cairo_path.last_move_point and cairo_path.current_point are now fixed-point not doubles for consistency. Now accept 4 explicit function pointers rather than a structure. Eliminate unnecessary done_path callback. Track change in _cairo_path_interpret. Code previously in done_path callback is now here immediately after call to _cairo_path_interpret. Internal _cairo_path API modified to accept fixed-point data everywhere. Much cleaner this way. Have to convert doubles to fixed-point to track changes in _cairo_path API. Keep data in fixed-point rather than going through intermediate doubles. Track changes in _cairo_path API. New function to help when working with freetype. |

Cairo - Multi-platform 2D graphics library 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@isi.edu> 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
