Quick summary of changes:
- Move list of cairo source files out of src/Makefile.am and into
src/Sources.mk,
- Generate files src/Config.mk and src/Config.mk.win32 that choose
the right set of source files and headers based on configured
backends and features. This drastically simplifies building
using other build systems. The src/Makefile.win32 file needs
to be updated to reflect these changes.
- Add README files to various directories,
- Add toplevel HACKING file.

When the clip mask is empty we perform actions like composite 0x0
surfaces, which results in a lot of unnecessary work and allocations.
Avoid doing work when we know everything is clip out and take the
liberty of freeing any memory associated with the clop state.
|
|
Introduce an opaque cairo_reference_count_t and define operations on it
in terms of atomic ops. Update all users of reference counters to use
the new opaque type.
|
|
The wrapping of GCC attributes (such as cairo_private) needs to be
visible to any header file, including those that avoid cairoint.h such
as cairo-boilerplate. To achieve this we move the pre-processor magic to
its own header file and include it as required.
|
|
These were recently added, (as part of sparse integration?), but they
break boilerplate which reaches into at least cairo-types-private.h
and cairo-scaled-font-private.h. But boilerplate cannot see cairoint.h
or else it gets the internal sybol renaming, (with the INT_ prefix),
and then all the test suite tests refuse to link.
If this change reverts some recently-added functionality, (or
cleanliness), then we'll just need to find some other way to add that
back again without the breakage.
|
|
There are still some bits not quite working.
|
|
Insulate region-using code from implementation details;
at some point we'll want to switch to using 32-bit regions.
|
|
Mostly s/cairo_rectangle_int16_t/cairo_rectangle_int_t/,
as well as definitions to pick cairo_rectangle_int_t.
|
|
Yet another unconditionally successful function---so it's easier to return nothing.
|
|
Copying the clip region could fail, add error returns and propagate up
the call stack.
|

|

Previously, the convention was that static ones started with cairo_, but
renamed to start with _cairo_ when they were needed from other files and
became cairo_private instead of static...
This is error prune indeed, and two symbols were already violating. Now
all nil objects start with _cairo_.
|

|
|
Add new public API methods:
void cairo_clip_extents (cairo_t *cr, double *x1, double *y1,
double *x2, double *y2);
cairo_rectangle_list_t *cairo_copy_clip_rectangles (cairo_t *);
void cairo_rectangle_list_destroy (cairo_rectangle_list_t *);
Also add 'get-clip' and 'get-path-extents' tests.

This rectangle has regular integer values, not fixed-point values.
So the old name was horribly wrong and misleading, (and yes I think
it was even I that had suggested it).
|
|
This patch was produced with the following (GNU) sed script:
sed -i -r -e '/^[ \t]*\/?\*/ s/[ \t]+$//'
run on all *.[ch] files within cairo, (though I manually excluded
src/cairo-atsui-font.c which has a code line that appears as a comment
to this script).
|

|
|
This is in preparation for a later function addition for extracting
clip rectangles from a cairo_t, (which will add a public
cairo_rectangle_t).
|
|
We keep the clip in surface-backend coordinates always, so it needs
fixing whenever we change the target surface out in the gstate. The
only place this happens is in push_group, so fix it as part of
gstate_redirect().
|
|
add CAIRO_BEGIN_DECLS and CAIRO_END_DECLS, and move an enum from cairo-clip-private.h here (C++ doesn't like forward-declarations of enums). Final patch for allowing C++ backends.

hint and is not supported by all backends.
Store the antialiasing mode in the gstate and pass it to the backend for trapezoid rendering and for clipping.
Pass the antialiasing parameter down to the backend where appropriate.
Pass the antialiasing parameter down to the backend where appropriate.
Add support for A1 format trapezoid rendering, and remove the _create_mask_image function, creating a temporary image from memory we allocate and clear.
Support A1 masks to disable antialiasing using the RENDER extension when requested.
Support A1 masks to disable antialiasing using the RENDER extension when requested.
Blindly pass through the antialising parameter.
Add the antialiasing parameter but don't support it.
Add a test case and a reference image from the latest libpixman.
Add the new antialiasing disabling API to the docs.
Update progress on a parameter to disable antialiasing.

for 0 src/mask)
cairoint.h: Add a helper function to take clearing areas that are outside the source/mask but are cleared by unbounded operations.
src/cairo-xlib-surface.c (_cairo_xlib_surface_composite): Use _cairo_surface_composite_fixup_unbounded() as needed.
src/cairo-image-surface.c src/cairint.h: Keep track of whether the surface has a clip or not ... we need this for determining when we can bypass an intermediate mask for composite_trapezoids().
Create an intermediate mask of the right size with pixman_add_trapezoids() and composite that.
When rendering with an unbounded operator, create the intermediate mask ourselves and render with ADD to that, then composite the result.
Create an intermediate surface the size of the extents, render the glyphs to that then composite the results.
Add the size of the glyph
Compute the size of the glyph mask, then use _cairo_surface_composite_fixup_unbounded().
Use the right mask format. (Unrelated bugfix)
New function taking a drawing function as a parameter to encapsulate shared logic between compositing trapezoid, glyphs, and masks.
Use _cairo_gstate_clip_and_composite(). Also fix extents computations for unbounded operators.
src/cairo-clip.c src/cairo-clip-private.h (_cairo_clip_combine_to_surface): Add the destination as an extra parameter to allow combining to an intermediate surface.
tests/unbounded-operator.c tests/Makefile.am: Add a test for the operation of the 6 unbounded operators against different shapes.
tests/clip-operator.c tests/Makefile.am: Add a test that tests surface clipping with different shapes against all the operators.
Make use OVER like the name and description. With fixed semantics, SOURCE does something different.

functions and put them in cairo-clip.c.
Rewrite to use new cairo_clip_t functions for manipulating the clip state, change the clip_and_composite_trapezoids call tree to use cairo_clip_t instead of cairo_gstate_t.
Use new cairo_clip_t function to maintain clip state while replaying.
Pass fill rule and tolerance directly, to break gstate dependency.
New function. Set the clip for a surface as specified by the cairo_clip_t.
Move translate_traps() from cairo-gstate.c to here and rename it.
