- The basic format is identical -- it's a stream of bits that are on (black)
- or off (white). You must put out enough bytes to fill the entire line --
- there's no 'carriage-return' option.
-
- If you're close to this, you might simply be missing the (previously
- undocumented) prf switch. Try "prf filename -transparent -vers_pp plot"
- and see what you get. By default, stuff is sent to the Versatecs in 'print'
- mode unless one of the filters (for a bitmap, for example) toggles it. If
- you use -transparent, there's no toggle done, and you get that default, giving
- you yards and yards and yards of paper (talk about your 15yard penalty!)
-
- Hope this helps a bit....
