The ForwardDST Method computes the forward Discrete Sine Transform (DST) of the input data.
The ForwardDSTFromImage Method computes the forward Discrete Sine Transform (DST) of the input image. The difference between this method and ForwardDST() is that this method takes an ImGearPage Class as the input. Can be applied only to 8, 16, or 32bit grayscale images with one channel.
