From: Carl Worth <firstname.lastname@example.org> Date: 4 May 2006 To: email@example.com Cc: firstname.lastname@example.org Subject: [cairo-announce] cairo snapshot 1.1.6 now available A new cairo snapshot 1.1.6 is now available from: http://cairographics.org/snapshots/cairo-1.1.6.tar.gz which can be verified with: http://cairographics.org/snapshots/cairo-1.1.6.tar.gz.sha1 6c2c5dc688edca44f8087b6ffe8bfc1b7b1c3ba1 cairo-1.1.6.tar.gz http://cairographics.org/snapshots/cairo-1.1.6.tar.gz.sha1.asc (signed by Carl Worth) Additionally, a git clone of the source tree: git clone git://git.cairographics.org/git/cairo will include a signed 1.1.6 tag which points to a commit named: 7ba3b75efd56113411ed141a86675099ae82d5d5 which can be verified with: git verify-tag 1.1.6 and can be checked out with a command such as: git checkout -b build 1.1.6 Snapshot 1.1.6 (2006-05-04 Carl Worth <email@example.com>) ========================================================== This is the third in a series of snapshots working toward the imminent 1.2 release of cairo. For a list of items still needing work on the cairo 1.2 roadmap, please see: http://cairographics.org/ROADMAP As can be seen in that list, there are no longer any API additions left on the roadmap. Instead, there is a feature (PDF type 3 fonts) a performance optimization (X server gradients) and a list of bug fixes. This gives us a fair amount of freedom to cut the 1.2 release at almost any point by deciding to defer remaining bug fixes to subsequent maintenance releases such as 1.2.2 and 1.2.4. Before we will do that, we must first be wiling to commit to all the new API additions. As a heads-up, there are a couple of potential API changes being considered. (Note that these are changes to new API introduced during 1.1 so these will not introduce API incompatibilities compared to the stable 1.0 series). The changes being considered are: cairo_get_group_target: may acquire x and y offset return parameters. May also be eliminated in favor of cairo_get_target assuming its role cairo_pdf_surface_set_dpi: cairo_ps_surface_set_dpi: cairo_svg_surface_set_dpi: These functions may be removed in favor of a new cairo_surface_set_fallback_resolution Additionally there is the possibility of a slight change in the semantics of cairo_set_line_width. We believe the current behavior of the sequence: cairo_set_line_width; ... change CTM ...; cairo_stroke; is buggy. It is currently behaving the same as: ... change CTM ...; cairo_set_line_width; cairo_stroke; We are considering fixing this bug before 1.2 with the hope that nobody is already relying on the buggy behavior described here. Do shout if you suspect you might be in that position. This snapshot is backwards-compatible with the 1.0 series---it makes a few API additions but does not remove any API. See a few paragraphs below for details on what's new in 1.1.6. 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. Experimental backends include OpenGL (through glitz), Quartz, XCB, PostScript and PDF file output. 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 including 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 What's new in 1.1.6 compared to 1.1.4 ===================================== API additions ------------- The long-awaited group-rendering support is now available with the following function calls: cairo_push_group cairo_push_group_with_content cairo_pop_group cairo_pop_group_to_source cairo_get_group_target This API provides a much more convenient mechanism for doing rendering to an intermediate surface without the need to manually create a temporary cairo_surface_t and a temporary cairo_t and clean them up afterwards. Add the following missing get function to complement cairo_surface_set_device_offset: cairo_surface_get_device_offset PDF backend (API addition) -------------------------- The PDF backend now provides for per-page size changes, (similar to what the PostScript backend got in the 1.1.4 snapshot). The new API is: cairo_pdf_surface_set_size Xlib backend (API additions) ---------------------------- The following functions have been added to allow the extraction of Xlib surface: cairo_xlib_surface_get_display cairo_xlib_surface_get_drawable cairo_xlib_surface_get_screen cairo_xlib_surface_get_visual cairo_xlib_surface_get_depth XCB backend (experimental) -------------------------- Update backend so that it now compiles with the recent XCB 0.9 release. Bug fixes and memory leak cleanup --------------------------------- Various little things, nothing too significant though.
