Well, it depends on what your procedure specifies as image types when it registers. The documentation says: image_types is a comma separated list of image types, or actually drawable types, that this procedure can deal with. Wildcards are possible here, so you could say "RGB*" instead of "RGB, RGBA" or "*" for all image types. If the procedure doesn't need an image to run, use the empty string. > I can't find a way to create a layer in grey levels (or to > change an existing color one to grey levels). Am I overlooking the > obvious or would that only apply to layer masks? Grayscale layers only exist in grayscale images. If you specify "GRAY" and/or "GRAYA" or "*", then your procedure needs to handle those drawable types.
