We had several pdf tests disabled waiting for this bug fix: Poppler does not correctly handle knockout groups https://bugs.freedesktop.org/show_bug.cgi?id=12185 That's in place for poppler now, so we're turning the tests back on. Some of the affected tests now pass perfectly: over-above-source over-around-source over-below-source over-between-source Some just needed new reference images: operator-clear clip-operator-pdf-argb32 The remaining tests still fail, but none of the failures can obviously be ascribed to just poppler problems: clip-operator-pdf-rgb24 operator-source unbounded-operator The first two have some serious problems, while in the case of unbounded-operator the problem is extremely minor (a white grid appears in the background where the reference image is all black). |

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 versions of cairo can always be found at: http://cairographics.org/download Documentation on using cairo and frequently-asked questions: http://cairographics.org/documentation http://cairographics.org/FAQ Mailing lists for contacting cairo users and developers: http://cairographics.org/lists Roadmap and unscheduled things to do, (please feel free to help out): http://cairographics.org/roadmap http://cairographics.org/todo 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.
