Add a CAIRO_STATUS_BAD_NESTING error for interleaved use of two cairo_t's on the same surface. Also, add a skeleton doc comment for cairo_status_t. src/cairo.c src/cairo-gstate.c src/cairoint.h: Use _cairo_surface_begin/end to replace _cairo_gstate_restore_external_state. Use _cairo_surface_begin/end to save the state of a surface when we start drawing at it and restore it at the end. Check that the save level of the surface is what we expect on drawing operations and fail with CAIRO_STATUS_BAD_NESTING otherwise. src/cairo-pattern.c src/cairoint.h (_cairo_pattern_acquire_surface_for_surface) (_cairo_pattern_release_surface): Surround use of pattern->surface with _cairo_surface->begin/end so we don't clip surfaces used as sources. test/clip-nesting.c test/Makefile.am: Test of destinatin clipping with the nested creation of cairo_t's for the same context. test/source-clip.c test/Makefile.am: Test that clipping on a source as a destination doesn't affect use of it as a source. XFAIL test for copying from a surface as a source to itself as a destination with a clip. |

Cairo - Multi-platform 2D graphics library http://cairographics.org Compiling --------- See the INSTALL document for build instructions. Description ----------- Cairo is a vector graphics library with cross-device output support. Currently supported output targets include the X Window System and in-memory image buffers. PostScript and PDF file output is planned. Cairo is designed to produce identical output on all output media while taking advantage of display hardware acceleration when available (eg. through the X Render Extension). Cairo provides a stateful user-level API with capabilities similar to the PDF 1.4 imaging model. Cairo provides operations including stroking and filling Bezier cubic splines, transforming and compositing translucent images, and antialiased text rendering. Cairo was once named Xr, (or Xr/Xc), so if you came looking for that software, you've found it. Dependencies ------------ Cairo currently requires the following supporting libraries: libpixman Xft2 fontconfig freetype2 Documentation ------------- There's not much documentation yet apart from the cairo.h header file. We'll be correcting that shortly. In the meantime, the cairo-demo module in CVS provides a few example programs using cairo. These may be helpful to a programmer just beginning with cairo. Also, familiarity with the PostScript imaging model will help in understanding cairo. History ------- Cairo was originally developed by Carl Worth <cworth@cworth.org> and Keith Packard <keithp@keithp.com>. Many thanks are due to Lyle Ramshaw without whose patient help our ignorance would be much more apparent. Mailing List ------------ If you have trouble with cairo or you have some ideas for how it could be improved, please feel free to send a message to cairo@cairographics.org Cairo is still under active development and all discussion happens on that list. So if you want to lurk or, (even better), take part in the development, take a look. Subscription information and archives are available: http://cairographics.org/cgi-bin/mailman/listinfo/cairo
