GEGL (Generic Graphics Lib) is a graph based image processing framework.
Original design was made to scratch GIMP‘s itches for a new compositing and process core and this core is being designed to have minimal dependencies. and a simple well defined API.

Features

• Output in RGB, CIE Lab and Y’CbCr color models with 8bit, 16bit integer and 32bit floating point per component. Possible to extend to ICC managed output in babl.
• Non destructive editing
• C, C#, Python and Ruby interfaces.
• Extendable through plug-ins.
• XML serialization format (not-finalized)
• Iterative processing.
• Efficient subregion evaluation.
• Per node caches.
• Processing and display of image buffers larger than RAM
• Internal sparse pyramidial render cache.
• Bounding box based hit detection.
• Rich core set of processing operations that internally computes with 32bit floating point, linear light RGB.
  • PNG, JPEG, SVG, EXR, RAW, ffmpeg and other image sources.
  • Pattern renderers
  • Arithmetic operations
  • porter duff compositing
  • SVG filter modes and full set of compositing ops from SVG-1.2 draft
  • Gaussian blur, bilateral-filter, symmetric nearest neighbour, unsharp mask.
  • Color correction.
  • Text layout using pango
