GEGL image processing
---------------------
- Floating point handling and processing and output of larger 8bit,
16bit integer and 32bit floating point per component buffers larger
than RAM.
- C based, object oriented API with introspection support for dynamic
languages like python, ruby, javascript and php.
- Processing
* Iterative chunk-wise processing.
* Processes subregions and dependencies.
* Subgraph caches to aid performance of non-destructive editing.
* Multi-threaded processing.
* OpenCL acceleration, capable of hybrid cpu/gpu processing.
* Experimental mipmap preview rendering, do zoomed out preview
rendering touching only 25% 6.25% of the pixels.
- GeglBuffer
* Storage of all babl supported formats.
* Sparse swapped buffers (larger than RAM images).
* linear buffers (allocated internally or from external
allocation).
* On demand tiled mipmapping.
* Thread-safe reading/writing.
* External tile-backends (allow wrapping other tiled buffer systems
to use them through the GeglBuffer API).
* Most operations operate in
http://en.wikipedia.org/wiki/ScRGB_color_space[scRGB] (using
32bit floating point/HDR linear light RGBA), operations use babl
formats to specify whether data should be linearized for
processing.
- Bounding box based hit detection.
- XML serialization format (not-finalized)
