babl, a support library for GEGL, provides a generic way to deal with color-space conversions;[4] babl operates abstracting the fundamental color operations so that GEGL need not be aware of them. Through babl, GEGL provides an optimized and powerful (optionally with SIMD support) treatment of arbitrary color data; this enables dependent applications to efficiently support a wide range of color spaces (from 8-bit RGB to full floating point CMYK) with minimal extra application code.
