.SH DESCRIPTION
|
||
|
|
.I Ps2pdf
|
||
|
|
and
|
||
|
|
.I pdf2ps
|
||
|
|
convert from PostScript to PDF and back by invoking
|
||
|
|
.IR gs (1).
|
||
|
|
If
|
||
|
|
.I output-file
|
||
|
|
is not specified, they write to standard output.
|
||
|
|
If neither
|
||
|
|
.I input-file
|
||
|
|
nor
|
||
|
|
.I output-file
|
||
|
|
is not specified, they read from standard input and write to standard output.
|
||
|
|
.PP
|
||
|
|
The
|
||
|
|
.I gs-options
|
||
|
|
are passed to Ghostscript unaltered.
|
||
|
|
The most useful option to
|
||
|
|
.I ps2pdf
|
||
|
|
is
|
||
|
|
.BR -dCompatibilityLevel=\fIlevel ,
|
||
|
|
which sets the version of PDF to be written.
|
||
|
|
The default is
|
||
|
|
.BR 1.2 ;
|
||
|
|
.B 1.3
|
||
|
|
and
|
||
|
|
.B 1.4
|
||
|
|
are also possible.
|
||
|
|
Similarly, the most useful option to
|
||
|
|
.I pdf2ps
|
||
|
|
is
|
||
|
|
.BR -dLanguageLevel=\fIlevel ,
|
||
|
|
which sets the version of PostScript to be written.
|
||
|
|
The default is
|
||
|
|
.BR 2 ;
|
||
|
|
.B 1
|
||
|
|
and
|
||
|
|
.B 3
|
||
|
|
are also possible.
|
||
|
|
.PP
|
||
|
|
.I Ps2pdf
|
||
|
|
produces output competitive with
|
||
|
|
Adobe Distiller in most cases, and it
|
||
|
|
accepts all the embedded PDF-generation hints that Adobe Distiller does.
|
||
|
|
.PP
|
||
|
|
.I Pdf2ps
|
||
|
|
produces a PostScript file containing one large bitmap
|
||
|
|
per page. For a more direct and smaller translation,
|
||
|
|
use Adobe Acrobat's
|
||
|
|
.B -toPostScript
|
||
|
|
command-line option.

.IR Gs 's
|

|
|
.I pdfwrite
|
||
|
|
sometimes emits bad PDF at the default level 1.2.
|
||
|
|
Adding
|
||
|
|
.BR '-dCompatibilityLevel=1.4'
|
||
|
|
should cure it.
