Parameters
- pYCC
- Array of pointers to the source image ROI in each plane.
- yccStep
- Distance in bytes between starts of consecutive lines in the source image.
- pBGR
- Pointer to the destination image ROI.
- bgrStep
- Distance in bytes between starts of consecutive lines in the destination image.
- roiSize
- Size of the source and destination ROI in pixels.
- aval
- Constant value to create the fourth channel.
Description
This function operates with ROI (see
Regions of Interest in Intel IPP
).
This function converts the
YCoCg-R
image
pYCC
to the 24-bit BGR image
pBGR
according to the following formulas:
t = Y - (Cg >> 1)
G = Cg + t
B = t - (Co >> 1)
R = B + Co
The fourth channel is created by setting channel values to the constant value
aval
.
Return Values
- ippStsNoErr
- Indicates no error. Any other value indicates an error.
- ippStsNullPtrErr
- Indicates an error condition if one of the specified pointers isNULL.
