| FwStatus | fwiCbYCr422ToYCbCr420_8u_C2P3R | ( | const Fw8u * pSrc, int srcStep, Fw8u * pDst[3], int dstStep[3], FwiSize roiSize ); |
| dstStep[3] | Destination three-channel planar buffer step size (array values define width of each plane in bytes). | |
| pDst[3] | Pointer to a location in a three-channel planar destination buffer (array values point to a location in each plane). | |
| 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). |
This function steps through an ROI in a source buffer, converts a 2-channel CbYCr color image with 4:2:2 chroma subsampling to a 2-channel YCbCr color image with 4:2:0 chroma subsampling, and writes the converted data to a destination buffer.
