YCrCb420ToYCbCr411

Converts 4:2:0 YCrCb image to 4:1:1 YCbCr image.

Syntax

IppStatus ippiYCrCb420ToYCbCr411_8u_P3P2R(const Ipp8u* pSrc[3], int srcStep[3], Ipp8u* pDstY, int dstYStep, Ipp8u* pDstCbCr, int dstCbCrStep, 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.
pDstY	Pointer to the ROI in the luminance plane of a destination image.
dstYStep	Distance in bytes between starts of consecutive lines in the luminance plane of the destination image.
pDstCbCr	Pointer to the ROI in the interleaved chrominance plane of the destination image.
dstCbCrStep	Distance in bytes between starts of consecutive lines in the interleaved chrominance plane of a destination image.
roiSize	Size of the ROI in pixels, its width should be multiple of 4, its height should be multiple of 2.

Description

The function ippiYCrCb420ToYCbCr411 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 4:1:1 YCbCr two-plane image that contains luminance samples Y0, Y1, Y2, .. in the first plane pDstY, and interleaved chrominance samples Cb0, Cr0, Cb1, Cr1, ... in the second plane pDstCbCr..

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 4 or roiSize.height is less than 2.
