GEGL-0.1.0

[Øyvind Kolås-2]

GEGL 0.1.0
⎺⎺⎺⎺⎺⎺⎺⎺⎺⎺
GEGL (Generic Graphics Library) is a graph based image processing framework.

GEGL provides a graph based API and framework to do demand driven, cached, non
destructive image editing of larger than RAM images. Through babl it provides
support for a wide range of color models and pixel storage formats for input
and output.

This is the first release in the 0.1.x development series, APIs have been
overhauled the graph API is now considered pretty stable. Note that to
migrate existing 0.0.x series code to 0.1.x you need to prefix operation
names with "gegl:"

To build gegl-0.1.0 you will also need the newest version of babl.

Changes in this release
⎺⎺⎺⎺⎺⎺⎺⎺⎺⎺⎺⎺⎺⎺⎺⎺⎺⎺⎺⎺⎺⎺⎺
 • Renamed gegl:load-buffer to gegl:buffer-source and gegl:save-buffer
   to gegl:buffer-sink (but the old names still work)
 • Represent colors using doubles instead of floats (this change is
   independent from internal processing)
 • Removed the GTK+ UI parts of the gegl binary and turned gegl into a
   pure command line tool (which can still visualize stuff with help
   help the SDL based display operation)
 • Consider {x=G_MININT/2, y=G_MININT/2, width=G_MAXINT, height=G_MAXINT}
   as the only valid region wichin processing may occur. Processing
   outside of this region is undefined behaviour.
 • Added support for storing allocation stack traces for GeglBuffers
   so that debuging buffer leaks becomes much easier
 • Made small changes and cleanups of the public API, e.g.
   • Removed gegl_node_adapt_child()
   • Made GeglConfig an explicit object
   • Removed most of the ifdeffed stuff to mask away internal
     structures
   • Added gegl_rectangle_infinite_plane() and
     gegl_rectangle_is_infinite_plane()
 • Added new sampler GeglSamplerSharp
 • Added format property go gegl:buffer-sink
 • Cleaned up and made gegl:introspect work again
 • Add a bunch of test cases using the automake test sytem (make check)
   and also port buffer tests to automake
 • General cleanups, bug fixes, increased robustness and improved
   documentation

Congratulations to this release. Will the gegl.org web-site be updated
anytime soon?

Note to all users of GIMP 2.6: The gimp-2.6 releases that we have done
so far will not work with GEGL 0.1.0 (or babl 0.1.0). This is not
because GEGL would be incompatible, but rather because of a stupid bug
in the run-time version check. This is fixed in git and we plan to do
GIMP 2.6.7 release with this fix soonish. There are however a few more
patches pending that we'd like to get into 2.6.7 as well. So give us a
few more days...


Sven

Any update on a GEGL 1.0 compatible GIMP 2.6.7?

Still in the queue and the number of pending patches is going down...
