YCbCr422ToCbYCr422

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

Syntax

IppStatus ippiYCbCr422ToCbYCr422_8u_C2R(const Ipp8u* pSrc, int srcStep, Ipp8u* pDst, int dstStep, IppiSize roiSize);

IppStatus ippiYCbCr422ToCbYCr422_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 destination image ROI.
dstStep	Distance in bytes between starts of consecutive lines in the destination image.
roiSize	Size of the source and destination ROI in pixels; its width should be multiple of 2.

The functions ippiYCbCr422ToCbYCr422 is declared in the ippcc.h file. It operates with ROI (see Regions of Interest in Intel IPP).

This function converts 4:2:2 YCbCr source image pSrc to the 4:2:2 CbYCr two-channel image pDst that has the following sequence of samples: Cb0, Y0, Cr0, Y1, Cb1, Y2, Cr1, Y3, Cb3, ... (see Table “Pixel-Order Image Formats”). The source image can be either two-channel or three-plane (see Table “Pixel-Order Image Formats” and 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 of the first plane is less than 2, or roiSize.height is less than or equal to zero.
