Using a very recent ImageMagick (6.6.0), "display" gives me the checkerboard background without the "-immutable" option and a black background with that option when looking at an image with a transparent background. This might be an X server limitation or window manager limitation, but it shows that this feature is not universally available. > (Without that -immutable option, display replaces a transparent > background > with a checkerboard background which apparently is something of an > industry > standard to signal you really do have a transparent background.) I agree that this *can be* a really cool-looking effect, but IMHO it can also be a really annoying/confusing looking effect (depending on what's underneath/behind). I think it would be nice to provide the user the ability to choose how transparent backgrounds are rendered (i.e. either "see-through" to windows underneath/behind or use a predefined opaque background, e.g. checkerboard).
