Snapshot 0.1.21 (2004-04-09 David Reveman <c99drn@cs.umu.se>)
=============================================================
New OpenGL backend
------------------
The OpenGL backend provides hardware accelerated output for
X11 and OS X. The significant new functions are:
cairo_set_target_gl
cairo_gl_surface_create
Automatic detection of available backends
-----------------------------------------
The configure script now automatically detect what backends are
available, (use ./configure --disable-`backend' to prevent
compilation of specific backends).
Snapshot 0.1.20 (2004-04-06 Carl Worth <cworth@isi.edu>)
========================================================
New pattern API
---------------
David Reveman has contributed a new pattern API which enable linear
and radial gradient patterns in addition to the original surface-based
patterns. The significant new top-level functions are:
cairo_pattern_create_linear
cairo_pattern_create_radial
cairo_pattern_create_for_surface
cairo_pattern_add_color_stop
cairo_set_pattern
Any code using the old cairo_set_pattern, (which accepted a
cairo_surface_t rather than a cairo_pattern_t), will need to be
updated.
Update to XCB backend
---------------------
The XCB backend is now enabled by default, (use ./configure
--disable-xcb to turn it off).
Faster clipping
---------------
Graydon Hoare has added optimizations that make cairo_clip much faster
when the path is a pixel-aligned, rectangular region.
Bug fixes.
Snapshot 0.1.19 (2004-02-24 Carl Worth <cworth@isi.edu>)
========================================================
New PNG backend
---------------
Olivier Andrieu contributed a new PNG backend. It builds on the
existing image backend to make it easy to render "directly" to a
.png file. The user never needs to deal with the actual image
buffer. The significant new functions are:
cairo_set_target_png
cairo_png_surface_create
The PNG backend is not enabled by default so that by default there is
not a new dependency on libpng. Use ./configure --enable-png to enable
this backend.
Snapshot 0.1.18 (2004-02-17 Carl Worth <cworth@isi.edu>)
========================================================
Path query functionality
------------------------
It's now possible to query the current path. The two new functions
are:
cairo_current_path
cairo_current_path_flat
Each function accepts a number of callback functions that will be
called for each element in the path (move_to, line_to, curve_to,
close_path). The cairo_current_path_flat function does not accept a
curve_to callback. Instead, all curved portions of the path will be
converted to line segments, (within the current tolerance value). This
can be handy for doing things like text-on-path without having to
manually interpolate bezier splines.
New XCB backend
---------------
Jamey Sharp has contributed a second X backend that uses the new, lean
XCB library rather than Xlib. It cannot currently be compiled at the
same time as the Xlib backend. See ./configure --enable-xcb.
Build fixes for cygwin.
Bug fixes.
Snapshot 0.1.17 (2003-12-16 Carl Worth <cworth@isi.edu>)
========================================================
Better text support
-------------------
This snapshot provides much better text support by implementing the
following four functions:
cairo_text_extents
cairo_glyph_extents
cairo_text_path
cairo_glyph_path
The text/glyph_extents functions can be used to determine the bounding
box (and advance) for text as if drawn by show_text/glyphs.
The text/glyph_path objects functions place text shapes on the current
path, where they can be subsequently manipulated. For example,
following these functions with cairo_stroke allows outline text to be
drawn. Calling cairo_clip allows clipping to a text-shaped region.
Combined dependencies
---------------------
The cairo core now depends only on the libpixman library. This single
library replaces the three previous libraries libic, libpixregion, and
slim. Thanks to Dave Beckett <dave.beckett@bristol.ac.uk> for all of
the heavy lifting with this renaming effort.
Conditional compilation of backends
-----------------------------------
Cairo now allows optional beckends to be disabled at compile time. The
following options may now be passed to the configure script:
--disable-xlib
--disable-ps
Note that the first option is a change from the old --without-x option
which will no longer have any effect.
OS X supported - several byte-order issues resolved
---------------------------------------------------
Cairo has now been successfully compiled under OS X. Testing revealed
that there were some byte-order problems in the PostScript backend and
the PNG generation in the demos. These have now been resolved.
2003-10
=======
Graydon Hoare <graydon@redhat.com> implemented the first real text
support using Freetype/fontconfig, (previous versions of cairo used
Xft and could only draw text when using an X backend).
2003-09
=======
Graydon Hoare <graydon@redhat.com> added the first real support for
running cairo with a non-render-aware X server.
Jamey Sharp <jamey@minilop.net> virtualized the backend font and
surface interfaces in September, 2003.
2003-06
=======
Xr is renamed cairo to avoid confusion since it no longer had a strict
dependence on X.
2003-05
=======
A new image surface backend is added to Xr. Keith Packard
<keithp@keithp.com> wrote the image compositing code in libic that is
used for the image_surface backend. This code was originally written
as the software fallback for the render extension within the X
server.
2002-06
=======
Carl Worth <cworth@isi.edu> wrote the first lines of Xr, after Keith
Packard <keithp@keithp.com> proposed the plan for a stateful drawing
library in C providing a PostScript-like rendering model.
