Parameters
pSrc, pSrc1, pSrc2 |
Pointers to the source images ROI. |
srcStep, src1Step, src2Step |
Distances in bytes between starts of consecutive lines in the source images. |
pDst |
Pointer to the destination image ROI. |
dstStep |
Distance in bytes between starts of consecutive lines in the destination image. |
pSrcDst |
Pointer to the source and destination image ROI for the in-place operation. |
srcDstStep |
Distance in bytes between starts of consecutive lines in the source and destination image for the in-place operation. |
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 performs a bitwise exclusive OR operation between the values of corresponding pixels of two source image ROIs, and writes the result into a destination image ROI.
Note that the functions with the AC4 descriptor do not process alpha channels.
Return Values
ippStsNoErr |
Indicates no error. Any other value indicates an error or a warning. |
ippStsNullPtrErr |
Indicates an error condition if one of the specified pointers is NULL. |
ippStsSizeErr |
Indicates an error condition if roiSize has a field with zero or negative value. |
ippStsStepErr |
Indicates an error condition if any of the specified buffer step values is zero or negative. |
