GEGL has the concept of meta operations: operations implemented in terms of other operations. This maps very nicely to the subgraph concept in FBP/imgflo. It has always been the intention that GEGL could load a serialized description of, but the current GEGL XML format does not support that.

This will require:

  • Upstreaming the .json FBP graph loading code to GEGL (currently in lib/graph.c)
  • Implement construction of a GeglMetaOperation from this format
  • Fix the GEGL module/operation loader to load the .json files found in GEGL_PATH as operations in library

Such operations would then be available for use in applications like GIMP like any other GEGL operation.
