Why don't we just work on this together? The way it is now is that you
confront me with a bunch of patches without having talked to me and
without explaining their purpose. From a quick look I can see that there
are some useful changes in there but also some things that need to be
done differently. We could avoid a lot of duplicated efforts and wasted
time on both sides if you would ask beforehand and work more closely
with me. I would be more than happy to get some help with color
management. After all it's the major blocker for 2.4 at the moment.

[Gimp-developer] GEGL 0.0.12

2007-02-18 Thread Øyvind Kolås
GEGL 0.0.12
⎺⎺⎺

GEGL is a graph based image processing framework offering non-destructive image
processing and compositing on large images. GEGL is suitable for projects
ranging from small one-off projects to interactive applications.


Changes in this release
⎺⎺⎺
 • Swapping out of image pyramid.
 • Speedups to text rendering.
 • GEGL compiles on win32
 • GEGL_SWAP now specifies swapdir location.
 • Small refactorings of public API.
 • Changed the XML parser/serializer to not use attributes for node properties.
 • Improvements to documentation.
 • Automagic build environment for operations simplified.
 • Internal API for saving/loading GeglBuffers to/from disk.
 • Ruby, C# and Python bindings added to version control system
   (not included in distributed tarball)

A new release of babl is also available that fixes the reference
conversion from premultiplied to non-premultipled data making it
work on platforms where the dynamically loaded performance extensions
do not work yet.

Contributions from:

Kevin Cozens, Øyvind Kolås, Sven Neumann and Michael Schumacher.

When will GEGL finally be implemented in the Gimp? 16-bit support was
already mentioned in 2002, and newer apps like 'Krita' have already
32-bit/HDR. To me, 16-bit  color management are most important;
otherwise users will simply switch to other apps. I don't want the Gimp
to become a second Photoshop, and I really like using it, but the lack
of 16-bit are something that keeps especially pro users from using the
Gimp.
