YCbCrToBGR

Converts an YCbCr image to the BGR color model.

Syntax

IppStatus ippiYCbCrToBGR_JPEG_8u_P3C3R(const Ipp8u* pSrc[3], int srcStep, Ipp8u* pDst, int dstStep, IppiSize roiSize);

IppStatus ippiYCbCrToBGR_JPEG_8u_P3C4R(const Ipp8u* pSrc[3], int srcStep, Ipp8u* pDst, int dstStep, IppiSize roiSize);

Parameters

pSrc	Array of pointers to the ROI in each plane of the source image.
srcStep	Distance in bytes between starts of consecutive lines in planes 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.
aval	Constant value to create the fourth channel.

Description

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

This function converts an YCbCr image to the BGR image using the same formulas as the ippiYCbCrToRGB_JPEG function for computing B, G, and R component values.

Return Values

ippStsNoErr	Indicates no error.
ippStsNullPtrErr	Indicates an error condition if any of the specified pointers is NULL.
ippStsSizeErr	Indicates an error condition if roiSize has a field with zero or negative value.
ippStsStepErr	Indicates an error condition if srcStep or dstStep has a zero or negative value.
