Method Detail

alphaForSourceImageDestinationImage

float alphaForSourceImageDestinationImage(MPSImage sourceImage,
                                          MPSImage destinationImage)

Returns the desired alpha scaling value.

Parameters:

sourceImage - One of the source images in the batch given as a reference for the alpha computation.

destinationImage - One of the destination images in the batch given as a reference for the alpha computation.

Returns:

The desired alpha value.
