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. |

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
