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

IppStatus ippiYUVToRGB_8u_C3C4R(const Ipp8u*
pSrc
, int
srcStep
, Ipp8u*

);
Case 2: Operation on planar data
IppStatus ippiYUVToRGB_8u_P3R(const Ipp8u*
pSrc
[3], int
srcStep

Parameters
- 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.
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
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'
Return Values
- ippStsNoErr
- Indicates no error. Any other value indicates an error or a warning.
- ippStsNullPtrErr
- Indicates an error condition ifpSrcorpDstisNULL.
- ippStsSizeErr
- Indicates an error condition ifroiSizehas a field with a zero or negative value.
