I'm using newlisp to make postscript (and thus, PDF) files for cutting things on laser cutters and CNC machines. I love the ability to be precise and exact in my lines and angles.
For CNC cutting, I want to use plywood pieces bigger than a typical sheet of paper. Lots of CNC software accepts PDF files where the page size is 4 feet by 8 feet, the same size as a typical sheet of plywood.
How can I specify page size using the postscript module? If I knew how to edit the raw postscript by hand, I'd submit an updated version of postscript.lsp myself, so if someone knows how to do that in raw postscript, please post here.
