Hi-
I think I am missing something Fundemental:
How do I produce color postscript from Object graphics?
I am doing something like this:
sState.myprinter->Draw,sState.oView
sState.myprinter->newdocument
I did a myprinter->GetProperty for color_model, and
it returns 0 (RGB) default. It should then produce PS that
has the same colors as the Screen output right?
I get a nicely shaded grayscale postscript, not color output.
I downloaded David Fanning's xplot.pro, and produced B&W
postscript from that (although it did do Jpeg & gif color)
Any help would be appreciated.
-Terry
