Converts 4:2:2 YCrCb image to 4:1:1 YCbCr image.

pSrc |
Pointer to the source image ROI. |
srcStep |
Distance in bytes between starts of consecutive lines in the source image. |
pDst |
Array of pointers to the ROI in each plane of the destination image. |
dstStep |
Array of distances in bytes between starts of consecutive lines in the destination image planes. |
roiSize |
Size of the ROI in pixels, its width should be multiple of 4. |
This function operates with ROI (see Regions of Interest in Intel IPP).
This function converts the 4:2:2YCrCb two-channel image pSrc (see Table “Pixel-Order Image Formats”) to the 4:1:1YCbCr three-plane image pDst (see Table “Planar Image Formats”).
ippStsNoErr |
Indicates no error. Any other value indicates an error. |
ippStsNullPtrErr |
Indicates an error condition if any of the specified pointers is NULL. |
ippStsSizeErr |
Indicates an error condition if roiSize.width is less than 4. |
