Or

Performs bitwise inclusive OR operation between pixels of two source buffers.

Syntax

Case 1: Not-in-place operation

IppStatus ippiOr_<mod>(const Ipp<datatype>* pSrc1, int src1Step, const Ipp<datatype>* pSrc2, int src2Step, Ipp<datatype>* pDst, int dstStep, IppiSize roiSize);

Supported values for mod:

8u_C1R	16u_C1R	32s_C1R
8u_C3R	16u_C3R	32s_C3R
8u_C4R	16u_C4R	32s_C4R
8u_AC4R	16u_AC4R	32s_AC4R

Case 2: In-place operation

IppStatus ippiOr_<mod>(const Ipp<datatype>* pSrc, int srcStep, Ipp<datatype>* pSrcDst, int srcDstStep, IppiSize roiSize);

Supported values for mod:

8u_C1IR	16u_C1IR	32s_C1IR
8u_C3IR	16u_C3IR	32s_C3IR
8u_C4IR	16u_C4IR	32s_C4IR
8u_AC4IR	16u_AC4IR	32s_AC4IR

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

The function ippiOr is declared in the ippi.h file. It 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.

Example “Using the Function ippiOr” show how to use the function ippiOr_8u_C1R.

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.

Using the Function ippiOr.

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 05 05 05 05 05 05 05 05 06 06 06 06 06 06 06 06 07 07 07 07 07 00 00 00 05 05 05 05 05 05 05 05 06 06 06 06 06 06 06 06 07 07 07 07 07 00 00 00 05 05 05 05 05 05 05 05 06 06 06 06 06 06 06 06 07 07 07 07 07 00 00 00 05 05 05 05 05 05 05 05 06 06 06 06 06 06 06 06 07 07 07 07 07 00 00 00
