PCBPSPLT is a filter to read the output from PCBPRINT (microsoft!randyn's
printed circuit board router) and generate PostScript for an apple
laserwriter from that.
PCBPSPLT takes no arguments. To use it, just redirect the output files (one at
a time) from PCBPRINT into PCBPSPLT, and pipe stdout to a PostScript
printer.
PCBPSPLT operates as follows:
1. if a file named "PCBPSPLT.PRO" exists in your current directory,
that file is prepended.
2. The input lines are translated into PostScript format. A crude
attempt is made to center the drawing on the page, based on
the DIMENSION information.
3. If a file named "PCBPSPLT.EPI" exists in your current directory,
that file is appended.
Normally, PCBPSPLT.PRO contains any necessary setup information that you might
need. For example, our UNIX printer spooler needs "%!\n" as the first
line in the file to decide that the file contains PostScript and not
just ascii text. It could be used to adjust scaling, rotation, and
other transformations as well.
Normally, PCBPSPLT.EPI just does a showpage, but it could also add titles,
etc.
The source is fairly simple, and could easily be used to generate other
plotting formats.
Happy plotting! Dave Schmidt, WB7RDI (amc!daves)
