BGRToYCbCr411

Converts a BGR image to the YCbCr planar image that has a 4:1:1 sampling format.

Syntax

IppStatus ippiBGRToYCbCr411_8u_C3P3R(const Ipp8u*
pSrc
, int
srcStep
, Ipp8u*
pDst
[3], int
dstStep
[3], IppiSize
roiSize
);
IppStatus ippiBGRToYCbCr411_8u_AC4P3R(const Ipp8u*
pSrc
, int
srcStep
, Ipp8u*
pDst
[3], int
dstStep
[3], IppiSize
roiSize
);

Parameters
pSrc
Pointer to the source image ROI.
srcStep
Distance in bytes between starts of consecutive lines in the source image.
pDst
An array of pointers to ROI in separate planes of the destination image.
dstStep
An array of distances in bytes between starts of consecutive lines in the destination image planes.
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 a three- or four-channel gamma-corrected B'G'R' image
pSrc
to the planar
Y'Cb'Cr'
image
pDst
according to the same formulas as the function
ippiRGBToYCbCr
does. The difference is that
ippiBGRToYCbCr411
uses the
4:1:1 sampling
format (see Table
“Planar Image Formats”
for more details).
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.width
is less than 4 or
roiSize.height
is less than 1.
