Right now I’m trying to beef up Escher’s PutImage and GetImage implementation. The specification says there are two formats for pixel data transfers. XYPixmap and ZPixmap. However, it is very silent about the actual format of the two. ZPixmap was relatively simple to ‘reverse-engineer’, it is basically a standard pixmap as we all know it. The XYPixmap however is quite different and a real puzzle. I can’t seem to find any documentation on it, and my reverse engineering attempts have not been very sucessful. Does anyone know about this format? Or have a pointer to some documentation? As a last resort, I could fall back to reading the XLib code, but for now I’ll try to get further with my reverse engineering attempts.
