heh. bug in pdfselect on compressed object streams. gc takes forever, no objects remain...
|
||
|
|
||
|
lazy nametree
|
||
|
lazy pagetree
|
||
|
|
||
|
builtin standard cmap files (?)
|
||
|
put unicode strings in text object, not font (a la metro)
|
||
|
|
||
|
xml parser
|
||
|
unicode normaliser
|
||
|
|
||
|
path stroke/dash/flatten work on real path struct
|
||
|
turn into gel as second step after stroke/flatten
|
||
|
add intersector for metro union/xor/difference stuff
|
||
|
|
||
|
image rescale to exact size instead of by integer quantas
|
||
|
|
||
|
public / private api
|
||
|
|
||
|
fix the shading code:
|
||
|
3 levels of detail patch mesh (quad, patch, tensor)
|
||
|
subdivide to triangles on the fly
|
||
|
draw tris as before
|
||
|
reuse more code in the parsing
|
||
|
error cleanup
|
||
|

--- WORLD ---
|
||
|
|
||
|
the fitz world is:
|
||
|
the set of resources:
|
||
|
trees, fonts, images, shades, colorspaces
|
||
|
the list of pages:
|
||
|
references to tree resources
|
||
|
opaque / transparent / invisible ?
|
||
|
|
||
|
input device drivers create a fitz world from a document
|
||
|
readps -- use ghostscript
|
||
|
readpdf -- use mupdf
|
||
|
readmetro -- use samus
|
||
|
|
||
|
the mapping from file -> pages and resources
|
||
|
internal to the driver, nothing fitz cares or knows about
|
||
|
should be lazy -- loaded on an as-needed basis
|
||
|
should be reference counted -- can free and reload resources
|
||
|
|
||
|
minimal api (that works for *all* input drivers)
|
||
|
open(file)
|
||
|
close()
|
||
|
nextpage()
|
||
|
|
||
|
extended api (that may or may not work optimally)
|
||
|
countpages()
|
||
|
loadpage(number)
|
||
|
|
||
|
output drivers take a fitz world and produce whatever
|
||
|
raster
|
||
|
writeps
|
||
|
writepdf
|
||
|
writemetro

--- OLD ---
|
||
|
|
||
|
immediate plan:
|
||
|
|
||
|
* clean up and 'freeze' public api
|
||
|
|
||
|
* get font bbox from fontdescriptor if available
|
||
|
* refactor image loading
|
||
|
* refactor xref loading/repair
|
||
|
* restructure build.c and interpret.c (ftb vs csi)
|
||
|
* fix the colorspace/pattern/shading material mess
|
||
|
* font loading:
|
||
|
- configuration... where to find system files (asian font archive?)
|
||
|
- system fontfile + cmap store
|
||
|
- embedded fontfile store
|
||
|
- split type3 and ftfont malloc (dont waste t3 charprocs on ft fonts)
|
||
|
- make ftfontfile separate struct w/ refcounting
|
||
|
- refactor font loading more. simple/cid/type3 have too much in common.
|
||
|
|
||
|
* structure low/high level stuff
|
||
|
- rewrite outline parser
|
||
|
- implement comments
|
||
|
|
||
|
* clean high-level api
|
||
|
|
||
|
- go through spec and check all features!
|
||
|
- altivec optimize
|
||
|
|
||
|
transparency (v2)
|
||
|
- everything!
|
||
|
|
||
|
colorspace conversions (v2)
|
||
|
- fast color cubes
|
||
|
- proper colorspace conversions
|
||
|
- gamut compression
|
||
|
- extended render intents
|
||
|
|
||
|
image rendering (v2)
|
||
|
- tiles
|
||
|
- dct case
|
||
|
- better filter than box
|
||
|
- lazy decoding
|
||
|
|
||
|
rendering
|
||
|
- fix glyphcache evictlast
|
||
|
- bbox culling per glyph
|
||
|
- render cache (link-nodes and scaled images and colorspaced shades)
|
||
|
|
||
|
fz_optimizetree()
|
||
|
- error & memory
|
||
|
- concatenate chained transforms
|
||
|
- remove identity transforms
|
||
|
|
||
|
for filters:
|
||
|
validate ahxd pushback
|
||
|
go through eof responsibility
|
||
|
be more defensive of api user errors
|
||
|
jbig2 rewrite
|
||
|
dctencode params
|
||
|
dctdecode app marker
|
||
|
jpxd rewrite (or do special trick to load into image directly)
|
||
|
