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 isNULL.
- ippStsSizeErr
- Indicates an error condition ifroiSizehas a field with zero or negative value.
- ippStsStepErr
- Indicates an error condition if any of the specified buffer step values is zero or negative.
