- Improved performance in case of surface conversion: allocate a shadow buffer that can only grow - Fixed support for small surfaces (less than 8x8) - Optimize the blending function according to the surface format - Added _directfb_categorize_operation(): selects the blitting function according to the transform matrix - Avoid inverting the matrix when doing a simple StretchBlit() - Use TextureTriangles() instead of StretchBlit() when scale factors are negative - Added support for ARGB32 fonts (converted to A8 internally) - Removed unused functions (flush() and mark_dirty_rectangle()) - Code cosmetics |

Cairo - Multi-platform 2D graphics library http://cairographics.org What is cairo ============= Cairo is a 2D graphics library with support for multiple output devices. Currently supported output targets include the X Window System, win32, and image buffers, as well as PDF, PostScript, and SVG file output. Experimental backends include OpenGL (through glitz), Quartz, XCB, BeOS, OS/2, and DirectFB. Cairo is designed to produce consistent output on all output media while taking advantage of display hardware acceleration when available (for example, through the X Render Extension). The cairo API provides operations similar to the drawing operators of PostScript and PDF. Operations in cairo include stroking and filling cubic Bézier splines, transforming and compositing translucent images, and antialiased text rendering. All drawing operations can be transformed by any affine transformation (scale, rotation, shear, etc.). Cairo has been designed to let you draw anything you want in a modern 2D graphical user interface. At the same time, the cairo API has been designed to be as fun and easy to learn as possible. If you're not having fun while programming with cairo, then we have failed somewhere---let us know and we'll try to fix it next time around. Cairo is free software and is available to be redistributed and/or modified under the terms of either the GNU Lesser General Public License (LGPL) version 2.1 or the Mozilla Public License (MPL) version 1.1. Where to get more information about cairo ========================================= The primary source of information about cairo is: http://cairographics.org/ The latest releases of cairo can be found at: http://cairographics.org/releases Snapshots of in-development versions of cairo: http://cairographics.org/snapshots The programming manual for using cairo: http://cairographics.org/manual Mailing lists for contacting cairo users and developers: http://cairographics.org/lists Answers to some frequently asked questions about cairo: http://cairographics.org/FAQ Compiling ========= See the INSTALL document for build instructions. 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. Since the original development, many more people have contributed to cairo. See the AUTHORS files for as complete a list as we've been able to compile so far.
