----------
You can also use an HP-UX command pcltrans if you use a starbase library
call to create a starbase format bitmap file.  The starbase bitmap file
takes about 5 - 15 seconds to create (it contains header, colormap, and
frame buffer data).  Then you can fork a child process that invokes pcltrans
allowing your current program to continue while the work of doing the
error diffusion et. al takes place in the (orphaned) child.
