Huh!? Could you just show us the part of the code you are using to produce your PostScript file. :-) When I Plot, Findgen(10000) I get the same kind of output on the display and in the PostScript file, using either vector fonts or hardware fonts (font=0). Are you using some particular kind of font? Cheers, David -- David W. Fanning, Ph.D. Fanning Software Consulting, Inc.

PSON sets up the PostScript page with the same aspect ratio as the current graphics window, and sizes the plot to fit inside the drawable area of the page. A range of pages sizes (Letter, Legal, A4, etc.) are selectable. For example: ;- Create a plot in a graphics window window, /free plot, indgen(10) * 10000.0 ;- Reproduce the plot in PostScript landscape mode on A4 paper pson, /landscape, paper='A4', filename='test.ps' plot, indgen(10) * 10000.0 psoff The plot in the PostScript file will have the same aspect ratio as it does in the graphics window. I find these utilities much easier to use than the usual SET_PLOT and DEVICE commands. You can find PSON and PSOFF in my example program library at http://www.gumley.com/PIP/About_Book.html Cheers, Liam. Practical IDL Programming http://www.gumley.com/

I use 'em a lot and they're great for quick and easy PS output. In a lot of cases I just want to change the size of a plot so it looks better on a printed page. With PSON/OFF all I do is change the onscreen graphics window to how I want the plot to look/be-sized, invoke PSON, replot, PSOFF, and it's done. No more stuffing around with SET_PLOT and DEVICE. paulv -- Paul van Delst CIMSS @ NOAA/NCEP/EMC Ph: (301)763-8000 x7274 Fax:(301)763-8545
