Yes, but can I use this for images in the buffer and, in particular, in the display margin? The elisp manual says : Here is a list of other properties that are meaningful for all image types:... :algorithm ALGORITHM' The `:algorithm' property, if non-`nil', specifies a conversion algorithm that should be applied to the image before it is displayed; the value, ALGORITHM, specifies which algorithm. Currently, the only meaningful value for ALGORITHM (aside from `nil') is `laplace'; this applies the Laplace edge detection algorithm, which blurs out small differences in color while highlighting larger differences. People sometimes consider this useful for displaying the image for a "disabled" button. but I can't get this descriptor to do anything. (The images on the toolbar buttons work through the descriptor `:enable') Nick (Miles - sorry about extra copies, I'm still learning to cc to mailing list!)
