Snapshot 1.1.6 (2006-05-04 Carl Worth <cworth cworth org>)
==========================================================
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.

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.
