Looking again at the API there is the gegl_parse_xml() routine. There is an example of XML code being used to specify a set of operations to be performed as well as the execution of those operations in the gegl binary file (found in the gegl source tree). > What about error checking? What operations are supported? I haven't tried this recently. I'm not sure what happens if there are errors in the input XML file. You may get either an incomplete GeglNode structure (ie. one not containing all parts of the input XML) or NULL. The API doc doesn't specify which. All GEGL operations can be used in an XML file. > 2. Can I work with the individual pixels of an Image using GEGL?

Øyvind Kolås would be the person who could give you the more definite answer on this. -- Cheers! Kevin. http://www.ve3syb.ca/ |"What are we going to do today, Borg?"
