CbYCr422ToYCbCr422

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

Syntax

IppStatus ippiCbYCr422ToYCbCr422_8u_C2R(const Ipp8u* pSrc, int srcStep, Ipp8u* pDst, int dstStep, IppiSize roiSize);

IppStatus ippiCbYCr422ToYCbCr422_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	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, its width should be multiple of 2.

Description

The function ippiCbYCr422ToYCbCr422 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 CbYCr two-channel image pSrc to the 4:2:2 YCbCr two-channel or three-plane image pDst (see Table “Pixel-Order Image Formats” and Table “Planar Image Formats”). The source image has the following sequence of samples: Cb0, Y0, Cr0, Y1, Cb1, Y2, Cr1, Y3, Cb2, ... . Two-channel destination image has different sequence of samples: Y0, Cb0, Y1, Cr0, Y2, Cb1, Y3, Cr1, Y4, ....

Return Values

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.
