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).
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). |
