Re: Produce Gif via ncargraphic

Peizhong, There is yet another way to obtain a gif file from
PostScript file generated from an NCAR CGM file.
Most PostScript files generated with ctrans yield a vector
PostScript file which can produce very high-resolution color
output on a color printer.

Ghostscript Version 3.1.2 can take an NCAR PS file and convert it
an image file, such as GIF, PBM, TIFF, etc.

The software can be obtained from an MIT anonymous ftp site.
