YUVToRGB

Converts a YUV image to the RGB color model.

Syntax

Case 1: Operation on pixel-order data

IppStatus ippiYUVToRGB_<mod>(const Ipp8u* pSrc, int srcStep, Ipp8u* pDst, int dstStep, IppiSize roiSize);

Supported values for mod:

8u_C3R

8u_AC4R

IppStatus ippiYUVToRGB_8u_C3C4R(const Ipp8u* pSrc, int srcStep, Ipp8u* pDst, int dstStep, IppiSize roiSize, Ippi8u aval);

Case 2: Operation on planar data

IppStatus ippiYUVToRGB_8u_P3R(const Ipp8u* const pSrc[3], int srcStep, Ipp8u* pDst[3], int dstStep, IppiSize roiSize);

Case 3: Conversion from planar to pixel-order data

IppStatus ippiYUVToRGB_8u_P3C3R(const Ipp8u* const pSrc[3], int srcStep, Ipp8u* pDst, int dstStep, IppiSize roiSize);

pSrc	Pointer to the source buffer for pixel-order data. An array of pointers to separate source color planes in case of planar data.
srcStep	Distance in bytes between starts of consecutive lines in the source image.
pDst	Pointer to the destination buffer for pixel-order data. An array of pointers to separate destination color planes in case of planar data.
dstStep	Distance in bytes between starts of consecutive lines in the destination image.
aval	Constant value to create the fourth channel.
roiSize	Size of the source and destination ROI in pixels.

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

This function converts the Y'U'V' image pSrc to the gamma-corrected R'G'B' image pDst according to the following formulas:

R' = Y' + 1.140*V'

G' = Y' - 0.394*U' - 0.581*V'

B' = Y' + 2.032*U'

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.
