- Poor PostScript is probably your problem. If Preview doesn't see the proper
- header and page information in the document it will not display it in color.
- I usually add the following to a trashy PS document to get Preview to display
- it properly.
-
- Add/change the following at the top of the doc.
-
- %!PS-Adobe-2.0
- %%EndComments
- %%BeginProlog
-
- Put the following just before the first page begins.
-
- %%EndProlog
- %%Page: 1 1
-
- Put the following before the rest of the pages (usually after showpage's)
- where x is the proper page number.
-
- %%Page: x x
-
- That is usually enough to make Preview happy.
-
- Note that depending on the consistency of the output, you can probably
- automate these steps in a shell script (I've got one for PATRAN on the Cray).
-
- Hope that helps.
