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 inclusive 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.
Example
The code example below
show how to use the function
ippiOr_8u_C1R
.void func_or() { IppiSize Src1ROI = {8,4}; IppiSize Src2ROI = {8,4}; IppiSize DstROI = {5,4}; Ipp8u src1[8*4]; Ipp8u src2[8*4]; Ipp8u dst[8*4]; ippiSet_8u_C1R(0,dest,8,Src1ROI); ippiSet_8u_C1R(5,src1,8,Src1ROI); ippiSet_8u_C1R(6,src2,8,Src2ROI); ippiOr_8u_C1R(src1,8,src2,8,dst,8,DstROI); }
Result:
