This is how I would see something like this added for GEGL operations: The desired end result would be to have a directory where previews of the results of gegl-operations can be found. Probably just pngs with the same name as the op it is a preview for. During the build of operations that come with GEGL a small set of illustrative images would be provided. By default if no extra work is done in the operation the default image will be used as input with default parameters. If this does not provide a good preview of the operation the op can add a string to GeglOperationClass containing the XML needed to apply the effect well to one (or more) of the sample images. These images would also be used in the GEGL documentation http://gegl.org/operations.html -- «The future is already here.
