The PolyShade command actually creates an image. While
this image is 450 by 650 on your display it can be at
least a factor of 25 or so bigger than that in the PostScript
device, since the pixel size is a least 25 times smaller.

Simply execute the PolyShade command before you Set_Plot
to PostScript and scale the image with the usual XSize
and YSize keywords to the TV command.

Cheers,

David
