Dear MathGroup, I would like to make 2D curved regions with color shading across the region. I know one way to do this: make a dense array of points and their associated colors and display them. I would like to be able to use Raster or RasterArray but it always gives a rectangular region which cannot be transformed or mapped to a curved region. What is needed is a "color" that corresponds to transparent. Then a RasterArray could be masked with transparent regions to produce curved shaded regions. By transparent I mean that the underlying graphics will be unaffected and show through. Any suggestions? David Park djmp at earthlink.net http://home.earthlink.net/~djmp/
