Parameters
- pSrc
- Pointer to the source image ROI.
- srcStep
- Distance in bytes between starts of consecutive lines in the source image.
- pDst
- Pointer to the destination image ROI.
- dstStep
- Distance in bytes between starts of consecutive lines in the destination 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 the four-channel gamma-corrected
B'G'R'
image pSrc
to the two-channel Cb'Y'Cr'
image pDst
according to the same formulas as the function ippiRGBToYCbCr
does. The function ippiBGRToCbYCr422
uses 4:2:2 sampling
format for the converted image. An alpha-channel information is lost.An
CbYCr
image has the following sequence of bytes: Cb0Y0Cr0Y1
, Cb1Y2Cr1Y3
, ... . 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.
