convert an HP PaintJet file to a portable pixmap
Reads an HP
PaintJet file as input and converts it into a portable
pixmap. This was a quick hack to save some trees, and it
only handles a small subset of the paintjet commands. In
particular, it will only handle enough commands to convert
most raster image files.
