Parameters
- pBGR
- Pointer to the source image ROI.
- bgrStep
- Distance in bytes between starts of consecutive lines in the source image.
- pYCC
- Array of pointers to the destination image ROI in each plane.
- yccStep
- 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 24-bit
BGR
image
pBGR
to the
YCoCg
image
pYCC
according to the following formulas:
Y = ((R + 2*G + B)+ 2)/4
Co = ((R - B) + 1))/2
Cg = (( - R + 2*G - B) + 2)/4
Return Values
- ippStsNoErr
- Indicates no error. Any other value indicates an error.
- ippStsNullPtrErr
- Indicates an error condition if one of the specified pointers isNULL.
