<html> <head> <style></style> </head> <body class='hmmessage'> As Ubuntu user, to use cairo I only followed the steps from http://www.cairographics.org/download/ (typed<code> sudo apt-get install libcairo2-dev</code> ) That was one month ago. What would be the way to make use of the latest cairo release? I guess some problems I faced are repaired (or performance improved), and I would be happy to use the latest release.

This is a major update to cairo, with new features and enhanced functionality which maintains compatibility for applications written using any previous major cairo release, (1.8, 1.6, 1.4, 1.2, or 1.0). We recommend that anybody using a previous version of cairo upgrade to cairo 1.10.0. One of the more interesting departures for cairo for this release is the inclusion of a tracing utility, cairo-trace. cairo-trace generates a human-readable, replayable, compact representation of the sequences of drawing commands made by an application. This can be used to inspecting applications to understand issues and as a means for profiling real-world usage of cairo. The traces generated by cairo-trace have been collected in git://git.cairographics.org/git/cairo-traces and have driven the performance tuning of cairo over the last couple of years. In particular, the image backend is much faster with a new polygon rasterisation and a complete overhaul of the tessellator. Not nly is this faster, but also eliminates visual artifacts from self-intersecting strokes. Not only has cairo-trace been driving performance improvements within cairo, but as a repeatable means of driving complex graphics it has been used to tune OpenGL, DDX, and pixman. Cairo's API has been extended to better support printing, notably through the ability to include a single compressed representation of an image for patterns used throughout a document, leading to dramatic file size reductions. Also the meta-surface used to record the vector commands compromising a drawing sequence is now exposed as a CAIRO_SURFACE_TYPE_RECORDING, along with a new surface that is a child of a larger surface, CAIRO_SURFACE_TYPE_SUBSURFACE. One typical usage of a subsurface would be as a source glyph in a texture atlas, or as a restricted subwindow within a canvas. Cairo's API has also resurrected the RGB16 format from the past as the prevalence of 16-bit framebuffers has not diminished and is a fore-taste of the extended format support we anticipate in the future. Increasing cairo's utility, we introduce the cairo_region_t for handling sets of pixel aligned rectangles commonly used in graphics applications. This is a merger of the GdkRegion and the pixman_region_t, hopefully providing the utility of the former with the speed of the latter. Furthermore cairo has been reworked to interoperate more closely with various acceleration architectures, gaining the ability to share those hardware resources through the new cairo_device_t. For instance, with the new OpenGL backend that supersedes the Glitz backend, hardware and rendering operations can be shared between a classic OpenGL application mixing libVA for the hardware assisted video decode with cairo for high quality overlays all within the same OpenGL canvas.

Currently supported output targets include the X Window System, quartz, win32, and image buffers, as well as PDF, PostScript, and SVG file output. Experimental backends include OpenGL, 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.
