[comp.lang.postscript] halftone pictures

luoma@BINAH.CC.BRANDEIS.EDU (04/17/91)

 I want to convert a digitized image to a halftone picture.
 I would also like to change the resolution.  Even after
 looking at the POSTSCRIPT LANGUAGE REFERENCE MANUAL
 (the red book?), I am unsure how to convert my image.
 I would appreciate any information that helps me
 to get a reasonable halftone picture.
