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 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.

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: 
         src1                       src2                       dst
