GEGL (Generic Graphics Library) is a graph based image processing framework.
With GEGL you chain together image processing operations represented by nodes into a graph. GEGL provides such operations for loading and storing images, adjusting colors, filtering in different ways, transforming and compositing images.

- Further pointers for development
Miscellaneous notes about possible ways of building and developing with GEGL.
If you read this on the gegl.org website you are reading the snapshot of the documentation generated for gegl at that point. For further information here are some pointers to follow:
GEGL development is discussed on IRC in #gegl (and sometimes in #gimp) on GIMPnet (irc.gimp.org).
You can subscribe to gegl-developer and view the archives here. The GEGL developer list is the appropriate place to ask development questions, and get more information about GEGL development in general. You can email this list at firstname.lastname@example.org.
