| coeffs[3] | Transformation coefficient values. | |
| dstStep | Destination buffer step size (width of the buffer in bytes). | |
| pDst | Pointer to a location in a destination buffer. | |
| pSrc | Pointer to a location in a source buffer. | |
| roiSize | Specifies the height and width of an ROI. | |
| srcStep | Source buffer step size (width of the buffer in bytes). |
The C3C1 version of the function steps through an ROI in a source buffer, converts a three-channel color image to a gray scale image and writes the converted data to a destination buffer.
The AC4C1 version of the function steps through an ROI in a source buffer, converts a four-channel color image to a gray scale image and writes the converted data to a destination buffer.
