I would like to use display postscript to preview the contents of a file. AIX 3.1 comes with the program /usr/lpp/DPS/examples/dpsexec that is able to display a postscript file. However, dpsexec cruises past the showpage commands unless you redefine the showpage macro to wait for input from the standard input stream. Also, dpsexec reads instructions from standard input. In order to look at a file, I must hand type the instructions: PS>(/mygroup/myname/showpage.ps) run PS>(/mygroup/myname/mypostscriptfile.ps) run where showpage.ps is a file which redefines the showpage macro and the second line is the postscript file. dpsexec also handles the two xwindows involved in the display process very badly so that I type into the parent window while the image appears in the second, covered window. Uncovering the image window leaves a white void in the image. I have tried with no real success to edit the dpsexec.c program to make it read the filename from the command line and to pause properly at the showpage's. However, I have little knowledge of C and none at all of display postscript. Does anyone have a sensible postscript file previewer program? I imagine a program that is invoked by the line: xpsview mypostscriptfile.ps that opens a large window and presents one page after the next from the contents of mypostscriptfile.ps, while pausing at each showpage. My eternal gratitude to anyone who can do such a thing. Lou Bloomfield Department of Physics University of Virginia LAB3E@VIRGINIA.EDU
