Spotted with:
mutool draw -A0 -r600 -o out.ppm J11_acrobat.pdf

Short circuit any attempt to paint a pixmap with zero alpha.
|
|
|
|
In C we can't have a label as the only thing in a block.
|
|
|
|
Introduce FZ_PLOTTER defines to set which defines we required.
Add FZ_ENABLE define to set which document handlers are built
by default.
|
|
|
|
Use do {} while(--w) rather than while(w--) {} as this safes a
test each time around the loop.
|
|
|
|
Again, mainly so profiling works nicely.
|
|
Use this for plotters so we can see which ones are being used
in any given build.
Build with -DTRACK_USAGE to enable.
|
|
Only do int to int copying if we have an int to copy from.
Also, when copying int to int, copy int32_t to int32_t to make
us more future proof.

|
Try and help C avoid pointer aliasing issues. Some of this may not
help at all. None of it should hurt though.
|
|
fz_pixmaps now have an explicit stride value. By default no change
from before, but code all copes with extra gaps at the end of the
line.
The alpha data in fz_pixmaps is no longer compulsory.
mudraw: use rgb not rgba (ppmraw), cmyk not cmyka (pkmraw).
Update halftone code to not expect alpha plane.
Update PNG writing to cope with alpha less input.
Also hide repeated params within the png output context.
ARM code needs updating.

To avoid having to duplicate a fairly large block of code several
times, use repeated inclusion of a header with some macros to
generate optimised glyph plotters.
|
|
We have optimised plotters for 2 and 4 components (i.e. greyscale
and rgb). Add equivalent ones for CMYK.
|
|
Rather than generating fz_pixmaps for glyphs, we generate fz_glyphs.
fz_glyphs can either contain a pixmap, or an RLEd representation
(if it's a mask, and it's smaller).
Should take less memory in the cache, and should be faster to plot.
|
|
Broken in recent optimisations.
|
|
|
|
If we want the alternative versions we can pull them out of git
later.
