Sorry if this is a rerun, but I don't read this group regularly and didn't see this topic there today... Is anyone aware of an available utility which can convert PostScript (or EPS) to HPGL? If so, please email any info (and I'll post a summary of useful responses if there are any) if you can, post it if you can't. I'm also interested in converting Apollo GMR2D to HPGL.

It would be nice to hear from someone smarter than I (and the other requestors) whether the lack of a response indicates that such a translation is not possible. If there is someone out there knowledgable enough to say yes or no to the possibility of such a conversion, would you please post your opinion. I think it would be appreciated by many.

To convert PostScript to any other image description language you need
a complete PostScript interpreter. I suppose there are PostScript
scanners/parsers already written or you could take a public-domain
PostScript previewer and modify it. It is non-trivial, unlike its
inverse, the conversion of HPGL to PostScript. PostScript is a
full-blown programming language, while HPGL is essentially a series
of pen-movement commands.

Also keep in mind that HP-GL is a vector-oriented language with text and polygon capability, but no raster. (HP-GL/2 adds some raster capability.) SOME PostScript files can be converted to HP-GL, and some cannot. If you are looking at a picture that looks like it could be done on a plotter (i.e., no bitmaps, no grey scales, simple fonts), a conversion is feasible. You'd be much better off trying to convert PostScript to PCL5 (which includes HP-GL/2) for a LaserJet III. There's a much better match of capabilities there.

I seem to recall reading that someone had figured out how to put executable code in HP font cartridges, and that for a measly $600 you could have their PostScript interpreter. BYTE reported that it works very well, but very slow, and I have heard rumors that due to heavy piggy-backing of chips it overheats. -- "Oops." --my dentist, while removing my wisdom teeth Jay Windley - Dept. of Computer & Information Sciences - Kansas State Univ.

It covers fonts, page layouts, development of graphics designs. It contains articles by several good programmers. Stephen F. Roth is the editor, Addison Welsey is the publisher, the ISBN is 0-201-06663-7. It also covers color. Also get the Green book. It is a good book on programming philosophy. Cheers Woody

Postscript can >(just as one example) scale, rotate, translate bit mapped images, and >fonts. It is far far more powerful than HPGL. You don't need to have HPGL do all that, you could do all that in postscript then translate the finished product into HPGL. I will have to check my ventura publisher program, It can read in all sorts of files, postscript, AutoCAD, HPGL and it supports many different printers. I know it supports postscript output, and if it supports HPGL plotters then I would say that it would handle the translation. Just load in a postscript drawing and print it out to a file in HPGL. BTW while on the subject of postscript conversions, does anyone know of a way to convert postscript into a format that can be used in a CAD program? such as DXF, autoCAD files, etc?
