gegl-0.1.2

GEGL 0.1.2
??????????
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.

To build gegl-0.1.2 you will also need babl-0.1.2

Changes in this release ???????????????????????
• GeglLookup, configurable floating point lookup tables for lazy computation. • Use GFileIOStream in GeglTileBackendFile. • Optimizations: in-place processing for point filters/composers, SIMD version of gegl:opacity, avoid making unneccesary sub-buffers, removed some manual instrumentation from critical paths, improved speed of samplers. In some cases with current GIMP this leads to a doubling of the performance.
• Added xml composition/reference image based regression tests. • Added performance tracking framework. • Syntactic sugar using varargs for constructing gegl graphs from C. • Build fixes on cygwin,
• Gegl# fixes.
• Initial, but unstable code towards multithreading. • Improvements to lua op in workshop. • Added new resamplers upsize, upsharp, upsmooth, downsize, downsharp and downsmooth.
• Removed gegl:tonemap and gegl:normal ops.
