YUV420ToBGR

Converts a YUV image that has 4:2:0 sampling to the BGR image.

Syntax

IppStatus ippiYUV420ToBGR_8u_P3C3R(const Ipp8u* pSrc[3], int srcStep[3], Ipp8u* pDst, int dstStep, IppiSize roiSize);

Domain Dependencies

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

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

Parameters

pSrc	An array of pointers to ROI in each color plane in the source image.
srcStep	An array of distances in bytes between starts of consecutive lines in 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 source and destination ROI in pixels.

Description

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

This function converts the Y'U'V' image pSrc to the gamma-corrected B'G'R' image pDst according to the same formulas as the function ippiYUVToRGB does. The input data must be presented in the 4:2:0 sampling format (see Table “Planar Image Formats” for more details).

roiSize.width and roiSize.height should be multiples of 2. Otherwise, the function reduces their original values to the nearest multiples of 2, performs operation, and returns warning message.

Return Values

ippStsNoErr	Indicates no error. Any other value indicates an error or a warning.
ippStsNullPtrErr	Indicates an error condition if pSrc or pDst is NULL.
ippStsSizeErr	Indicates an error condition if roiSize has a field with a zero or negative value.
ippStsDoubleSize	Indicates a warning if roiSize has a field that is not a multiple of 2.
