is to test both a COLOR_ALPHA and a COLOR content for each surface backend, (since the semantics are different and we probably need to support both in each backend.
The PS/PDF backends don't allow a content to be passed in right now, so they fail against the rgb24 tests, but the trivial addition to the constructors will allow them to pass all tests with both content values.
And new constructors (currently internal only) to create an image surface with a cairo_content_t rather than a cairo_format_t.
Add a cairo_content_t argument to the constructor.
Add a cairo_content_t to the constructor and use this content value when constructing intermediate image surfaces in acquire_source, show_page, copy_page, and snapshot.
Add image flattening by compositing over white, as is done in cairo-ps-surface.c.
Track changes to cairo-paginates-surface which now requires a cairo_content_t value (no change to public PS/PDF constructors yet).
Track change in meta-surface and paginated-surface interfaces by now accepting a cairo_content_t rather than a cairo_format_t.
Ignore new output files (argb32 from pdf and ps as well as rgb24 from test-fallback, test-meta, and test-paginated).
Add new utility for flattening PNG images in order to generate the -argbf-ref.png images.
Add image_diff_flattened for comparing flattened output from PS and PDF backend with ARGB reference images by first blending the reference images over white.
Get rid of conditional, format-specific background-color initialization before running tests. Now uses ARGB(0,0,0,0) in all cases. Switch from specifying tests with a format value to specifying tests with a content value. Add support for a 'fake' COLOR_ALPHA_FLATTENED content for testing the PS and PDF output against a flattened version of the argb32 reference images (first blended over white).
Track change in cairo_ps_surface_create (now requires cairo_content_t value).
Adjust tests that draw in default (black) to first paint white so that the results are visible.
Adjust ARGB32 reference images for new white background for changed tests.
Adjust RGB24 reference images for new black background due to changed initialization (and the tests themselves being unchanged).

Conventions Specification. Thanks to Michael Sweet for bringing several items to our attention. Things that are fixed: Add Pages: (atend) to header, add Pages: N to trailer, properly advertise DocumentData of Binary rather than Clean7Bit, remove fictitious EndPage, move showpage to after the grestore.

using ARGB32. It turns out that the PS backend already has its own blend-with-white code, and the test-paginated-surface really wants ARGB32.

internals of cairo_array_t changed on 2005-12-21. Now, hopefully less than all text will be broken on win32.

the test suite.
Fix broken implementation of copy_page in the paginated surface by hiding it from the target surface which sees only show_page operations. (It's hard to do better than that unless we can guarantee thathe subsequent page won't trigger any image fallbacks.)
|
|
Remove backend-specific tests (ps-surface, pdf-surface, and pdf-clip) that are now redundant with the ps and pdf support in the rest of the test suite.
Add a new one-off test for testing show_page with both the ps and pdf backends.
|
|
cairo_ps_surface_t (at least):
Move the Y-axis-flipping to be on a per-page basis (as it was before and as it must be). Put page number back in, (still missing th number of pages from the header).
Add multi-page output for better testing.

to preserve default white background instead of forcing a black background instead.

cairo_paginated_surface_t.
Switch from ARGB32 to RGB24 for intermediate image surface since that's all that the current users of cairo_paginated_surface support anyway.
Switch cairo_ps_surface_t over to use the new cairo_paginated_surface_t. This drastically simplifies the implementation, but temporarily puts the PostScript output back into the land of one-image-per-page. To be fixed soon though with improvements to cairo_paginated_surface_t. Everything still passes the test suite which is good. The test suite currently does no testing of multi-page output, which is quite bad.

test suite!
Add new functions needed by users of cairo_paginated_surface_t.
Always snapshot a paginated surface to an image surface, rather than a surface similar to the target. We do this since paginated target surfaces are allowed to not be complete surfaces, (such as not implementing acquire_source_surface).
Switch the implementation of cairo_pdf_surface_t to use cairo_paginated_surface_t. For now this means that all PDF output is fallback images, but this can change incrementally as we go forward.
|
|
(_cairo_atsui_font_set_metrics): Fix descent calculation.
|
|
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.
|
|
|
|
|
|
Change the paginated surface to force all output to come from an image surface (to be refined incrementally as we hook real surface backends up to it).
|
|
Implement copy_page for paginated surface. Fix show_page to destroy the meta-surface and create a new one.
Change these functions to advertise when they are not supported, so that _cairo_paginated_copy_page can implement things differently depending on whether or not it is personal.
Check return values from _cairo_surface_show/copy_page.

incorporated into the test suite and is only failing two tests (self-copy and trap-clip). Note new progress on cairo_push/pop_group. Add item to support pango's hex-box drawing. Note that gradient computation performance has been improved. Note that experimental SVG backend has been added.

Throw away old gradient code from within cairo-pattern.c in favor of using new support in pixman for gradients.
Update reference images for all tests involving gradients since the gradient output has changed slightly.
|
|
Some major performance improvements to the general composite code used for gradients and transformed images. Like fetching of mask scanline before source scanline so that only the necessary pixels from source needs to be computed in case of gradients or transformed images as source. This patch also include some gradient specific fixes and performance improvement.
|
|
Add entries for gradient support.
Add PictureGradientColor.
Add necessary functionality for gradient support.
Enable gradient support.

(_cairo_glitz_surface_get_image): Set the glitz clip to NULL before calling glitz_get_pixels, to return the full surface contents. Restore clip afterwards. (_cairo_glitz_surface_composite_trapezoid): Return UNSUPPORTED if the antialias is anything other than DEFAULT/GRAY.
Try to recover a standard cairo_format_t from given pixman format masks, so that various things that only work with a standard format work correctly.
Remove cairo_glitz_surface_write_to_png, replace with generic cairo_surface_write_to_png (since it works with image-surface create_with_masks fix)

pass/fail squares.

(_cairo_surface_intersect_clip_path): a NULL path means reset of clipping region, not back to previous clipping level.

This was slowing things down a _lot_ (about 11× for the mask test for example) without any improvement in output quality. We can revisit this again later if there's any output improvement to be had down the road.

surface and is intended to provide an easy interface with common functionality for the various paginated surface types (ps, pdf, etc.).
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.

previously committed inadvertently.
Fix buggy implementation of _cairo_array_snapshot by changing array->elements to be a pointer to a pointer. This extra level of indirection allows the snapshot array to point to a pointer which will itself get changed when new storage is needed for a growing array. Previously, the snapshot would be left pointing at stale storage.
Fix to call _cairo_array_index rather than grabbing array->elements directly and casting (which cast is now wrong with the change in implementation of array->index).

Remove unused _test_fallback_surface_create_for_data.
Remove unused _test_meta_surface_create_for_data. Add missing source file src/test-meta-surface.h.

the former is guaranteed to work with all backends.
Refine the comment describing this test surface.
Add new test surface for exercising cairo_meta_surface.
Simplify the image and test_fallback targets by not using create_for_data. Allow for NULL cleanup target functions. Add support for the test_meta_surface.
