Class NPPNativeMethods.NPPi.Compare

Compare the pixels of two images and create a binary result image. In case of multi-channel image types, the condition must be fulfilled for all channels, otherwise the comparison is considered false.

The "binary" result image is of type 8u_C1. False is represented by 0, true by NPP_MAX_8U.
