I'm still a newbie at this so I'm a bit confused.... I realize that drawables include both images and layers and that they are not interchangeable. I'm confused by this error message from a call to gimp-drawable-type in a Script-Fu: Script-Fu Error while executing (script-fu-astro-rescale-for-web 5 '(640)) ERROR: Procedural database executing failed: (gimp_drawable_type 5) Image 5 is an RGB image and I was expecting it to return 0. Does gimp-drawable-type really only work on layers or is this a bug? This is GIMP 1.2.1. roland -- PGP Key ID: 66 BC 3B CD Roland B.
