BGRToYCbCr422
Converts 24-bit per pixel BGR image to 16-bit per pixel YCbCr image.
Syntax
Case 1: Operation on pixel-order data
IppStatus ippiBGRToYCbCr422_8u_C3C2R(const Ipp8u*
pSrc
, int
srcStep
, Ipp8u*
pDst
, int
dstStep
, IppiSize
roiSize
);
IppStatus ippiBGRToYCbCr422_8u_AC4C2R(const Ipp8u*
pSrc
, int
srcStep
, Ipp8u*
pDst
, int
dstStep
, IppiSize
roiSize
);
Case 2: Conversion from pixel-order to planar data
IppStatus ippiBGRToYCbCr422_8u_C3P3R(const Ipp8u*
pSrc
, int
srcStep
, Ipp8u*
pDst
[3], int
dstStep
[3], IppiSize
roiSize
);
IppStatus ippiBGRToYCbCr422_8u_AC4P3R(const Ipp8u*
pSrc
, int
srcStep
, Ipp8u*
pDst
[3], int
dstStep
[3], IppiSize
roiSize
);

Parameters
- pSrc
- Pointer to the source mage ROI.
- srcStep
- Distance in bytes between starts of consecutive lines in the source image.
- pDst
- Pointer to the ROI in the destination pixel-order image. An array of pointers to ROI in each planes of the destination planar image.
- dstStep
- Distance in bytes between starts of consecutive lines in the destination pixel-order image. An array of distances in bytes for each plane of the destination planar image.
- 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 two-channel or three-planes Y'Cb'Cr'
image pDst
according to the same formulas as the function ippiRGBToYCbCr
does. The difference is that ippiBGRToYCbCr422
uses the 4:2:2 sampling
format (see Table “Pixel-Order Image Formats”
and 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 ifpSrcorpDstisNULL.
- ippStsSizeErr
- Indicates an error condition ifroiSize.widthis less than 2 orroiSize.heightis less than 1.
