cairo_set_pattern -> cairo_set_source cairo_get_pattern -> cairo_get_source cairo_set_rgb_color -> cairo_set_source_rgb
-> cairo_set_source_rgba cairo_set_alpha -> cairo_get_alpha ->
Note that we'll likely want to add cairo_set_source_surface.
Add _cairo_stock_color helper function. Improve some interfaces:
_cairo_color_init _cairo_color_init_rgb _cairo_color_set_rgb -> _cairo_color_init_rgba _cairo_color_set_alpha _cairo_color_multiply_alpha
_cairo_color_get_rgb -> _cairo_color_get_rbga _cairo_color_get_rgba_premultiplied
Add cairo_stock_t and some helper macros:
CAIRO_COLOR_WHITE CAIRO_COLOR_BLACK CAIRO_COLOR_TRANSPARENT
Fix cairo_pattern_t by eliminating pattern->alpha. Fix cairo_solid_pattern_t to use cairo_color_t rather than three doubles.
Track removal of pattern->alpha, simplifying the code considerably
Track _cairo_color interface changes. Remove gstate->alpha. Propagate down set_source renamings.
cairo_pattern_add_color_stop -> cairo_pattern_add_color_stop_rgba
and add:
cairo_pattern_add_color_stop_rgb
Remove pattern->alpha, simplifying the code considerably.
Track pattern and color interface changes.
Add const where appropriate on cairo_color_t*.
Add private type inspection predicate. (cairo_xlib_surface_set_size): Add check for surface type mismatch, (no useful error reporting yet, though).
Note coverage as en expected failure.
Improve line wrap on expected failure messages.
Port all tests to new cairo_set_source interfaces.

369d1bf28f Default to CAIRO_FILTER_GOOD rather than CAIRO_FILTER_BEST.
Optimize to use CAIRO_FILTER_NEAREST when the pattern matrix is an integer translation.

d135938efd Rework the cairo_matrix_t interface in several ways. Expose a struct for cairo_matrix_t.
Add new function to return current matrix: cairo_get_matrix
Deprecate the following functions (in documentation): cairo_matrix_create cairo_matrix_destroy cairo_matrix_get_affine
Rename: cairo_matrix_set_affine -> cairo_matrix_init cairo_matrix_set_identity -> cairo_matrix_init_identity
Add other new matrix initialization functions: cairo_matrix_init_translate cairo_matrix_init_scale cairo_matrix_init_rotate
Change return type of almost all cairo_matrix functions from cairo_status_t to void.
Track changes to cairo_matrix_t interface.
Add a test case showing the same path drawn under various transforms, (including skews set directly by initializing a cairo_matrix_t).

a6d9b6a671 Change type of data parameter from char* to unsigned char*.
Propagate the unsigned char* change down the stack.
Add cast since XImage uses char* rather than unsigned char*.
Fix memory leak of image data.
Switch to use cairo_surface_write_png rather than a custom write_png_argb32.
Add test to exercise the cairo_image_surface_create_for_png function.

e7607bb379 Comment and clean up the gradient computation. (_cairo_linear_pattern_classify): Determine if a linear gradient is horizontal or vertical. (_cairo_pattern_acquire_surface_for_gradient): Optimize horizontal/vertical gradients with a repeating surface.
Test case for linear gradients at angles and with a rotated pattern matrix.

1a043bbf26 Don't put an off-by-one n_stops into cairo_shader_op_t. (_cairo_shader_op_find_color_stops): Put search for two color stops containing a given offset into its own function. Handle the case of before first and after last stop by returning the nearest stop twice. (_cairo_pattern_calc_color_at_pixel): Handle case of no color stops by returning a transparent pixel. 2005-02-25 12:52:47 +00:00

c8a98b109a Fix y offset to use dst_y instead of dst_x, (caught by David Reveman). 2005-02-21 08:17:42 +00:00

26148a1d15 src/cairoint.h src/cairo_image_surface.c src/cairo_pdf_surface.c src/cairo_png_surface.c src/cairo_surface.c src/cairo_xlib_surface.c: Replace the get_image()/set_image() backend operations with a more specific {acquire,release}_{source,dest}_image() and clone_similar().
src/cairoint.h src/cairo_pattern.c: Replace _cairo_pattern_get_surface() with a _cairo_pattern_begin_draw()/_cairo_pattern_end_draw() pair.
Save the format for which an image is created so we can access it later. (Needed for the _cairo_xlib_surface_clone_similar())
src/cairoint.h src/cairo_image_surface.c: Add _cairo_surface_is_image().
Add CAIRO_OK(status) to check for CAIRO_STATUS_SUCCESS.
In the absence of of RENDER, make cairo_xlib_surface_create_similar() return an image surface.
Don't try to use RENDER to composite glyphs in the absence of the RENDER extension.

dca785faaf Fixes from David Reveman:
Don't save to surface part of the union when the pattern isn't a surface pattern. (_cairo_pattern_get_surface): Create the new surface at the width and height of the source.
Add cairo-ft-private.h

a24f2f909e Update prototype to eliminate warning.
Remember to reference surfaces when copying patterns.
Don't call _gstate_create_pattern for internally created patterns. (_cairo_gstate_show_surface): Don't change the surface matrix here, it's done later when we set it up as a pattern.
Correct clip_twice-ref.png filename.
Add these.
Fix broken intersection code.

79c8b29c3b Fold _cairo_pattern_get_image into _cairo_pattern_get_surface and make sure we always return a surface of the same type as dest.
Use _cairo_pattern_get_surface instead of _cairo_pattern_get_image.
Remove use of _cairo_xlib_surface_clone_similar since _cairo_pattern_get_surface always gives us an xlib surface for the pattern. Clean up error handling code in _cairo_xlib_surface_show_glyphs.
Add missing cairo_surface_destroy and tidy up offset calculations as suggested by Owen.
Simplify code for computing the extents of clipping area, by introducing a couple of cairo_rectangle_t functions.

17ec6f1482 The overall idea of this rewrite is that we want to pass the source pattern all the way down into the backends. The motivation for this is that not all backends want a surface for the source operand, and by passing the pattern down, backends can choose to convert it to a surface if they need that.
The patch removes the create_surface function pointer from the surface vtable and moves much of that code into a couple of helper functions. The composite, compsite_trapezoids, and show_glyphs backend functions are updated to take a cairo_pattern_t instead of a surface as the source.
Change these functions to not create a surface for the pattern and just pass the pattern down to the backend functions.
New function to translate a set of trapezoids.
Break out the code to adjust and restore surface transformation and repeat settings into _cairo_pattern_prepare_surface and _cairo_pattern_restore_surface.
Split cairo_pattern_create_for_surface into an init function and a create function.
Utility functions to create a surface from a pattern.
Update these backends to work with the new pattern API. Glitz work by David Reveman.
Update these to pass through the new set of args.
Update this reference image as we now render it correctly.
