OK, I was quite certain I would be misunderstood. I KNOW you can save
your transparent BACKGROUND in .xpm format, but I mean transparent
pixels. For example, if you use a transparent background and draw
transparent pixels on it, you can save it with the .xcf format and get
it back later with the same aspect, shape, transparent pixels, and so
on. But if you save it using the .xpm format, all transparent pixels
wille be, either deleted if too much transparent, or changed to full
opacity. This is a problem for sprites having a good looking over the
background.
But maybe some aspects of the .xpm fornat are unknown to me ?
