Detailed Description

The channel extract primitives copy a single color channel from a multi-channel source image to singl-channel destination image.

The channel is selected by adjusting the source image pointer to point to the desired color channel (see Channel-of-Interest API).

Common parameters for nppiCopy_CXC1 functions include:

Parameters
pSrc Select-Channel Source-Image Pointer.
nSrcStep Source-Image Line Step.
pDst Destination-Image Pointer.
nDstStep Destination-Image Line Step.
oSizeROI Region-of-Interest (ROI).
nppStreamCtx Application Managed Stream Context.
Returns
Image Data Related Error Codes, ROI Related Error Codes
