YCrCb422ToYCbCr420
Converts 4:2:2 YCrCb image to 4:2:0 YCbCr image.
Syntax
IppStatus ippiYCrCb422ToYCbCr420_8u_C2P3R(const Ipp8u* pSrc, int srcStep, Ipp8u* pDst[3], int dstStep[3], IppiSize roiSize);

Parameters
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, height and width should be multiple of 2. |
Description
This function operates with ROI (see Regions of Interest in Intel IPP).
This functions converts the 4:2:2YCrCb two-channel image pSrc (see Table “Pixel-Order Image Formats”) to the 4:2:0YCbCr three-plane image pDst (see Table “Planar Image Formats”).
Return Values
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 any field of the roiSize is less than 2. |
