3ae8c1ca65 Replace struct cairo_surface_backend with cairo_surface_backend_t 2005-01-13 14:48:15 +00:00
Carl Worth
a2af89b04a Replace all structure tags to have _ prefix. struct cairo_foo -> struct _cairo_foo Also, prefer cairo_foo_t over struct _cairo_foo in .c files. 2005-01-13 06:50:23 +00:00

5235dbb80f A NULL cairo_t * is not sane. 
Add freetype flags so that things work with freetype in a non-standard location, (a little extra work here since freetype doesn't use pkg-config).
Add several items culled from recent mailing list discussions.
Add bugs on cache locking and surface pattern scaling.

72832b9760 Scale factors shouldn't include mirroring. 
int32x32_64_mul and int64x64_128_mul are different from their unsigned compatriots

ad2225c6f4 Fix math library detection to use autotools helper 
Remove cache memory usage assertions as single objects can be larger than the cache size
Decompose font matrix transformations into a couple of helper routines. Return all metrics in font space.
Eliminate compiler warning
Expect glyph metrics to be in font space. Compute text extents by fetching one glyph metric at a time, transforming to user space and computing the overall bounding box.
use 'sincos' where available. Scale factors now ensure the non-scale transform is area preserving. Scale factors requires another parameter to mark the fixed axis.
Change license to LGPL Mark int32x32_64_mul as broken (which it still is)
Ensure each glyph is located as close to the specified position as possible
interface change to _cairo_matrix_compute_scale_factors

a850136805 Add -lz to CAIRO_LIBS when compiling the PDF backend.

e5d48545e0 Rename __internal_linkage to cairo_private and move it to the beginning of the line for function declarations. Also, drop unneeded "extern" from function declarations. 2004-12-21 13:22:44 +00:00

1a21b8289f With thanks to Kristian Høgsberg <krh@bitplanet.net>: 
Tag a few private functions/data that were missing __internal_linkage.
Mark cache backends as static.

eecfec86f1 Re-enabled __internal_linkage for all internal functions. Now avoid the warning by moving the * from the return type after the __internal_linkage macro. It looks awaful, but it keeps the compiler quiet. 2004-12-20 09:53:06 +00:00

5c1c5e67dc Add _cairo_gstate_restore_external_state, _cairo_fixed_integer_floor and _cairo_fixed_integer_ceil.

Implement floor and ceil
Restore surface clip region on restroe.
(_calculate_region_for_intermediate_clip_surface), (_cairo_gstate_clip_and_composite_trapezoids), (_cairo_gstate_show_surface), (_cairo_gstate_show_glyphs): Create intermediate clip surfaces of the minimal required size.

e3fe2138fe Split off from _cairo_xlib_surface_create to avoid roundtrip when size is already known. (cairo_xlib_surface_create): Simplified to just call XGetGeometry that defer to _cairo_xlib_surface_create_with_size. Add comment about remaining roundtrip and possible plans to eliminate it later with a new interface requiring width/height. 2004-12-20 08:52:47 +00:00

725d363877 Change return value from cairo_status_t to cairo_int_status_t to match definition in cairo_surface_backend_t. 2004-12-20 07:38:38 +00:00

5c143241df Note that text_cache_crash is expected to fail. 
Add test to demonstrate bug when item is too big for cache.
Really remove that refcount assertion this time.

7478ea5051 Add note that bug has been fixed. (main): Instrumentation code for testing cache destruction. 
Support tests that produce no output, (don't check image if (width,height) == (0,0)).
Add #include <assert.h> here rather than in multiple .c files.
Add const qualifier to static cache_arrangements table. (_cache_sane_state): Remove refcount assertion as it it false during the cairo_cache_destroy. (_cache_sane_state): #include <assert.h> moved up to cairoint.h (_entry_destroy): Fix bug in assertion (used_memory >= entry->memory), not >. (_cairo_cache_destroy): Fix timing of refcount decrement so that the destroy function actually works.

2b76ec2d46 Unconditionally destroy the old font, (otherwise, if the same font was selected twice in a row, a reference was lost to it, leading to assertion failures). 2004-11-13 19:46:18 +00:00

ed08ea6bba Change the signs of a variety of metrics, which were backwards. 
Return early if we found a rectangular clip at all, not just in error case.
Give render glyphset entry the negative bbox offsets it wants, not the bearings.

f8e632ab1e Add initial regression test suite. 
Don't AC_SUBST a dozen different FOO_CFLAGS and FOO_LIBS. Instead, incrementally build up just CAIRO_CFLAGS and CAIRO_LIBS.
Don't list flags that should get picked up via dependency information through Requires.
