YCbCr422

Converts 4:2:2 YCbCr image.

Syntax

IppStatus ippiYCbCr422_8u_C2P3R(const Ipp8u* pSrc, int srcStep, Ipp8u* pDst[3], int dstStep[3], IppiSize roiSize);

IppStatus ippiYCbCr422_8u_P3C2R(const Ipp8u* pSrc[3], int srcStep[3], Ipp8u* pDst, int dstStep, IppiSize roiSize);

pSrc	Pointer to the ROI in the pixel-order source image. Array of pointers to the ROI in each plane of the planar source image.
srcStep	Distance in bytes between starts of consecutive lines in the source image. Array of distance values for the source image planes.
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 source and destination ROI in pixels.

The function ippiYCbCr422 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 two-channel source image pSrc to the 4:2:2 three-plane image pDst and vice versa (see Table “Pixel-Order Image Formats” and Table “Planar Image Formats” for more details on 4:2:2 planar and pixel-order 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 of the first plane is less than 2, or roiSize.height is less than or equal to zero.
