This test exercises the combination of cairo_get_group_target along
with cairo_surface_get_device_offset. Something funny is currently
going on with the surfaces based on the paginated surface.
Specifically, device offsets now affect using the offset surface in
a source pattern as well as drawing to the surface. This behavior
os also verified with a new test case: test/device-offset.c
This patch adds the following API calls:
cairo_push_group
cairo_push_group_with_content
cairo_pop_group
cairo_pop_group_to_source
cairo_get_group_target
These methods support implementing layers on top of a cairo context,
allowing for drawing with transparency and temporary buffering.
cairo_get_group_target allows an app to get access to the actual surface
created by the last push_group call, in case itneeds to perform native
drawing to it.
Add a new cairo_ps_surface_set_size which can be used to produce a
PostScript file consisting of pages of various different sizes (or
orientations).
Also add a new test (ps-features.c) for testing this and subsequent
ps-specific function calls.
Add a new cairo_test_paint_checkered function so that tests that draw
with alpha can easily put an easy-to-see checkered background in place
first.
Add new tests caps-joins-alpha and paint-source-alpha that do simple
tests of strokes and image painting with source pattern alpha.
Also, add the checkered background to paint-with-alpha for
consistency.
This adds a new function which has as its only effect the elimination
of
the current point. This makes it much easier to use the various
cairo_arc calls when the initial line_to is not actually desired.
This function also unifies and generalizes the long-existing behavior
of cairo_line_to being treated as cairo_move_to when there is no
current point. With the addition of cairo_new_sub_path this becomes a
documented feature with similar behavior in cairo_curve_to as well.
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).
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_svg_surface_t owns a xml node, for support of svg_surface_composite. (_cairo_svg_surface_create_for_document): init xml_node. All surfaces except first one are stored in defs node. (emit_composite_image_pattern): returns pattern size, and don't call emit_transform if is_pattern == TRUE. (emit_composite_svg_pattern): do something. (emit_composite_pattern): returns pattern size. (_cairo_svg_surface_composite): xml_node is stored in cairo_svg_surface_t now. (emit_surface_pattern): emit surface pattern width here. Fix property names. (_cairo_svg_path_close_path): don't close path if no current point. (_cairo_svg_surface_fill_rectangles): new. (_cairo_svg_surface_fill): emit fill rule. xml_node is in surface now. (_cairo_svg_surface_composite_trapezoids): xml_node is in surface now. (_cairo_svg_surface_stroke): ditto. (_cairo_svg_surface_intersect_clip_path): ditto. Emit fill rule.
