||ln63wkp@sdcc4.UUCP asks
||Does there exist a graphics converter which will convert Amiga IFF
||(HAM, grey or color) into 1 bitplane black & white pic using 
||Floyd Steinberg dithering instead of ordered dither?   I've only
||seen one program so far that will convert AmyColor->1bit which is
||MacView.  Unfortunately it uses the ordered dither method which 
||doesn't look as nice as FS.

I a related note, does anyone have or know the algorythm (sp?) for the FS
dither?  I have an IFF->XBM program that I wrote that uses a "kinda"
ordered dither, but an FS would probably look much better.  If you
know the general procedure, please mail it to me.  Thanks!
