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

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

This function converts the 4:2:2CbYCr 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.
