A while ago, someone posted a program which takes postscript files and optimizes them for output to a postscript device (to speed up output). What we need is a program which optimizes an HPGL file for output to an HP DraftPro pen plotter. We have a CAD package which generates plots without (apparently) optimizing the graphical-data base prior to generating the plot files, so the plotter ends up doing things like: display short line at one end of paper display short line at other end of paper go back to original end and display another line. Needless to say, the pen motion and paper movement commands probably greatly increase the size of the file (and plot). Does anyone have a program which will help me, or does anyone know where I can go to find one? We are not on FTP, so if there is a version of this somewhere on Internet, would someone please mail it to me? We are running VMS 5.0, but also have a UNIX system. I could convert the program from UNIX to VMS if necessary (have C and FORTRAN). Thanks, in advance. Please E-mail me your responses.

I can't help you with a complete program, but there was a very good article in ACM Transactions on Graphics, Vol.2 No.3, July 1983, pages 197-212, titled: "Techniques for Reducing Pen Plotting Time' by David P.Anderson from the University of Wisconsin, Madison. It's a pity but I never got around to implement his stuff into a working program. There is some codefragment in the article. Hope this helps . > Thanks, in advance. Please E-mail me your responses. Please summarie what you learned, as I'm shure others are interested too. fmr@cwi.nl -- It is better never to have been born. But who among us has such luck?
