BGRToYCbCr411
Converts a BGR image to the YCbCr planar image that has a 4:1:1 sampling format.

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 ifpSrcorpDstisNULL.
- ippStsSizeErr
- Indicates an error condition ifroiSize.widthis less than 4 orroiSize.heightis less than 1.
