshow), and now return 1 if the cache device was just
|
|
installed. This change was required to fix the BuildChar page clearing bug
|
|
in the interpreter. THIS IS A NON-BACKWARD-COMPATIBLE CHANGE, but as far as
|
|
I know, there aren't any external clients of these routines. (gschar.h,

|
this release, we implement only a subset, and without handling transparency
|
|
properly.) (gdevm2.c, gdevm4.c, gdevmrop.c)

|
- Severely non-linear CIE encoding/decoding functions produced

seriously skewed colors near the ends of the color value range. This

problem can now be alleviated, at a significant cost in performance, by
|
|
changing configuration parameters at the beginning of gscie.h. (gscie.h,

|
|
- A 1-D CCITTFaxDecode stream could give an error if an input buffer
|

boundary fell just before a 0-length termination code. (scfx.h, scfd.c)
|

|
|
</pre><h3><a name="V3.45_Library"></a>Library</h3><pre>
|

|
Fixes bugs:
|
|
- A variable was used before being set, which could cause band
|
|
devices to become confused when processing colored halftones. (gxclist.c)
|
|
- Some of the color and tile bookkeeping for band lists was wrong
|
|
(as of 3.44), causing tiled areas to be filled with garbage. (gxclist.c,
|
|
gxclread.c)
|
|
- Colored Patterns showed up blank on devices whose native
|
|
representation of `black' was a non-zero value. The fix removes the
|
|
'cached' member of the gx_device structure, and requires monobit memory
|
|
devices to have a palette; this is a NON-BACKWARD-COMPATIBLE CHANGE for
|
|
anyone who was foolish enough to statically initialize a gx_device structure
|
|
without using the macros in gxdevice.h or gdevprn.h. (gdevmem.h,
|
|
gxdevice.h, gxdevmem.h, gdevm1.c, gdevmrop.c, gsdevice.c, gxcpath.c,

Provides the framework for band devices to implement alpha (anti-aliasing).
|
|
(gxcldev.h, gdevprn.c, gsdevice.c, gxclist.c, gxclread.c)
|
|
|
|
Implements an efficient API for enumerating paths using device coordinates.
|
|
(gspath.h, gxpath.h, gzpath.h, gspath1.c, gxpath2.c)
|
|
|
|
Changes the character cache logic so that when rasterizing large
|
|
anti-aliased characters, it converts the oversampled bits to alpha values on
|
|
the fly rather than waiting until it has rasterized the entire character.
|
|
This saves a lot of temporary space, at the expense of some extra time and
|
|
lower quality results for Type 3 characters that don't use a single fill or
|
|
imagemask operation to draw the character. This enhancement requires adding
|
|
a member to the gx_device structure (max_fill_band), which is a
|
|
NON-BACKWARD-COMPATIBLE CHANGE for badly written drivers (see above).
|
|
(gxchar.h, gxdevice.h, gxpaint.h, gdevabuf.c, gschar.c, gspaint.c,
|
|
gxccache.c, gxccman.c, gxfill.c)
|
|
|
|
Changes the palette member of memory devices from gs_string to
|
|
gs_const_string. (gdevmem.h, gxdevmem.h, gdevmem.c, gdevm1.c)
|
|
|
|
Starts to decouple halftoning from the graphics state machinery, so
|
|
it can be applied after banding rather than before. (gxdcolor.h,
|
|
gxdht.h, gxdither.h, gzht.h, gxcmap.c, gxdither.c, gxdraw.c)
|
|
|
|
Starts to decouple path filling from the graphics state machinery, so
|
|
that we can pass paths through band lists. (gxpaint.h, gxfill.c)
|
|
|
|
Adds interpolation to the CIE RenderTable lookup. This is optional, enabled
|
|
by #define CIE_RENDER_TABLE_INTERPOLATE in gscie.h. (gscie.h, gxctable.h,

gscie.c, gxctable.c)

Adds the requirement that all page-oriented devices (i.e., those that use

gdevprn.h and implement the print_page procedure) include page.dev in their
|
|
dependencies and use $(SETPDEV) rather than $(SETDEV) in their makefile rule
|
|
bodies. THIS IS A NON-BACKWARD-COMPATIBLE CHANGE. Without this change, the

included in every configuration. (gs.mak, devs.mak, echogs.c)

Adds a user-contributed driver for the Okidata Microline (IBM compatible)
|

- CIE color conversion didn't work on 16-bit systems. (gscie.h,
|
|
gscie.c)
|
|
|
|
Partially implements reducing the intermediate space for rasterizing
|
|
anti-aliased characters by compressing the oversampled representation to an
|
|
alpha array incrementally. (gdevmem.h, gxchar.h, gxdevmem.h, gdevabuf.c,
|
|
gschar.c, gspaint.c, gxccman.c)
|
|
|
|
Starts adding support for the new CIEBasedDEF and CIEBasedDEFG color spaces.
|
|
(gscie.h, gscspace.h, gscie.c)
|
|
|
|
Completes the implementation of band lists in RAM. To select this feature,
|
|
change the definition of cl_impl in gs.mak from clfile to clmem. (Someday
|
|
we'll make this easier.) (gxclmem.h, gxclmem.c)
|
|
|
|
Finishes implementing RasterOp and transparency at the driver level for
|
|
monobit and 8-bit gray-scale devices, and implements some of the framework
|
|
for general multiple-bit-per-pixel devices. See drivers.doc for
|
|
documentation. (gsropt.h, gxcldev.h, gxclist.h, gdevm1.c, gdevm8.c,
|
|
gdevmem.c, gdevmrop.c, gschar.c, gxclist.c, gxclread.c)
|
|
|
|
Implements the ability to include commands applicable to all bands, rather
|
|
than an individual band, in the band list. Eventually this will be used for
|
|
passing halftones through the band list. (gxcldev.h, gxclist.h, gxclist.c)
|
|
|
|
Adds support for 2-bit-deep 'word' memory devices. (gdevmem.h, gxdevmem.c,
|
|
gdevm2.c)
|
|
|
|
Changes the initialization for memory devices so that they determine their
|
|
polarity from the device for which they are buffering the image (if any).
|
|
This is a subtle change. (gdevmem.h, gdevmem.c, gdevm1.c, gsdevmem.c)

|
unixtail.mak, echogs.c, genarch.c, genconf.c, geninit.c)
|
|
|
|
Reinstates FEATURE_DEVS in the makefiles, getting rid of FEATURE1..10. THIS
|
|
IS A NON-BACKWARD-COMPATIBLE CHANGE, but it puts things back the way they
|
|
were before 3.41, with one exception: compiling the PostScript
|
|
initialization code into the executable is now a separate macro
|
|
COMPILE_INITS with a definition of 0 or 1, instead of the ccinit 'feature'.
|
|
(gs.mak, *.mak, fonts.doc, make.doc)
|
|
|
|
Adds a CCLEAF macro to the makefiles, for optimizing the compilation of
|
|
modules containing only leaf procedures. (gs.mak, *.mak)

operator in userdict, rather than as an operator in systemdict. This caused
|
|
a noaccess error when loading certain Type 1 fonts. (gs_init.ps,

|
|
- The coordinate computations for all filling operations were
|
|
slightly inaccurate, leading to pixel 'holes' in rotated images. (gxdda.h,
|
|
gximage.h, gsimage*.c, gxdraw.c, gxfill.c)
|
|
|
|
Undoes an "optimization" (inlining the normal, fast case of a procedure)
|
|
that actually hurt performance. (gxclist.c)
|
|
|
|
Refactors the command list code so that it in the future it will be able to
|
|
store command lists either in RAM or in the file system. (gdevprn.h,
|
|
gxcldev.h, gxclio.h, gxclist.h, gdevprn.c, gxclfile.c, gxclist.c,
|
|
gxclread.c)
|
|
|
|
Changes the interface to the path filling code to take separate X and Y
|
|
adjustment values. (gxpaint.h, gspaint.c, gxfill.c)
|
|
|
|
Makes the command list allocate a small tile cache if the device doesn't
|
|
need halftones. (gxclist.c)

(suspendable string input in particular) to commercial customers, and with a
|
|
few bug fixes.
|
|
|
|
<h3><a name="V3.39_Documentation"></a>Documentation</h3><pre>
|

Notes that PDF files and repositioning PostScript files do not work if
|
|
Ghostscript was compiled with VAX C. (use.doc)
|
|

Notes the requirement for EOD lookahead in decoding filters. (strimpl.h)
|
|
|
|
</pre><h3><a name="V3.39_Procedures"></a>Procedures</h3><pre>

- There were a number of undefined or used-before-defined variables
|
|
in the makefiles. (devs.mak, dvx-head.mak, unixhead.mak, gs.mak)
|
|
- Some commands in the makefile exceeded the MS-DOS limit of 120
|
|
characters. (gs.mak)
|
|
|
|
Adds a -P and -P- switch to control whether the search path automatically
|
|
includes `.' as its first element. Moves the default value of this choice
|
|
(SEARCH_HERE_FIRST) from gsmain.c to iminst.h. (iminst.h, gs.c, gsmain.c,
|
|
use.doc)
|

Makes some makefile changes in anticipation of the IJG v6 release. (*.mak)
|
|
|
|
</pre><h3><a name="V3.39_Utilities"></a>Utilities</h3><pre>

|
|
(zrelbit.c)
|
|
- An include was missing. (zcsindex.c)
|
|
- .forgetsave at the outermost level didn't reset the l_new flag in
|
|
changed slots, leading to an anomalous (although perhaps not harmful) state.
|
|
(isave.c)
|
|
- Dictionary growing or unpacking would both save and free the old
|
|
keys array, leading to a dangling reference. (idict.c)
|
|
|
|
Changes gs_interpret so that for .quit with a negative operand <= -100,
|
|
gs_interpret returns e_Fatal rather than the operand. THIS IS A
|
|
NON-BACKWARD-COMPATIBLE CHANGE, but as far as we know, it doesn't affect
|
|
anyone. (interp.c)
|
|
|
|
Adds an API to allow feeding string input to the interpreter in pieces.
|
|
(errors.h, imain.h, main.h, gs.c, gsmain.c, interp.c, zcontrol.c, zfilter.c)
|
|

Adds new predicates .identeq and .identne that test "pointer equality", even
|
|
for numbers and strings. (iutil.h, iutil.c, zrelbit.c)
|
|
|
|
Changes a few uses of return_error to return in places that don't lead
|
|
directly to a PostScript error. (idict.c)
|
|
|
|
</pre><h3><a name="V3.39_Streams"></a>Streams</h3><pre>
|
|
|
|
Fixes bugs:
|
|
- The logic for skipping up to a 0xff byte when decoding JPEG data
|
|
could skip too much. (sdctd.c, sjpegd.c)
|
|
- If a buffer boundary fell in the middle of, or just before, an
|
|
EOD, some decoding filters could stop reading too soon. (sbcp.c, smtf.c,

- The library initialization/termination API wasn't declared.
|
|
(gslib.h, gsinit.c, gsmain.c)
|

<h2><a name="Version3.38"></a>Version 3.38 (limited) (6/18/95)</h2>
|
|
|
|
<p>
|
|
This release incorporates several customer-requested enhancements (cleaner
|
|
separation of the graphics library from the interpreter, option for >64K
|
|
names, true garbage collection of names, better handling of halftones on
|
|
band devices). It is intended primarily for those customers, but is
|
|
intended as a dry run for the next public release.

|
|
|
<h3><a name="V3.38_Documentation"></a>Documentation</h3><pre>

|
</pre><h3><a name="V3.38_Procedures"></a>Procedures</h3><pre>
|
|
|
|
Fixes bugs:
|
|
- The man page extension in the Unix makefiles was still $(manext),
|
|
not $(man1ext). (unix-end.mak)
|
|
- 'make clean' didn't remove gs_init.c. (gs.mak)
|
|
|
|
Restructures the makefiles to better separate the language interpreters from
|
|
the graphics core. (gs.mak)
|
|
|
|
Adds a -dNOPROMPT switch to suppress the end-of-page prompts (but still wait
|
|
for the user to type a newline). This is different from -dNOPAUSE, which
|
|
suppresses both the prompts and the wait. (gs_init.ps)
|
|
|
|
</pre><h3><a name="V3.38_Utilities"></a>Utilities</h3><pre>
|
|
|
|
Replaces the mergeini.ps program with an equivalent (actually slightly
|
|
better) version written in C. (gs.mak, *.mak, psfiles.doc, use.doc,
|
|
geninit.c)
|
|
|
|
</pre><h3><a name="V3.38_Drivers"></a>Drivers</h3><pre>
|
|
|
|
Fixes bugs:
|
|
- The color DeskJet drivers wouldn't compile with a K&R compiler,
|
|
because some of the procedure definitions weren't in the restricted syntax
|
|
that ansi2knr requires. (gdevcdj.c)
|
|
- The color DeskJet drivers wouldn't compile because of a bug in
|
|
Sun's cc. (gdevcdj.c)
|
|
|
|
Changes the BJ-10e(x) margins to be identical to those of the BJ-200.
|
|
(gdevbj10.c)
|
|
|
|
Changes the LaserJet margins in response to a user's request. (gdevdjet.c)
|
|
|
|
Changes the psmono driver to produce slightly larger files that execute
|
|
faster on typical Level 1 printers. (gdevpsim.c)
|
|
|
|
Changes the psmono driver so that it does not scale the image to fit the
|
|
page size, but instead scales it to be the same physical size on the page.
|
|
THIS IS A NON BACKWARD COMPATIBLE CHANGE. However, for full-page images, it
|
|
will not have any visible effect. (gdevpsim.c)
|
|
|
|
</pre><h3><a name="V3.38_Platforms"></a>Platforms</h3><pre>
|
|
|
|
Fixes bugs:

- The IBM RS/6000 needs both <time.h> and <sys/time.h>. (time_.h)
|
|
|
|
Adds the PDF interpreter to the standard MS Windows configuration.
|
|
(bcwin.mak)
|
|
|
|
</pre><h3><a name="V3.38_Fonts"></a>Fonts</h3><pre>
|
|
|
|
Fixes bugs:
|
|
- The entry for Courier-BoldItalic in cfonts.mak incorrectly named
|
|
it as Courier-Italic. (cfonts.mak)
|
|
- The files for Courier-Italic in cfonts.mak were inconsistently
|
|
named ncrri instead of ncri. (cfonts.mak)
|
|
- The rules in cfonts.mak covered only the fonts distributed with
|
|
the free versions of Ghostscript, omitting some of the standard set of 35.
|
|
(cfonts.mak)
|
|
- The maximum number of stem hints per character in Type 1 fonts
|
|
wasn't large enough for complex Asian characters. (gxtype1.h)
|
|
|
|
Adds a -dNOFONTMAP switch to suppress loading the Fontmap file.
|
|
(gs_init.ps, gs_fonts.ps)
|
|
|
|
</pre><h3><a name="V3.38_Interpreter"></a>Interpreter</h3><pre>
|
|
|
|
Fixes bugs:
|
|
- One of the GC marking routines for halftones had a typo,
|
|
possibly leading to an invalid access. (zht2.c)
|
|
- The GC could store beyond the end of the mark stack,
|
|
possibly smashing some characters of a string or name. (igc.c)
|
|
- If the allocator allocated a new ref object from a
|
|
freelist, the bookkeeping for the current ref object could get
|
|
confused. (ialloc.c)
|
|
- The GC didn't remove names properly from the hash table.
|
|
(iname.c)
|
|
- If a DOS editor added a ^Z to the end of an initialization file,
|
|
an error occurred during initialization. (gs_init.ps)
|
|
- If an initialization file had any lines longer than 128
|
|
characters, .skipeof would get an error. (gs_init.ps)
|
|
- makepattern could create structures in global VM pointing to
|
|
structures in local VM. (zpcolor.c)
|
|
- The default color rendering dictionary didn't specify large enough
|
|
ranges for some intermediate values. (gs_lev2.ps)
|
|
- Files being freed by a restore weren't unlinked properly, leading
|
|
to dangling pointers. (zfile.c)
|
|
- The interpreter used strlen without a prototype. (interp.c)
|
|
- Indexed or Separation colors with a CIE base or alternate space
|
|
didn't work. (zcie.c)
|
|
- The Watcom C 10.0 compiler produced incorrect code for an
|
|
overlapping structure assignment. (zcsindex.c)
|
|
|
|
Removes limit of 64K names, if EXTEND_NAMES is defined at compile
|
|
time. (*.mak, idebug.h, iminst.h, iname.h, gs.c, gsmain.c, idebug.c,
|
|
iname.c)
|
|
|
|
Makes the garbage collector really collect names. (iname.h, inamedef.h,
|
|
isstate.h, igc.c, iname.c, isave.c)
|
|
|
|
Restructures some files to better separate the language interpreters
|
|
from their support code. (gconfig.c, iconfig.c, iinit.c)
|
|
|
|
Restructures some files to better separate the language interpreters
|
|
from the graphics core. (iastate.h, iastruct.h, ialloc.c)
|
|
|
|
Allows the operands of cshow to be in either order on the stack. Adobe
|
|
interpreters apparently allow this, even though it's not documented.
|
|
(zchar2.c)
|
|
|
|
Adds a hack in cvs to truncate non-standard operator names, rather than
|
|
giving a rangecheck, to work around the "max err string" problem in some
|
|
common error handlers. (ztype.c)
|
|
|
|
Changes the print string for unregistered operators from operator_0x... to
|
|
@0x.... (iutil.c)
|
|
|
|
Changes the garbage collector so it tries to allocate a large mark stack, to
|
|
avoid going into its 'slow' mode if the mark stack overflows. (igc.c)
|
|
|
|
</pre><h3><a name="V3.38_Interpreter_PDF"></a>Interpreter (PDF)</h3><pre>
|
|
|
|
Fixes bugs:
|
|
- Stroked text used the text matrix, rather than just the
|
|
CTM, for scaling the line width, which could lead to inappropriately
|
|
wide lines. (gs_pdf.ps)
|
|
- Fonts based on other than a 1000-unit scale (i.e., with a
|
|
FontMatrix other than [0.001 0 0 0.001 0 0]) didn't scale Widths to
|
|
match the font scaling. (pdf_font.ps)
|
|
|
|
Implements the PDF 1.1 color space extensions, except for Lab space.
|
|
(gs_pdf.ps, pdf_draw.ps)
|
|

Implements the Rotate key for pages. (pdf_main.ps)
|
|
|
|
</pre><h3><a name="V3.38_Streams"></a>Streams</h3><pre>
|
|
|
|
Fixes bugs:
|
|
- When the garbage collector closed a file stream, the stream
|
|
incorrectly attempted to free the buffer. (stream.c)
|
|
|
|
Separates out some stream implementations to better distinguish the
|
|
graphics core from the language interpreters. (smtf.h, sfilter1.c,
|
|
smtf.c, srld.c, srle.c)
|
|
|
|
</pre><h3><a name="V3.38_Library"></a>Library</h3><pre>
|
|
|
|
Fixes bugs:
|
|
- Compressing characters being entered in the cache could cause an
|
|
invalid memory access. (gsbitops.c)
|
|
- The setbbox bounding box check was slightly inaccurate.
|
|
(gsdps1.c)
|
|
- makepattern could create structures in global VM pointing to
|
|
structures in local VM. (gscolor2.h, gspcolor.c)
|
|
- Out-of-range values during CIE color conversion led to random
|
|
results. (gscie.c)
|
|
- On output devices with non-inverted Y axes (such as MS Windows),
|
|
Interpolated images would smash memory. (gsimage.c)
|
|
- 90 degree rotated zero-width images caused an invalid memory
|
|
access. (gsimage1.c)
|
|
- If #copies was zero, showpage could create bogus empty output
|
|
files. (gdevprn.c)
|
|
- PageCount didn't take #copies into account. (gsdevice.c)
|
|
- Indexed or Separation colors with a CIE base or alternate space
|
|
didn't work. (gscie.h, gscie.c)
|
|
|
|
Implements triangular line caps and joins, in anticipation of adding
|
|
a PCL5 interpreter. (gsline.h, gxstroke.c)
|
|
|
|
Moves some procedures around for better separation of library from
|
|
interpreter. (gsinit.c, gslib.c, gsmain.c, gsmisc.c)
|
|
|
|
Moves the standard allocator from the interpreter to the library.
|
|
(gsalloc.h, gxalloc.h, gxobj.h, gsalloc.c)
|
|
|
|
Starts to change the representation of paths slightly to make it possible to
|
|
identify arcs. This change is backward-compatible for all code except
|
|
callers of gx_path_add_arc. (gxpath.h, gspath1.c, gxpath.c, gxstroke.c)
|
|
|
|
Adds some framework for keeping track of RasterOp and "transparency" in the
|
|
graphics state, although these don't actually have any effect yet.
|
|
(gsrop.h, gsropt.h, gsstate.h, gxcldev.h, gzstate.h, gsrop.c, gsstate.c,
|
|
gxclist.c, gxclread.c)

|
|
|
Adds a compile-time option for using the Adobe RGB<->CMYK conversion rules.
|
|
(gxdcconv.c)
|
|
|
|
Adds a driver procedure for identifying band devices. This change is
|
|
backward-compatible for all existing devices. (gdevmem.h, gxdevice.h,
|
|
gsdevice.c, gxclip2.c, gxclist.c, gxcpath.c)
|
|
|
|
Speeds up gray-scale images on devices requiring banding, and enables
|
|
further optimizations, by reintroducing the distinction between banded and
|
|
non-banded devices. (gxdevice.h, gdevprn.c, gsimage1.c)
|
|
|
|
Reduces the size of the band list for halftoned images by encoding tile
|
|
indices more compactly. (gxcldev.h, gxclist.h, gxclist.c, gxclread.c)
|
|
|
|
Extends the band list so it can cache more than 256 halftone tiles, and to

- The black-and-white H-P printers didn't close the printer
|
|
properly, causing printing not to happen under MS Windows. (gdevprn.c)
|
|
- Some compilers didn't like initializing a const char * to NULL.
|
|
(gdevlbp8.c)
|
|
|
|
Changes the X Windows driver so that if Ghostview specifies a bounding box,
|
|
this also sets ImagingBBox. (gdevxini.c)
|
|
|
|
At the request of a customer, adds 1-, 4-, 8-, 24-, and 32-bit-deep memory

|
caused an error. (iscanbin.c)
|
|
|
|
Adds a LOCALFONTS switch that causes Ghostscript to load Type 1 fonts into

|
the current VM, rather than global VM. According to Adobe, this is what

Fixes bugs:
|
|
- The fax and TIFF drivers didn't free all their working storage.
|
|
(This bug was fixed in 3.27, and the fix somehow got lost.) (gdevtfax.c)
|
|
|
|
Adds new drivers:
|
|
- sgirgb, to produce SGI RGB raster files. (gdevsgi.c)
|
|
- tiffcrle, to produce output in TIFF "CCITT 1-dimensional Huffman
|
|
RLE" format (Group 3 fax with no EOLs). (gdevtfax.c)
|
|
- tifflzw, to produce output in TIFF LZW format (using the existing
|
|
CCITTFaxEncode filter code). (gdevtfax.c)
|
|

|
|
|
|
</pre><h3><a name="V3.30_Interpreter_PostScript"></a>Interpreter (PostScript)</h3><pre>
|
|
|
|
Fixes bugs:
|
|
- If the current screen was set with a halftone, setcolorscreen
|
|
wouldn't accept what currentcolorscreen returned. (gs_dps1.ps)
|
|
- debug_print_full_ref didn't print t_oparray objects correctly.
|
|
(idebug.c)
|
|
- The internal data for a font could be allocated in a different VM
|
|
space from the font dictionary, causing dangling pointers. (zfont2.c)
|
|
- definefont became confused if a program failed to delete the FID
|
|
from a re-encoded font. (This is questionable PostScript, but dvips does
|
|
it.) (zfont2.c)
|
|
- If a BuildChar procedure did a save before the setcachedevice and
|
|
a restore afterwards, the memory manager would attempt to free the cache
|
|
device after it had already been freed by the restore, leading to damaged
|
|
freelists. (gschar.c)
|
|
- setresolution (in statusdict) was ignored. (gs_lev2.ps,
|
|
gs_statd.ps)
|
|
- If a string containing a string containing a \ was passed to the
|
|
token operator, the \ was not recognized properly in a Level 2 environment.
|
|
(iscan.c)
|
|
- A couple of default dictionary sizes had become too small.
|
|
(iinit.c)
|
|
|
|
Makes DOS EOF (control-Z, 0x1a) a self-delimiting token, like left bracket.
|
|
THIS IS A NON-BACKWARD-COMPATIBLE CHANGE, but it should not have any adverse
|
|
effects. (gs_init.ps, iscan.c, iscantab.c)
|
|
|
|
Distinguishes arch_small_memory from arch_ints_are_short, and adds a new
|
|
-Z. switch to force small-memory table sizes regardless of actual memory
|
|
size. (dstack.h, idict.c, zpcolor.c, zvmem2.c)
|
|

|
|
- Executing a Form resource caused an error. (pdf_draw.ps)
|
|
- Outlines with open entries caused an error. (pdf_main.ps)
|
|
- Embedded Type 3 fonts caused an error. (pdf_draw.ps, pdf_font.ps)
|

- The Widths array of fonts was ignored. (pdf_font.ps)
|
|
|
|
</pre><h3><a name="V3.30_Library"></a>Library</h3><pre>
|
|
|
|
Fixes bugs:
|
|
- Freeing an entry in the pattern cache didn't clear the pointers to
|
|
the raster data, producing a dangling reference that confused the garbage
|
|
collector. (gxpcmap.c)
|
|
- The test on FORCE_HINTS_TO_BIG_PIXELS was backwards. (gstype1.c)
|
|
- The pattern cache bookkeeping was incorrect. (gxpcmap.c)
|
|
- Depending on the order in which pointers were relocated, the
|
|
garbage collector could incorrectly relocate pointers from the character
|
|
cache. (gxfcache.h, gsfont.c, gxccache.c, gxccman.c)
|
|
|
|
Changes the fast case of black-and-white images so it aligns scaled images
|
|
with the device coordinate system, to improve performance. (gsimage1.c)
|
|
|
|
Extends the coordinate transformation routines to handle absurdly large
|
|
translation values in the CTM as long as the final device device coordinates
|
|
are within fixed-point range. (gxmatrix.h, gxpath.h, gschar.c, gscoord.c,
|
|
gsmatrix.c, gxhint2.c, gxpath2.c)
|
|
|
|
Distinguishes arch_small_memory from arch_ints_are_short, and adds a new
|

Another bug-fix release. This release processes all but 7 of the 500+ files
|
|
on the Adobe Acrobat Sampler CD-ROM without giving an error. The garbage
|
|
collector finally appears to be stable. This version was created for a
|
|
customer; it was not released to the general public or even to the beta test
|

</pre><h3><a name="V3.29_Drivers"></a>Drivers</h3><pre>
|
|
|
|
Fixes bugs:
|
|
- The top margin for printer (and fax) devices was computed
|
|
incorrectly, using the X resolution rather than the Y resolution.
|
|
(gdevprn.h)
|
|
- Changing the page size or resolution of a printer device closed
|
|
and reopened the device unnecessarily. (gdevprn.c)
|
|
- Changing the page size of the X11 device didn't change the initial
|
|
matrix, so (0,0) didn't wind up in the lower left corner. (gdevx.c)
|
|
- The bit devices didn't allow changing the number of bits per
|
|
pixel. (gdevbit.c)
|
|
|
|
Adds a settable .IsPageDevice boolean device parameter to the X Windows
|
|
driver. The default value is true. (gdevx.h, gdevx.c)
|
|
|
|
Changes the PPM driver so that it chooses between PBM/PGM/PPM on a
|
|
page-by-page basis, rather retaining the most general format ever required
|
|
by any page. (gdevpbm.c)
|
|
|
|
</pre><h3><a name="V3.29_Interpreter_PostScript"></a>Interpreter (PostScript)</h3><pre>
|
|
|
|
Fixes bugs:
|
|
- The current page device could be null, rather than an empty
|
|
dictionary. (igstate.h, zchar.c, zdevice.c, zdevice2.c, zgstate.c)
|
|
- The scanner didn't signal an error for names or strings that were
|
|
too long. (iscan.c)
|
|
- A missing header file upset the VAX compilers. (ztype.c)
|
|
- Some places expecting dictionary operands didn't check the type,
|
|
because they incorrectly assumed that the dict_check_read/write macro did
|
|
this. (idict.h, zdevice2.c, zht2.c, zmisc2.c)
|
|
- The definition of quit in systemdict wasn't disabled within
|
|
encapsulated jobs. (gs_lev2.ps)
|
|
- resetfile gave an error if the file was closed, rather than doing
|
|
nothing. (zfileio.c)
|
|
- The scanner attempted to free an uninitialized pointer if it
|
|
reached EOF after a / or //. (iscan.c)
|
|
- A restore in a different file than the corresponding save caused
|
|
an invalidrestore error. (gs_init.ps)
|
|
- The default value of EndOfData in RunLengthDecode streams was set
|
|
to false. (zfilter.c)
|
|
- .registerencoding didn't invoke the save machinery correctly,
|
|
leading to GC problems. (zfont2.c)
|
|
- The facility for overriding .printerror didn't work correctly.
|
|
(gs_init.ps)
|
|
- gs_run_file_open wasn't public. (gsmain.c)
|
|
- The interpreter returned e_undefined for undefined error names,
|
|
rather than the error code. (interp.c)
|
|
- Allocation in system memory (specifically, adding a block to a
|
|
stack) couldn't trigger automatic garbage collection. (interp.c, igc.c,
|
|
zvmem2.c)
|
|
- A restore in a different invocation of gs_run_string than the
|
|
corresponding save would stop reading the string. (files.h, gsmain.c,
|
|
iccinit.c, zfile.c)
|
|
- The Type 1 rasterizer state included a pointer into the middle of
|
|
an object, confusing the garbage collector. (zchar1.c, zfont1.c)
|
|
- When the garbage collector deleted a name, it didn't zero out the
|
|
string pointer. (iname.c)
|
|
- On platforms where obj_align_mod > 4, the memory manager could
|
|
access 1 beyond the end of its freelists. (iastate.h)
|
|
- makefont and scalefont didn't check the type of their font operand
|
|
soon enough. (zfont.c)
|
|
- restore didn't finalize the objects it freed. (isave.c)
|
|
- restore didn't free system VM. (isave.c)
|
|
- Freeing a ref array that occupied an entire chunk didn't free the
|
|
chunk. (ialloc.c)
|
|
|
|
Adds a .runexec operator which implements the 'close if error' function of
|
|
run. (zfile.c, zfileio.c)
|
|
|
|
Moves the obsolete writeppmfile operator into a separate file. (zfileio.c,
|
|
zwppm.c)
|
|
|
|
Makes the statistics returned by the memory manager more accurate.
|
|
(ialloc.c, zvmem.c)
|
|
|
|
Adds a (read-only) %Calendar% IODevice. (zdevcal.c)
|
|
|
|
Adds a "hook" in the character operators to allow external code to
|
|
intervene; this is needed for a customer. (ichar.h, zchar.c, zchar2.c)
|
|
|
|
Makes control-D (0x04) a self-delimiting token, like left bracket. THIS IS
|
|
A NON-BACKWARD-COMPATIBLE CHANGE, but it should not have any adverse
|
|
effects. (scanchar.h, iscan.c, iscantab.c)
|
|
|
|
Changes the error stack printout so that it puts line breaks between items
|
|
iff the items are being printed with ==. (gs_init.ps)
|
|
|
|
Uses finalization to close streams being freed. (igc.c, zfile.c, ziodev.c)

Fixes bugs:
|

- Embedded Type 1 fonts that invoked save and restore while being
|
|
read caused an error. (pdf_font.ps)
|
|
- Large files that referenced a non-alphabetic font for the first
|
|
time late in the file could cause an error. (pdf_main.ps)
|
|
|
|
</pre><h3><a name="V3.29_Streams"></a>Streams</h3><pre>
|

|
|
Fixes bugs:
|
|
- SubFileDecode streams didn't copy partial matches of the EOD
|
|
string into their output. (sfilter1.c)
|
|
|
|
Makes switching between read and write modes a stream procedure. (stream.h,
|
|
sfile.c, sfileno.c, stream.c, zfileio.c)
|
|
|
|
Makes file streams close themselves when finalized. (We can't do this for
|
|
other streams, because finalization procedures aren't allowed to free
|
|
storage explicitly.) (stream.h, sfile.c, sfileno.c, stream.c)
|
|
|
|
</pre><h3><a name="V3.29_Library"></a>Library</h3><pre>
|
|
|
|
Fixes bugs:
|
|
- The obsolete files gcdefs.h and gsfile.c were still included in
|
|
the fileset.
|
|
- A number of places didn't deal with null patterns properly (p_tile
|
|
== 0). (gxdcolor.h, gspcolor.c, gxpcmap.c)
|
|
- The pattern tiling algorithm was numerically unstable, especially
|
|
if the X/YStep vectors were close to the axes. (gxcolor2.h, gspcolor.c,
|
|
gxpcmap.c)
|
|
- setdeviceparams checked the values of read-only byte array
|
|
parameters incorrectly. (gsdparam.c)
|
|
- The statistics macros in gxfill.c didn't use DO_NOTHING when
|
|
disabled. (gxfill.c)
|
|
- Changing the orientation of a device closed and reopened the
|
|
device unnecessarily. (gsdparam.c)
|
|
- ioerrors occurring when writing command lists weren't reported
|
|
properly. (gxclist.h, gxclist.c)
|
|
- Errors from device procedures weren't always propagated up to
|
|
clients. (gsimage1.c, gsimage3.c, gxclip2.c, gxclist.c)
|
|
- Overflowing the fixed-point translation values in the CTM caused a
|
|
floating point exception rather than a limitcheck. (gxmatrix.h, gscoord.c)
|
|
- charpath set the current point correctly, but didn't append a
|
|
moveto element to the path. (This mostly affected Mathematica output.)
|
|
(gzpath.h)
|
|
- Image devices mapped colors incorrectly. (gdevmem.c, gdevm16.c)
|
|
- On devices with color capability but fewer than 4 bits per pixel,
|
|
color halftones didn't work (and could cause an arithmetic exception).
|
|
(gxdither.c)
|
|
- Black-on-white memory devices didn't map colors properly.
|
|
(gdevprn.h, gxdevice.h, gxdevmem.h, gdevmem.c, gdevm1.c, gsdevice.c)
|
|
- Memory devices with a non-zero origin in their initial matrix
|
|
clipped the image improperly. (gsdevice.c)
|
|
- The Type 1 rasterizer state included a pointer into the middle of
|
|
an object, confusing the garbage collector. (gstype1.h, gxfont1.h,
|
|
gxtype1.h, gstype1.c, gxhint2.c)
|
|
- The band rasterizer could produce garbled output for images
|
|
(including characters) on 64-bit architectures. (gxclread.c)
|
|
- Bounding boxes (for pathbbox and setbbox) could be slightly
|
|
inaccurate. (gsmatrix.c)
|
|
- On 64-bit architectures, halftone tiles less than 16 bits wide
|
|
were handled incorrectly. (gxclist.c)
|
|
|
|
Adds an .IsPageDevice boolean device parameter (normally read-only).
|
|
(gsdparam.c)
|
|
|
|
Removes the library code for implementing the obsolete writeppmfile
|
|
operator. (gswppm.c)
|
|
|
|
Makes the default matrix (for initmatrix and defaultmatrix) a settable
|
|
parameter in the graphics state. (gscoord.h, gzstate.h, gscoord.c,

gsdevice.c, gsdparam.c)
|
|
|
|
Makes the statistics returned by the memory manager more accurate.
|
|
(gsmemory.h)

|
|
|
Adds a compile-time flag to choose whether or not to force Type 1 hints to
|
|
"big pixel" boundaries when oversampling. (gstype1.c)
|
|
|
|
Changes the .PageCount device parameter back to PageCount, because the
|
|
change broke some scripts. (gsdparam.c)
|
|
|
|
Adds optimization for 90 degree rotated images with pure colors.
|
|
(gximage.h, gsimage.c, gsimage1.c)
|
|
|
|
Changes the band rasterizer so that replicated halftone tiles are written on
|
|
the band list in unreplicated form. (gsbitops.h, gxcldev.h, gsbitops.c,
|
|
gxclist.c, gxclread.c, gxht.c)

Fixes bugs:
|

- Some necessary casts of string parameters to (const byte *) were
|

omitted. (gp_mswin.c, gp_os2.c)
|
|
|
|
Adds the psmono and bit* drivers, and removes the p*m drivers, in the OS/2,
|

32-bit MS-DOS, and 32-bit Windows configurations. (bcwin32.mak, os2.mak,

Fixes bugs:
|
|
- The Fontmap for Ultrix had somehow become slightly incorrect.
|
|
(Fontmap.Ult)
|
|
|
|
Removes the font file names from the dependency lists in cfonts.mak. This
|
|
makes cfonts.mak readily usable with any set of fonts, but it also means
|
|
that it will always run font2c, rather than being able to avoid this if the

.c file is up to date. (cfonts.mak)

</pre><h3><a name="V3.27_Interpreter"></a>Interpreter</h3><pre>

|
|
Fixes bugs:
|
|
- Some operators could fail if the stdxxx streams weren't currently
|
|
open. (files.h, zfileio.c, ziodev.c)
|
|
- setpagedevice didn't handle unrecognized keys properly.
|
|
(gs_setpd.ps)
|
|
- The value returned for the HWColorMap device parameter was
|
|
allocated incorrectly, confusing the garbage collector. (iparam.c)
|
|
- Typing ahead at the >>showpage<< prompt no longer caused all
|
|
further pages to be processed without stopping. (gs_init.ps)
|
|
- Setting DEVICEWIDTHPOINTS or DEVICEHEIGHTPOINTS on the command
|
|
line caused a typecheck. (gs_init.ps)
|
|
- The garbage collector didn't handle halftone threshold arrays
|
|
properly. (zht2.c)
|
|
- setdefaulttimeouts caused an error on Level 2 systems.
|
|
(gs_lev2.ps)
|
|
- cvi and cvr weren't equivalent to token followed by a type check.
|
|
(iscan.h, iscannum.h, iscan.c, iscannum.c, ztoken.c, ztype.c)
|
|
- In Level 2 systems, image and colorimage didn't allow 12 bits per
|
|
sample. (zpaint.c)
|
|
- If debugging was enabled, the garbage collector printed spurious
|
|
error messages about the allocator objects not being in a chunk. (ialloc.c)
|
|
- restore didn't reset the count of operator procedures, so the
|
|
operator procedure table could fill up. Fixing this required splitting the
|
|
op_array_table into a global table and a local table. (opdef.h, iinit.c,
|
|
iutil.c, zmisc.c)
|
|
- .forgetsave could leave a dangling pointer in the memory manager,
|
|
causing an access error. (ialloc.c, isave.c)
|
|
- Freed objects weren't always marked as freed, which could confuse
|
|
the memory validator. (ialloc.c)
|
|
- .forgetsave didn't mark inner chunk headers as free, leading to
|
|
access errors. (isave.c)
|
|
|
|
Changes the representation of operator procedures so that they point
|
|
directly to their definition in the op_array_table. (iref.h, opdef.h,
|
|
idebug.c, igc.c, igcref.c, interp.c, zmisc.c)
|
|
|
|
Removes .makeglobaloperator. (zmisc.c)
|
|
|
|
Adds patches to discard some common garbage produced by H-P-oriented
|
|
applications and drivers. (gs_init.ps)
|
|
|
|
Changes the >>showpage<< prompt so that if the input reaches EOF, the
|
|
interpreter still stops after the next >>showpage<<, rather than processing
|
|
all subsequent pages. This is a consequence of the bug fix that
|
|
automatically reopens the stdxxx files.
|
|
|
|
Adds an optional dictionary parameter for the RunLengthEncode/Decode
|
|
filters, to allow specifying EndOfData. The default is true. (zfilter.c)
|
|
|
|
Adds ByteTranslateEncode/Decode filters. (zfilter2.c)
|
|
|
|
</pre><h3><a name="V3.27_Streams"></a>Streams</h3><pre>

Fixes bugs:
|
|
- The K > 0 option of the CCITTFaxDecode filter switched back to 2-D
|
|
encoding if an output buffer boundary fell in the middle of a 1-D line, and
|
|
signalled an error if an input buffer boundary fell in the middle of an EOL.
|
|
(scfd.c)
|
|
|
|
Adds an EndOfData flag to the RunLengthEncode/Decode filters. If true, RLE
|
|
generates 128 as EOD, and RLD recognizes it; if false, RLE does not mark
|
|
EOD, and RLD ignores 128. (srlx.h, gxclist.c, gxclread.c, sfilter1.c)

produce sufficiently correct output (since the interface only provides integer
|
|
coordinates). (gdevx.c, gdevwddb.c)
|
|
|
|
In response to patent-related actions by Unisys and CompuServe, removes the
|
|
GIF driver. (*.mak)
|
|
|
|
Changes dci_std_color (and std_device_std_color_* and prn_device_std_*) so
|
|
that if the number of bits per pixel is 32, the device is defined as CMYK
|
|
rather than RGB. (gxdevice.h)
|
|
|
|
Removes the tseng8 device, which is no longer useful. (devs.mak, gdevsvga.c)

(gxstroke.c)
|
|
- Attempting to draw an arc with zero radius could cause a numeric

exception. (gspath1.c)
|
|
- Setting the Orientation of a device to null resulted in actually
|
|
setting it to a random value. (gsdparam.c)

Changes the link list generator so it eliminates duplicate library requests.
|

(gsmain.c)
|
|
- The interpreter could (incorrectly) attempt to expand the e-stack.
|
|
(istack.h, interp.c, istack.c)
|
|
- zfproc.c called memcpy but didn't include memory_.h. (zfproc.c)
|
|
- A garbage collection occurring within a 'save' would often smash
|
|
memory. (igc.c)
|
|
- If the last character returned by the procedure of a procedure-based
|
|
filter was \r, readline could get an endless loop. (zfileio.c)
|
|
- Saving a change to a ref member of a structure confused the garbage
|
|
collector. (isave.h, isave.c, zdict.c)
|
|
- The -Zu debugging printout could cause an access error under rare
|
|
circumstances. (isave.c)
|
|
- Save objects could get allocated in global VM, causing dangling
|
|
references. (zvmem.c)
|
|
- The vmsave object created by the interpreter for a save didn't get
|
|
freed properly if the memory manager created an invisible save level, which
|
|
could cause the next garbage collection to crash. (zvmem.c)
|
|
- 'run' always printed an error message, rather than letting the
|
|
top-level control loop do it. (gs.c, gs_init.ps)
|
|
|
|
Adds support for duplex devices. (gxdevice.h, gsdparam.c, gs_statd.ps,

|
</pre><h3><a name="V3.24_Interpreter_PostScript"></a>Interpreter (PostScript)</h3><pre>

- The .local/global allocation operators always allocated in system
|
|
VM. (zsysvm.c)
|
|
- setpage[params] caused an error. (gs_lev2.ps)
|
|
- If an error occurred during a cshow or (x|y|xy)show, the interpreter
|
|
freed the enumerator twice. (zchar.c, zchar2.c)
|
|
|
|
Changes setpageparams so that orientation = 0 means portrait. This is not
|
|
compatible with AGFA's convention for roll-feed devices, but it is compatible
|
|
with the more common cut-sheet printers. (gs_statd.ps)
|
|
|
|
Adds meaningful values for the Emulator resource. (gsmain.c, gs_res.ps)
|
|
|
|
Makes -Z? validate the state of memory before and after save and restore.

|
- PDF to PostScript conversion didn't work at all. (It still doesn't
|
|
work very well.) (pdf_2ps.ps, pdf_main.ps)
|
|
- Images with an Indexed color space and no Decode entry caused an
|
|
error. (pdf_draw.ps)
|
|
- The 'Page <n>' messages were printed even if QUIET was set.
|
|
(pdf_main.ps)
|
|
|
|
Changes the interpreter so that when it encounters an unknown operator, it
|
|
prints an error message and continues, rather than signalling an error.
|
|
(pdf_base.ps)
|
|
|
|
Makes F a synonym for f if there is nothing on the operand stack, to
|
|
compensate for a bug in some Adobe software. (pdf_base.ps)
|
|
|
|
Changes pdfgetpage so it uses 1-origin rather than 0-origin indexing. THIS IS
|
|
A NON-BACKWARD-COMPATIBLE CHANGE. (pdf_main.ps)

caused an invalid memory access. (gspcolor.c)
|
|
- If a color image required clipping, black or white pixels might

be rendered with incorrect (random) colors. (gxcpath.c)
|
|
- Reference counts for color spaces were sometimes set too high, so

|
- The character cache could get confused if the Encoding for the

|
character wasn't a name. (gschar.c)

Fixes bugs:
|
|
- An off-by-1 test in the roll operator caused it to smash the
|
|
stack if the operand stack had overflowed into additional blocks.
|
|
(zstack.c)
|
|
- The default CIE color rendering dictionary didn't assume a
|
|
reasonable intermediate (XYZ) space. (gs_lev2.ps)
|
|
- CIE color mapping tables weren't traced properly by the garbage
|
|
collector. (gscie.h, gscie.c, zcie.c)
|
|
- If the very last character of a file was a ^M, the scanner
|
|
(incorrectly) signaled a syntaxerror. (iscan.c)
|
|
- If an operator could return both a typecheck and a
|
|
stackunderflow, it always returned a stackunderflow, which doesn't match
|
|
the behavior of Adobe interpreters. (opcheck.h, idparam.c, interp.c,
|
|
iutil.c, z*.c)
|
|
- astore, dictstack, and execstack could return a spurious
|
|
invalidaccess error (or fail to detect an invalid access) if the operand
|
|
stack had overflowed into additional blocks. (istack.c)
|
|
- The garbage collector didn't relocate pointers to names! (Bug
|
|
introduced in 3.20.) (iname.h)
|
|
- If the dictionary stack overflowed into additional blocks, the
|
|
cached value pointer for a name could get set incorrectly, and also not get
|
|
relocated by the garbage collector. (idict.c)
|
|
- If the dictionary stack overflowed into additional blocks, the
|
|
post-GC fixup of cached value pointers in names could cause an addressing
|
|
error. (igc.c)
|
|
- With the -Z? switch set, the garbage collector could incorrectly
|
|
report that objects or strings weren't in any chunk. (igc.c)
|
|
- << /a 1 /a 2 >> /a get gave the value 2 rather than 1.
|
|
(gs_init.ps)
|
|
- Numbers in binary object sequences and encoded number arrays
|
|
didn't work properly on machines where sizeof(short) != 2 or sizeof(long)
|
|
!= 4. (ibnum.c)
|
|
- The put operator for dictionaries allowed null as a key.
|
|
(idict.h, idict.c)
|
|
- >> didn't give an error if there were an odd number of values on
|
|
the stack above the next mark. (gs_init.ps)
|
|
- Operations that explicitly freed ref objects (setting a CIE
|
|
colorspace, resizing a dictionary, popping a block off a stack) could
|
|
corrupt storage. (ialloc.c)
|
|
- The -Z@ switch, which fills freed blocks with a recognizable bit
|
|
pattern, could incorrectly overwrite freed blocks in previous save levels,
|
|
causing invalid memory accesses. (ialloc.c)
|
|
- Since streams freed by a restore weren't marked as free, they
|
|
could confuse the garbage collector and lead to invalid memory accesses.
|
|
(zfile.c)
|
|
- If one of the built-in dictionaries overflowed during
|
|
initialization, no error was reported -- entries were simply discarded.
|
|
(iinit.c)
|
|
- If the level2.dev feature was combined with certain other
|
|
features, the current languagelevel was 2 when some gs_*.ps files were
|
|
loaded, causing them to load incorrectly. (gs_btokn.ps, gs_setpd.ps)
|
|
- If readline read a line that ended with only a CR (no LF)
|
|
followed by an end-of-file, it incorrectly closed the stream. (zfileio.c)
|
|
|
|
Adds a .cond operator, similar to the Lisp multi-arm conditional.
|
|
(zcontrol.c)
|
|
|
|
Adds a .makeglobaloperator operator, allowing the definition of operator
|
|
procedures in local VM that turn into global operators, provided the save
|
|
level is zero. (iref.h, opdef.h, iinit.c, interp.c, zmisc.c)
|
|
|
|
Note: the fix for returning typecheck vs. stackunderflow requires that all
|
|
operators (or other code) that uses return_error(e_typecheck) to indicate
|
|
an incorrect object type on the operand stack must change this to
|
|
return_op_typecheck(op), where op points to the operand. THIS IS A

|
|
(store.h)
|
|
- currentcacheparams only returned 2 values instead of 3.
|
|
(zfont.c)
|
|
- ustroke popped one element too many off the stack if a matrix was
|
|
supplied. (zupath.c)
|
|
- inu[eo]fill popped one element too many off the stack.
|
|
(zupath.c)
|
|
- The color rendering dictionary was initialized to null rather
|
|
than a valid dictionary. (gs_lev2.ps)
|
|
- An invalid IODevice resource named "9" got created. (gs_res.ps)
|
|
- bytesavailable often caused an error rather than returning -1.
|
|
(zfileio.c, stream.c)
|
|
- The insideness testing operators always returned true if the
|
|
aperture was defined by a user path rather than a point. (zupath.c)
|
|
- If INITIAL_DICTIONARIES was defined in the makefile, the
|
|
definition of the initial_dictionaries array was missing a comma.
|
|
(iinit.c)
|
|
- Even if userdict appeared in INITIAL_DICTIONARIES, gs_init.ps set
|
|
its maxlength to 200. (gs_init.ps)
|
|
- Setting a CIE color space left a garbage value on the stack.
|
|
(zcie.c)
|
|
- If a file or filter was opened and then closed, opening a file
|
|
subsequently within a 'save' could lead to a memory access error in the
|
|
garbage collector. (zfile.c)
|
|
- Setting an Indexed or Separation color space could cause a crash
|
|
either in the garbage collector or when printing out the e-stack.
|
|
(icsmap.h, zcsindex.c, zcssepr.c)
|
|
- Invoking a filter with an invalid data source or sink could cause
|
|
a memory access error (bug introduced in 3.20). (zfilter.c)
|
|
- Invoking stringwidth on a font whose BuildChar procedure did a
|
|
save could cause a memory manager error or infinite loop, because
|
|
stringwidth attempted to use an inapplicable shortcut. (gschar.c)
|
|
- The bounding box for rendering stroked Type 1 characters didn't
|
|
take square caps and miter joins into account. (gs_type1.ps)
|
|
- Invoking filter with DCTDecode or DCTEncode could cause an
|
|
addressing error if no dictionary argument was supplied. (zfdctd.c,
|
|
zfdcte.c)
|
|
- The Generic resource, the Font resource, and half a dozen
|
|
resources with no predefined instances all shared the same Instances
|
|
dictionary. (gs_res.ps)
|
|
- The temporary null device allocated for stringwidth was never
|
|
freed. (gschar.h, gschar.c, zchar.c)
|
|
- Internal operators, and structures that might be freed on stack
|
|
unwinding, could "escape" from the e-stack. (zcontrol.c, ztype.c)
|
|
- makefont and scalefont didn't properly handle a font whose
|
|
Encoding had been changed. (bfont.h, zfont.c, zfont2.c)
|
|
- Type 1 fonts with PaintType = 2 incorrectly checked for an xfont.
|
|
(gxfont.h, gschar.c, gsfont.c, zchar1.c, zfont1.c, zfont2.c)
|
|
- Specifying a string argument with -d...=(...) or -d...=<...>
|
|
would cause an invalidaccess error. (gs.c)
|
|
- The environment for encapsulated jobs didn't rebind quit to stop
|
|
in userdict. (gs_lev2.ps)
|
|
- restore didn't deal properly with open files on the e-stack.
|
|
(zvmem.c)
|
|
- Even with the '-' switch, Ghostscript would try to read ahead in
|
|
the input stream rather than processing input character-by-character.
|
|
(ziodev.c)
|
|
- If an error occurred with a unreadable dictionary on any stack,
|
|
the standard error printer would get into an error loop and exit the
|
|
interpreter. (gs_init.ps)
|
|
- The for_roots macro in igc.c used ap rather than mem as its
|
|
second formal parameter. (This typo had no effect on the executable
|
|
program.) (igc.c)
|
|
- If saving the stacks for an error caused a GC request, a value
|
|
could get stored into an improper variable on the C stack, causing havoc.
|
|
(interp.c)
|
|
- setdash checked to make sure that the distance array had read
|
|
access; Adobe interpreters don't check this. (zgstate.c)
|
|
- The roots for gs_run_string and gs_interpret weren't registered
|
|
properly, which could cause a dangling reference in the case of a restore
|
|
whose save had been done earlier. (gsmain.c, interp.c)
|
|
|
|
Adds an OpenOutputFile Boolean device parameter for printer devices; if
|
|
true, the device opens the OutputFile at the time the device is opened,
|
|
instead of waiting for the first showpage. This helps with synchronization
|
|
when the OutputFile is a pipe. (gdevprn.h, gdevprn.c)
|
|
|
|
Changes the BEGIN/END_OP_DEFS macros to require an explicit { and } at each
|
|
use. (gsmain.c, interp.c, z*.c)
|
|
|
|
Arranges things so that the operators that the interpreter handles
|
|
specially are assigned the first N operator indices [internal change only].
|
|
(interp.h, iinit.c, interp.c)
|
|
|
|
Changes the operators max and min to .max and .min, to avoid conflicts with
|
|
PostScript programs that use these names for variables and also use 'bind'.
|
|
THIS IS A NON-BACKWARD-COMPATIBLE CHANGE from programs that depend on
|
|
'bind' binding in these operators; however, we have also defined procedures
|
|
max and min that just call the operators, which should take care of any
|
|
ordinary code. (*.ps, zrelbit.c)

|
dictionaries with 8K or more elements. (igcref.c)
|

- >> could leave the stacks in a questionable state if it failed.
|
|
(gs_init.ps)

|
(gsdevice.c)
|
|
- The PageSize computation in gx_default_put_params could overflow
|
|
on 16-bit machines. (gsdparam.c)

|
- An omitted 'static' on an initialized array caused a compiler
|
|

|
actually carried out, gs_image_cleanup could attempt to free a random

- For CMYK devices, the transfer functions were being applied to
|
|
the CMYK values rather than the complemented RGBW values. (gxcmap.c)

|
than those of the target; this could cause incorrect colors for patterns on

|
rectangle, it could fail to clip properly thereafter. (gxacpath.c)

- The standard transfer function considered gray values above
|

roughly 0.994 equivalent to white; 0.999 is a better value. (gs_init.ps)
|
|
- The transfer, black generation, and undercolor removal functions
|

- JPEGSRC was defined in gs.mak rather than in jpeg.mak. (gs.mak,

Changes the version numbering scheme back to A.BC, since people seem to be

<h2><a name="Version3.02"></a>Version 3.02 (8/30/94)</h2>
|
|
|
|
<p>
|
|
This is another bug fix release. It was distributed only to a few people,
|
|
since the new X Windows color mapping code is not reliable yet.
|
|
|
|
<h3><a name="V3.02_Documentation"></a>Documentation</h3><pre>
|
|
|
|
Fixes bugs:
|
|
- make.doc, but not unixtail.mak, called for setting PLATFORM=unix_
|
|
on SVR4 platforms. (unixtail.mak)
|
|
- drivers.doc contained some wording that suggested that
|
|
Ghostscript always used RGB colors internally. (drivers.doc)
|
|
- The definition of gx_device in drivers.doc had gotten out of sync
|
|
with gxdevice.h. (drivers.doc)
|
|
- README claimed that Ghostscript is not compatible with the
|
|
VAX/VMS DEC C compiler, which is no longer true. (readme)
|
|
|
|
Adds a new section on printer drivers to drivers.doc. (drivers.doc)
|
|
|
|
Adds a large number of new display boards to the 800x600 SVGA section of
|
|
use.doc. (use.doc)
|
|
|
|
Adds a bug report form to the README file. (readme)
|
|
|
|
Notes that OSF/1 AXP systems require changing the definition of INSTALL
|
|
from install to installbsd. (make.doc)
|
|
|
|
</pre><h3><a name="V3.02_Procedures"></a>Procedures</h3><pre>
|
|
|
|
Removes -Wno-uninitialized from the gcc flags, and fixes all the places (in
|
|
Aladdin's code only) that need to be fixed to pacify gcc after doing this.
|
|
(gcc-head.mak, gdevgif.c, gdevmem2.c, gdevpcl.c, gs.c, gsht1.c, gsimpath.c,
|
|
gsutil.c, gxclread.c, gxpcopy.c, gxstroke.c, idict.c, iscannum.c, stream.c,
|
|
zdevice2.c) (NOT FINISHED YET)
|
|
|
|
Adds a FAKEFONTS switch that makes fake entries in FontDirectory for
|
|
unloaded fonts, for the benefit of programs that think they can find all
|
|
the available fonts by scanning FontDirectory. (gs_fonts.ps, gs_init.ps)
|
|
|
|
</pre><h3><a name="V3.02_Utilities"></a>Utilities</h3><pre>
|
|
|
|
Fixes bugs:
|
|
- ps2epsi didn't work, because setdevice now erases the page.
|
|
(ps2epsi.ps)
|
|
- ps2epsi didn't work, because -dNODISPLAY installs a null device
|
|
with 0 width and height. The fix -- to remove the -dNODISPLAY -- is not
|
|
satisfactory, because it opens an unnecessary window. (ps2epsi)
|
|
|
|
</pre><h3><a name="V3.02_Drivers"></a>Drivers</h3><pre>
|
|
|
|
Fixes bugs:
|
|
- gdev_fax_open was incorrectly declared static in gdevtfax.c,
|
|
causing the extern reference in the dfax drivers not to be resolved.
|
|
(gdevtfax.c)
|
|
- devs.mak included a duplicate definition of gdevmswn_h.
|
|
(devs.mak)
|
|
- The fax drivers didn't link properly in Level 1 systems, because
|
|
shc.c was omitted from their dependency list. (gs.mak, devs.mak)
|
|
- The TIFF/F drivers didn't set RowsPerStrip properly.
|
|
(gdevtfax.c)
|
|
- The TIFF/F drivers didn't byte-align the EOL properly. (scfx.h,
|
|
gdevdfax.c, gdevtfax.c, scfe.c, zfilter2.c)
|
|
- The rule for compiling gdevpccm.c incorrectly specified
|
|
dependency on gs.h rather than gx.h. (devs.mak)
|
|
- The rule for compiling gdevtfax.c didn't include time_.h as a
|
|
dependency. (devs.mak)
|
|
- The mode 2 compression routine for the DeskJet/LaserJet printers
|
|
was broken. (gdevpcl.c)
|
|
|
|
Removes the -O0 from the compilation rule for gdevsco.c, since it was
|
|
misplaced to begin with. (devs.mak)
|
|
|
|
Adds a maxDynamicColors X resource to control dynamic allocation in the
|
|
color map. Replaces the X color lookup algorithms with completely new
|
|
ones, for a substantial performance gain. (gdevx.h, gdevx.c, gdevxini.c)
|
|
|
|
Adds PageNumber, Software, and DateTime entries to the TIFF/F drivers.
|
|
(gdevtifs.h, gdevtfax.c)
|
|
|
|
Changes the margins for the LaserJet 4 to 0. (gdevdjet.c)
|
|
|
|
Adds a user-contributed LaserJet 4 driver that does Floyd-Steinberg
|
|
dithering. (gdevcdj.c)
|
|
|
|
</pre><h3><a name="V3.02_Platforms"></a>Platforms</h3><pre>
|
|
|
|
Fixes bugs:
|
|
- The exit codes for Ghostscript should be different on VMS.
|
|
(iastate.h, gs.c, gsmain.c, igc.c, igcref.c)
|
|
- The VMS DEC C compiler declares malloc and free in stdlib.h, and
|
|
delete and unlink in stdlib.h. (malloc_.h, stdio_.h)
|
|
- st_prn_device wasn't defined, which upset the VMS linker even
|
|
though there were no references. (gdevprn.h)
|
|
- stdpre.h didn't bring in the right headers when running gcc on
|
|
SCO Unix, causing compilation warnings/errors. (stdpre.h)
|
|
- The definition of rename in gp_sysv didn't include const for the
|
|
arguments. (gp_sysv.c)
|
|
- The definition of gettimeofday in gp_sysv didn't return any
|
|
value. (gp_sysv.c)
|
|
- time_.h didn't work on MS-DOS systems. (time_.h)
|
|
- math_.h didn't include <math.h> when compiling with gcc on VMS
|
|
systems. (math_.h)
|
|
- DesqView/X doesn't have a 'cat' command, which caused problems in
|
|
the linking step. (dvx-tail.mak)
|
|
|
|
Changes the definitions of popen in gdevpipe.c and gp_unix.c so they don't
|
|
specify the argument list. This is an attempt to get around the fact that
|
|
there is no easy way to detect whether the available header files declare
|
|
popen correctly (with const arguments), incorrectly (with non-const
|
|
arguments), or not at all. (gdevpipe.c, gp_unix.c)
|
|
|
|
Replaces VMS.MAK, VMS-CC.MAK, and VMS-AXP.MAK with new versions provided by
|
|
a user. (vms.mak, vms-cc.mak, vms-axp.mak)
|
|
|
|
Changes the 16-bit Borland makefiles so their standard configuration is
|
|
Level 1 plus color.dev (CMYK color and colorimage). (bc.mak, bcwin.mak)
|
|
|
|
</pre><h3><a name="V3.02_Fonts"></a>Fonts</h3><pre>
|
|
|
|
Fixes bugs:
|
|
- cfonts.mak still referred to some .gsf files that have been
|
|
replaced by .pfa files. (cfonts.mak)
|
|
- Compiled fonts got entered into FontDirectory, but didn't get
|
|
registered as resources. (gs_ccfnt.ps)
|
|
- The Cyrillic, Kana, Hershey .gsf, and URW fonts didn't include a
|
|
necessary systemdict begin/end, which caused them to fail in badly designed
|
|
environments. (fonts/f*.gsf, fonts/h*.gsf, fonts/?0*.gsf)
|
|
|
|
Changes the default target directory in cfonts.mak from fonts/c to .;
|
|
changes the names of the Zapf Chancery compiled font procedures from c* to
|
|
zc*. (cfonts.mak)
|
|
|
|
Adds more fonts from the Adobe Type Manager package for MS Windows to
|
|
Fontmap.ATM. (fontmap.atm)
|
|
|
|
Adds the entire set of 35 standard fonts to the ccfonts feature in gs.mak;
|
|
removes all the compilation rules for compiled fonts, since these rules are
|
|
in cfonts.mak already. (gs.mak)
|
|
|
|
</pre><h3><a name="V3.02_Interpreter"></a>Interpreter</h3><pre>
|
|
|
|
Fixes bugs:
|
|
- kshow executed a null, rather than the correct procedure, between
|
|
the characters of the string, and got a typecheck error at the end.
|
|
(zchar.c)
|
|
- MultiMaster fonts computed their side bearing and width
|
|
incorrectly, producing incorrect output. (zchar1.c)
|
|
- There was no structure definition for gs_type1_state, so a GC
|
|
during the execution of an OtherSubrs procedure could scramble pointers in
|
|
the saved state. (zchar1.c, zfont1.c; also affects library, see below)
|
|
- kshow didn't work properly if the kerning procedure changed the
|
|
depth of the operand or dictionary stack. (zchar.c)
|
|
- If the element count for roll was too large by only 1 or 2, the
|
|
result was a crash rather than a rangecheck. (zstack.c)
|
|
- restore didn't undo currentgstate. (igstate.h, store.h,
|
|
gsstate.c, zdevice2.c, zdps1.c, ztype.c)
|
|
- The scanner didn't set the local bit properly in a suspended
|
|
state. (iscan.c)
|
|
- copypage disregarded #copies. (gs_init.ps)
|
|
- An incorrectly declared pointer led to addressing faults on
|
|
16-bit systems. (zchar1.c)
|
|
- The cache for Separation colors was allocated with one element
|
|
too few. (zcsindex.c)
|
|
|
|
Changes `executive' so that if an error other than EOF occurs in the
|
|
reading of the statement, the interpreter prints the error message, but
|
|
control remains in the executive loop. (This isn't a very good fix; a
|
|
better one will require refactoring executive / execute / run.)
|
|
(gs_init.ps)
|
|
|
|
Changes dictionary undo saving to use the new ref_must_save macro [internal
|
|
change only]. (idict.c)
|
|
|
|
Moves configuration definitions from iinit.c to gconfig.c. (gcdefs.h,
|
|
interp.h, gconfig.c, gs.c, iinit.c, zmisc2.c, gs.mak)
|
|
|
|
Moves =string from systemdict to userdict for Adobe compatibility.
|
|
(gs_init.ps)
|
|
|
|
Starts to implement the Interpolate flag in image dictionaries. See under
|
|
Library below for restrictions. (zpaint.c, zimage2.c)
|
|
|
|
</pre><h3><a name="V3.02_Streams"></a>Streams</h3><pre>
|

Fixes bugs:
|

- stream_compact attempted to compact a read-only string being used
|
|
as the data source of a filter. (sbasic.c, stream.c)
|
|
|
|
Adds an EncodedEOLAlign flag to the CCITTFaxEncode stream, to allow direct
|
|
generation of TIFF/F output. (scfx.h, scfe.c, zfilter2.c)
|
|
|
|
</pre><h3><a name="V3.02_Library"></a>Library</h3><pre>
|
|
|
|
Fixes bugs:
|
|
- There was no structure definition for gs_type1_state, so a GC
|
|
during the execution of an OtherSubrs procedure could scramble pointers in
|
|
the saved state. (gxfont1.h, gxtype1.h, gstype1.c, gxhint2.c)
|
|
- A couple of calls had to discard const, but didn't include the
|
|
necessary cast. (gxpcmap.c)
|
|
- makeimagedevice refused to accept an empty image. (gsdevice.c)
|
|
- The extra parentheses around arguments in memory_.h caused some
|
|
compilers to fail. (memory_.h)
|
|
- Floating point overflows during coordinate conversion terminated
|
|
Ghostscript. (gxfarith.h, gxfixed.h, gsmatrix.c, gsmisc.c)
|
|
- Accents still weren't getting placed properly on characters
|
|
created with seac. (gstype1.c, gxhint2.c)
|
|
- The SGI C compiler couldn't handle the (perfectly legal)
|
|
definitions of dev_init_[open_]misc. (gxdevice.h)
|
|
- string_.h caused some problems with gcc on some versions of
|
|
Solaris. (string_.h)
|
|
- The halftone levels for color screens were computed incorrectly.
|
|
(gzht.h, gxdither.c)
|
|
- Color screens sometimes had vertical stripes of solid color
|
|
interspersed. (gxcht.c)
|
|
- Colors could get mapped incorrectly if a compiler aggressively
|
|
(and incorrectly) reordered the computation of procedure arguments
|
|
involving the unit_frac macro. (gxcmap.c)
|
|
- setcachedevice[2] insisted that the corners of the bounding box
|
|
be given in the correct order, i.e., llx < urx and lly < ury. (gschar.c)
|
|
- The image operator gave a limitcheck on unrotated 1-bit-per-pixel
|
|
images whose width in device coordinates exceeded 65529. (gsimage.c)
|
|
- The garbage collector didn't trace the input data of an
|
|
in-progress image operator correctly. (gsimage.c)
|
|
|
|
Changes the max_rgb and dither_rgb members of gx_device_color_info to
|
|
max_color and dither_colors, since Ghostscript now uses these for CMYK
|
|
devices as well. Also changes dither_gray to dither_grays. (gdevmem.h,

gdevprn.h, gxdevice.h, gdevbit.c, gdevcdj.c, gdevprn.c, gdevxini.c,

gsdparam.c, gxcht.c, gxcmap.c)
|
|
|
|
Starts to implement the Interpolate option for images. Currently this is
|
|
only implemented for image, not imagemask, and only for rotations that are
|
|
multiples of 90 degrees (possibly with reflection). (gsimage.h,
|

gsiscale.h, gximage.h, gsimage.c, gsimage1.c, gsiscale.c)

been withdrawn. (language.doc)
|
|
- drivers.doc didn't specify under what circumstances each
|

Fixes bugs:
|
|
- The CCITTFaxEncode filter could put out an EOB in the middle of
|
|
the data. (scfe.c)
|
|
|
|
Splits off the PixelDifferenceEncode/Decode filters into a separate
|
|
"feature". (gs.mak)

</pre><h3><a name="V3.01_Library"></a>Library</h3><pre>
|
|
|
|
Fixes bugs:
|
|
- gs_setcachedevice could return a garbage error code. (gschar.c)
|
|
- joins on stroked lines were incorrect if the device coordinate
|
|
system mapped +Y to +Y. (gxstroke.c)
|
|
- If gsmisc.c supplied versions of missing library routines, they
|
|
could clash with the names of the real ones if those were present
|
|
unexpectedly. (memory_.h, gsmisc.c)
|
|
- The initialization expression for is_open in the
|
|
dev_init_misc_open macro included a cast, which some compilers don't allow.
|
|
(gxdevice.h, gsdevice.c, gxclip2.c, gxpcmap.c)
|
|
- In Type 1 fonts, character that specified their side bearing and
|
|
width with sbw rather than hsbw gave an invalidfont error. (gstype1.c)
|
|
- Some procedures were declared inconsistently with regard to const
|
|
arguments. (gscie.c, gxpcmap.c, gxacpath.c, gxcmap.c)
|
|
- A few places still assumed that pointers occupied 4 bytes.
|
|
(gxclist.c)
|
|
- Rendering a gray halftone on a CMYK device called the device's
|
|
map_rgb_color procedure instead of map_cmyk_color. (gxdither.c)
|
|
|
|
Renames gsfile.c as gswppm.c. (gsfile.c, gswppm.c)
|
|
|
|
Implements the ability to cache arbitrarily transformed characters. This
|
|
is currently enabled by a compile-time flag in gschar.c. (gschar.c)

<h2><a name="Version3.0"></a>Version 3.0 (8/1/94)</h2>
|
|
|
|
<p>
|
|
This is the first full Level 2 version released to the public.
|
|
Unfortunately, we were not able to include setpagedevice in this release.
|

|
<h3><a name="V3.0_Documentation"></a>Documentation</h3><pre>
|
|
|
|
Fixes bugs:
|
|
- README didn't mention Aladdin's European distributor.
|
|
- psfiles.doc didn't describe some of the newer gs_*.ps files.
|
|
|
|
Notes that gcc -O2 (version 2.5.8 of gcc) generates incorrect code for some
|
|
modules on the H-P RISC architecture.
|
|
|
|
Notes that on AXP platforms running VMS, DEC C V4.0 is required.
|
|
|
|
</pre><h3><a name="V3.0_Procedures"></a>Procedures</h3><pre>
|
|
|
|
Fixes bugs:
|
|
- 'make clean' didn't delete devs.tr or t.tr.
|
|
- devs.mak was missing the entry for faxg32d.
|
|
- unixansi.mak omitted some drivers that were included in
|
|
unix-cc.mak and unix-gcc.mak.
|
|
|
|
Updates jpeg.mak to reference version 5beta1 of the IJG JPEG code.
|
|
|
|
Changes the version numbering scheme from A.B.C to A.B[CC]. I.e., the
|
|
first sub-release after 3.0 will be 3.01 or 3.001, not 3.0.1.
|
|
|
|
</pre><h3><a name="V3.0_Utilities"></a>Utilities</h3><pre>
|
|
|
|
Fixes bugs:
|
|
- ps2ascii didn't do a setglobal.
|
|
|
|
Adds an option to ansi2knr to convert ... to va_alist/va_dcl.
|
|
|
|
</pre><h3><a name="V3.0_Drivers"></a>Drivers</h3><pre>
|
|
|
|
Fixes bugs:
|
|
- The newly added faxg32d driver didn't have an entry in devs.mak.
|
|
- The BMP, GIF, and PCX drivers wrote out an incorrect color
|
|
palette (the blue values were too small).
|
|
- The vgalib driver had some compilation problems.
|
|
- The TIFF drivers didn't produce correct multi-page output.
|
|
|
|
Adds faxg32d and tiffg32d drivers.
|
|
|
|
Reinstates the DigiFax drivers, which were withdrawn when the new fax
|
|
drivers were added.
|
|
|
|
</pre><h3><a name="V3.0_Platforms"></a>Platforms</h3><pre>
|
|
|
|
Fixes bugs:
|
|
- gs_btokn.ps and gs_ccfnt.ps weren't installed on Unix platforms.
|
|
- The VMS module list omitted SBHC, included a non-existent GXDASH,
|
|
and had incorrect names for some of the IJG JPEG files.
|
|
- The VMS build scripts (vms*.mak) had incorrect "boilerplate".
|
|
- The VMS script file gssetmod.com had \r characters in it, as well
|
|
as \n characters.
|
|
- The echogs and genarch utilities didn't return the correct exit
|
|
codes under VMS.
|
|
- The VMS Fontmap had incorrect entries for the Courier and Charter
|
|
fonts.
|
|
- When running under Ghostview, Ghostscript didn't drain the input
|
|
pipe. (We fixed this with a temporary patch in gs.c; this isn't a good
|
|
solution for the longer term.)
|
|
|
|
</pre><h3><a name="V3.0_Fonts"></a>Fonts</h3><pre>
|
|
|
|
Fixes bugs:
|
|
- The free AvantGarde, Bookman, and Palatino font families had
|
|
incorrect FontBBox values.
|
|
- The 'f' and 'j' in the free AvantGarde-DemiOblique,
|
|
Bookman-DemiItalic, Bookman-LightItalic, and Palatino-Italic fonts were
|
|
chopped off on the right. (The bitmaps were chopped off in the original
|
|
BDF fonts from which these fonts were made.) ****** THIS PROBLEM WAS NOT
|
|
ACTUALLY FIXED. ******
|
|
|
|
</pre><h3><a name="V3.0_Interpreter"></a>Interpreter</h3><pre>
|
|
|
|
Fixes bugs:
|
|
- gs -h and gs -v didn't print the tertiary version number correctly.
|
|
- Binary object sequences with no strings or names didn't read in
|
|
correctly.
|
|
- Binary object sequences that crossed an input buffer boundary
|
|
didn't read in correctly.
|
|
- Binary object sequences read in as {[e1 .. en] e1 ... en} instead
|
|
of {[e1 ... en]}. (New bug in 2.9.x.)
|
|
- setpattern didn't set the current color space correctly if the
|
|
current color space wasn't a Pattern space.
|
|
- If the current color space was an uncolored Pattern space but the
|
|
current color was a colored Pattern, currentcolor returned extra values on
|
|
the operands stack.
|
|
- .buildfont1 in gs_type1.ps didn't force binding of the old
|
|
definition, causing ps2ascii to loop endlessly.
|
|
|
|
Adds a facility for writing and reading dictionaries in binary object
|
|
sequences. This is experimental and subject to change in the future.
|
|
|
|
</pre><h3><a name="V3.0_Streams"></a>Streams</h3><pre>
|
|
|
|
Fixes bugs:
|
|
- gs_run_string and ccinit didn't have any way to mark the string
|
|
as "foreign", which confused the GC.
|
|
|
|
</pre><h3><a name="V3.0_Library"></a>Library</h3><pre>
|
|
|
|
Fixes bugs:
|
|
- gxchar.h had an extra comma after the last element of the
|
|
show_width_status enum, which upset some compilers.
|
|
- stroke and strokepath didn't correctly skip zero-length segments
|
|
if the line width was less than one pixel, or if there was a closed subpath
|
|
consisting entirely of zero-length segments.
|
|
- strokepath sometimes incorrectly added a moveto at the end of the
|
|
path.
