Has anyone used RGBImageFilter? I subclassed it and mapped colors from one image to another. The resulting image looks OK within browsers on an NT machine, but the image is "blank" (no image at all and no error messages) on a Mac. I've tried setting the alpha channel by hand and using colors from Netscapes colormap - to no avail. I also tried to run the applet from AppletViewer (JDK 1.0.2) with same result. It seems specific to the Mac. The filter also works fine on an SGI (NS 4.0.2).
Has anyone else run across this? Could it be a problem with a different color model used on the Mac? Does anyone know of an applet that uses the RGBImageFilter?
