YCrCb420ToCbYCr422

Converts 4:2:0 YCrCb image to 4:2:2 CbYCr image.

Syntax

IppStatus ippiYCrCb420ToCbYCr422_8u_P3C2R(const Ipp8u* pSrc[3], int srcStep[3], Ipp8u* pDst, int dstStep, IppiSize roiSize);

Parameters

pSrc

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

srcStep

Array of distances in bytes between starts of consecutive lines in each plane of the source image.

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, height and width should be multiple of 2.

Description

The function ippiYCrCb420ToCbYCr422 is declared in the ippcc.h file. It operates with ROI (see Regions of Interest in Intel IPP).

This function converts the 4:2:0 YCrCb three-plane image pSrc (see Table “Planar Image Formats”) to the 4:2:2 CbYCr two-channel image pDst with the following sequence of samples: Cb0, Y0, Cr0, Y1, Cb1, Y2, Cr1, Y3, Cb2, ... (see Table “Pixel-Order 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 any field of the roiSize is less than 2.
