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')
