Constructor Detail

MultiplyAlphaRed

public MultiplyAlphaRed(CachableRed src,
                        CachableRed alpha)

Multiply the alpha of one image with a mask image. The size of the resultant image is the intersection of the two image bounds. If you want the end image to be the size of one or the other please use the PadRed operator.

Parameters:

src - The image to convert to multiply the alpha of

alpha - The mask image to multiply the alpha channel of src with.
