I'm modifying the xloadimage program (comp.sources.x) to be able to 
directly display macpaint images on the X terminal. The macpaint format 
seems to be straight forward.  It does, however, call the 'PackBits' 
function. Packbits seems to do some sort of a run-length encoding, but I 
don't believe that it is completely specified in IM. I've found no TNs 
that describe exactly what it does.

Has anyone come across this little bit of trivia?
