* Drop cairo_default_matrix since it is now always identical to ↵Carl Worth2005-04-041-8/+0
| | | | | | | cairo_identity_matrix. Remove gstate->pixels_per inch. Change default matrix to always be the identity matrix. Drop pixels_per_inch function from surface backend interface as it is no longer needed.
* Style and indentation fixes.Carl Worth2005-04-021-1/+1
| | | | | | | cast to quiet new gcc-4 warnings. Initialize variables to quiet new gcc-4 warnings. Use unsigned char* as expected by freetype, libpng, Xlib, and zlib. Propagate unsigned char* down from cairo_text_extents.
* Update API shakeup chart.Carl Worth2005-04-011-0/+1
| | | | | Add a standin for the function that should be cairo_set_target_image which should then have some other name. We can straighten that mess out when we eliminate the set_target functions. Add deprecation alias for cairo_current_pattern. Deprecate cairo_surface_create_for_image in favor of cairo_image_surface_create_for_data.
* Add cairo_output_stream.cKristian Høgsberg2005-03-161-4/+4
| | | | | | | | | | Add new errors, CAIRO_STATUS_WRITE_ERROR and CAIRO_STATUS_SURFACE_FINISHED, add cairo_surface_finish() prototype, add cairo_write_func_t. Add strings for new errors, documentation fix. Rename surface destroy functions to finish and change them to not free the surface. Change PDF surface constructors to take a write function in the general case and add stdio convenience constructors. Change destroy function to finish for cairo_pdf_surface. Change implementation to use cairo_output_stream_t functions for output. Use _cairo_surface_show_glyphs instead of calling function pointer directly. Add prototypes for cairo output stream functions, rename destroy to finish in cairo_surface_backend_t and add finished flag to cairo_surface_t. Add cairo_surface_finish() and call it from cairo_surface_destroy(). Check the finished flag in cairo_surface_t in functions that change the surface.

* src/cairoint.h src/cairo_image_surface.c src/cairo_pdf_surface.c ↵Owen Taylor2005-01-311-46/+114
| | | | | | | | | | | 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.
* Fold _cairo_pattern_get_image into _cairo_pattern_get_surface and make sure ↵Kristian Høgsberg2005-01-271-11/+20
| | | | | | | | | 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.
* The overall idea of this rewrite is that we want to pass the source pattern ↵Kristian Høgsberg2005-01-271-34/+45
| | | | | | | | | | | | | | 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.
* Change return value from cairo_status_t to cairo_int_status_t to match ↵Carl Worth2004-12-201-1/+1
| | | | definition in cairo_surface_backend_t.
* Change the signs of a variety of metrics, which were backwards.Graydon Hoare2004-11-051-2/+2
| | | | | Return early if we found a rectangular clip at all, not just in error case. Give render glyphset entry the negative bbox offsets it wants, not the bearings.
* Convert all files to utf-8. Add copyright information to cairo_png_surface.c.Carl Worth2004-10-211-1/+1
