Inital commit of Native Quartz surface. The main missing functionality
is mask() support (which is just a noop right now, except for the simple
solid-alpha case).
src/check-def.sh checks that the list of symbols exported is the same as the
list of symbols in cairo.def, ie. symbols in public header files. (except for
symbols starting with _cairo)
src/check-plt.sh checks that no PLT entries exist for local function calls.
This makes sure we keep the 'slim' annotations uptodate.
These two are defined as tests in src/ and will be run during "make distcheck".
However, they are skipped if the commands 'nm' and 'readelf' are not found.
(We don't really rely on any functionality of eu-readelf, so using readelf
proper which should be more commonlly installed.)
This patch generates Type 1 fonts for the PS/PDF backends when TrueType
or Type 1 subsetting fails. This has the advantage over the current
Type 3 fallback of reduced font size and better quality rendering
in some PDF viewers. xpdf shows a large improvement in text display
quality with this patch.
Add a load_truetype_table function to cairo_scaled_font_backend_t and
use it to load the truetype sfnt tables. Implement this with freetype
for the freetype font backend and use GetFontData for win32. Atsui
remains unimplemented, and still falls back to type3 fonts.
Backends that use the font subsetting code should add the font subsetting
sources to the build. This is dont by setting libcairo_font_subset_sources,
in the conditional section for each backend. If any one is enabled, the
sources will be added to the build.
* src/Makefile.am:
Add cairo-lzw.c to sources
Remove erronous space at start of line
* src/cairo-lzw.c:
New file implementing _cairo_compress_lzw which does Lempel-Ziv & Welch
compression as used by postscript. Based on code from libtiff.
* src/cairo-output-stream.c:
Add _cairo_output_stream_write_base85_string which implements
an encoder for the ASCII85Decode postscript filter.
* src/cairoint.h:
Add _cairo_compress_lzw and _cairo_output_stream_write_base85_string.
* src/cairo-ps-surface.c:
Write Images LZW + Base85 encoded.
Change ps level to 2 (we only needed level 3 for FlateDecode).
Change DocumentData to Clean7Bit as we don't include binary data
anymore.
If the destination surface is a quartz surface, get the clip mask from it.
Added.
Keep a copy of the clip mask around.
(_cairo_surface_is_quartz): New function which determines if a given surface is a quartz surface.
Add test_paginated_surface_t which is another test surface enabled with --enable-test-surfaces. The test_meta_surface code served as the basis for cairo_paginated_surface_t so that test surface may be entirely superfluous now.
