I am developing an application for iPhone retina display and need to be able to desaturate images.
Now, everything I have ever seen says to use the color matrix filter… and this does work on the pc… however, because I am deploying on the iPhone - filters - ALL FILTERS, are not supported… and therefor do nothing.
Is there a way I can turn a color bitmapData into a greyscale image without having to use a colormatrix filter, or any other filter?
