I forgot who originally posted the question, but the person wanted to know
how to decode or unpack Dpaint II pics.  I wrote a program a while back to do that
and display it on the screen or convert it to a screen format file.  As I recall, the
algorithm was fairly simple.  The hardest part may be getting past all of the header
stuff in the Dpaint II picture file (type $C1, I think).  I can provide you with the
algorithm to do all of this stuff I you need it.  BTW, does anyone know whether the
file is packed using the TOOLBOX Pack routine, i.e., can the UNPACK routine be used in
lieu of my algorithm? (at least past the header part.)
