- I have not been able to display in color a Postscript file that was translated
- from cgm format on a MacIntosh using the Preview utility (release 2.0 v22).
- however, the same file shows colors nicely on a Silicon Graphics computer. This
- is what the beginning of the file looks like:
-
- %!PS
- save
- /w {setlinewidth} def
- /l {lineto} def
- /n {newpath} def
- /m {moveto} def
- /s {scale} def
- /c {setlinecap} def
- /j {setlinejoin} def
- /r {restore} def
- /h {showpage} def
- /t {stroke} def
- /f {eofill} def
- /ct 256 array def
- /o {ct exch get aload pop setrgbcolor} def
- 125 .125 s
- 1 c
- 1 j
- n
- ct 0 [1.000 1.000 1.000] put
- ct 1 [0.000 0.000 0.000] put
- ct 2 [1.000 0.000 0.000] put
-

- Now, I realize that this does not have the recommended file header (the
- Previewer warns that "the file is missing the proper PostScript header
- information. If you attempt to open it anyway, you will only be able to page
- through the file's pages sequentially.) But I haven't had much success with
- modifying the header, as per my next puzzle:
-
- I have files that were generated on a Digital Vax computer, and get the same
- message as above. Here is what the beginning of the Vax generated Postscript
- files look like:
-

- This file does not have any color in it. However, what I would like to do, if
- possible, is to somehow convert this file to be compatible with eps format so
- that I may import it into Framemaker documents. Presently, I make bitmaps into
- tiff files, but this seems clumsy. I have tried a few things like changing the
- file extension from .ps to .eps, and also modifying the comment header to
- conform with what I read in Supplemental documentation: Encapsulated PostScript
- File Specification, Version 2.0, pp. 4-5. That didn't help.

- Suggestions?
