YCrCb420ToYCbCr422

Converts 4:2:0 YCrCb image to 4:2:2 YCbCr image.

Syntax

IppStatus ippiYCrCb420ToYCbCr422_8u_P3R(const Ipp8u* pSrc[3], int srcStep[3], Ipp8u* pDst[3], int dstStep[3], IppiSize roiSize);

IppStatus ippiYCrCb420ToYCbCr422_8u_P3C2R(const Ipp8u* pSrc[3], int srcStep[3], Ipp8u* pDst, int dstStep, IppiSize roiSize);

pSrc	Array of pointers to the ROI in each plane of the source image.
srcStep	Array of distances in bytes between starts of consecutive lines in each plane of the source image.
pDst	Pointer to the ROI in the pixel-order destination image. Array of pointers to the ROI in each plane of the planar destination image.
dstStep	Distance in bytes between starts of consecutive lines in the destination image. Array of distance values for the destination image planes.
roiSize	Size of the ROI in pixels, height and width should be multiple of 2.

The function ippiYCrCb420ToYCbCr422 is declared in the ippcc.h file. This function converts the 4:2:0 YCrCb three-plane image pSrc to the 4:2:2 YCbCr three-plane or two-channel image pDst (see Table “Pixel-Order Image Formats” and Table “Planar Image Formats”).

This function operates with ROI (see Regions of Interest in Intel IPP).

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.
