YCrCb422ToYCbCr422

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

Syntax

IppStatus ippiYCrCb422ToYCbCr422_8u_C2P3R(const Ipp8u* pSrc, int srcStep, Ipp8u* pDst[3], int dstStep[3], IppiSize roiSize);

Domain Dependencies

Headers: ippcore.h, ippvm.h, ipps.h, ippi.h

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

Parameters

pSrc

Pointer to the source image ROI.

srcStep

Distance in bytes between starts of consecutive lines in the source image.

pDst

Array of pointers to the ROI in each plane of the destination image.

dstStep

Array of distances in bytes between starts of consecutive lines in 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 4:2:2YCrCb two-channel image pSrc (see Table “Pixel-Order Image Formats”) to the 4:2:2YCbCr three-plane image pDst (see Table “Planar Image Formats”).

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.
