YCbCr422ToYCrCb422

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

Syntax

IppStatus ippiYCbCr422ToYCrCb422_8u_C2R(const Ipp8u* pSrc, int srcStep, Ipp8u* pDst, int dstStep, IppiSize roiSize);

IppStatus ippiYCbCr422ToYCrCb422_8u_P3C2R(const Ipp8u* pSrc[3], int srcStep[3], Ipp8u* pDst, int dstStep, IppiSize roiSize);

Libraries: ippcore.lib, ippvm.lib, ipps.lib, ippi.lib

Parameters

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 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 4:2:2YCbCr source image pSrc to the 4:2:2 YCrCb two-channel image pDst that has the following sequence of samples: Y0, Cr0, Y1, Cb0, Y2, Cr1, Y3, Cb1, ... (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”).

Return Values

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 is less than 2.
