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

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 if
pSrc
or
pDst
is
NULL
.
ippStsSizeErr
Indicates an error condition if
roiSize
has a field with a zero or negative value.

Intel's compilers may or may not optimize to the same degree for non-Intel microprocessors for optimizations that are not unique to Intel microprocessors. These optimizations include SSE2, SSE3, and SSSE3 instruction sets and other optimizations. Intel does not guarantee the availability, functionality, or effectiveness of any optimization on microprocessors not manufactured by Intel. Microprocessor-dependent optimizations in this product are intended for use with Intel microprocessors. Certain optimizations not specific to Intel microarchitecture are reserved for Intel microprocessors. Please refer to the applicable product User and Reference Guides for more information regarding the specific instruction sets covered by this notice.
