YCrCb422ToYCbCr422

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

Syntax

IppStatus ippiYCrCb422ToYCbCr422_8u_C2P3R(const Ipp8u* pSrc, int srcStep, Ipp8u* pDst[3], int dstStep[3], IppiSize roiSize);

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 2.

The function ippiYCrCb422ToYCbCr422 is declared in the ippcc.h file. It operates with ROI (see Regions of Interest in Intel IPP).

This function converts the 4:2:2 YCrCb two-channel image pSrc (see Table “Pixel-Order Image Formats”) to the 4:2:2 YCbCr three-plane image pDst (see Table “Planar Image Formats”).

ppStsNoErr	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 2.
