GEGL

GEGL

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 operations for image loading and storing, color adjustments, and other different forms of image transformation, filtering and compositing. Some software using GEGL is GNU Image Manipulation Program, imgflo, GNOME Photos and iconographer.
