Re: [ferret_users] Contour Labels on White Box?

["William S. Kessler" <william.s.kessler@xxxxxxxx>]

I didn't understand the question (and still I'm not sure I understand  
it even after Ansley's answer).

One solution to many of these dilemmas is to draw whatever you want  
using an otherwise unused color, then do a simple edit of the  
resulting postscript file to modify that particular color. Search the  
mail archives for "edit postscript" and you should find instructions  
to change the colors by modifying the "ct" (color table) code near  
the top of the postscript file. It's pretty easy even if you know  
nothing about postscript code.

Another technique is to define two identical plot boxes (DEFINE  
VIEWPORT). Make your background SHADE or FILL plot, then use the  
second viewport to draw your white contours on top of that.
