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 is NULL. |
