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.

4c329eecb9 Make sure we always return a surface similar to dst in the gradient case. 2005-01-27 21:14:04 +00:00

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.
