If this is about the little link diamond that is used in help, then read on. Otherwise this is of little use to you... I looked at the image resource that the shared image is composited from and it is a RGBA image that holds 4bits per sample. Thus, it will be the same whether it displayed on a station or dimension. Chances are that it was dithered when the image was 'cast in stone' as a tiff file. > Robert Kieffer > kieffer@spf.trw.com peter peter@tahiti.umhc.umn.edu
