HxOr

Synopsis

HxImageRep HxOr(HxImageRep im1, HxImageRep im2)

Input

HxImageRep im1

The first input image.

HxImageRep im2

The second input image.

Return value

HxImageRep

The logical `or' of the input images.

Description

The function HxOr takes the logical `or' of corresponding pixels in the two images. The `or' of two vectors is taken component wise.

Remarks

Valid input images

The input images should have the same dimensionality, the same size, the same pixel dimensionality and the same pixel type. The numerical values of the pixels, or its components, should be HxShort, HxByte, HxInt .

Examples

Taking the logical `or'

#include "HxImageRepGlobalFuncs.h"
#include "HxImageRep.h"

HxImageRep HxOrExample1(HxImageRep im1, HxImageRep im2) {
   im1 = HxImageAsDouble(im1);
   im2 = HxImageAsDouble(im2);
   im1 = HxContrastStretch(im1, 1.0);
   im2 = HxContrastStretch(im2, 1.0);
   im1 = HxImageAsByte(im1);
   im2 = HxImageAsByte(im2);
   im1 = HxOr(im1, im2);
   im1 = HxContrastStretch(im1, 255);

   return im1;
}

int main(int argc, char* argv[])
{
    HxImageRep im1 = HxMakeFromFile(argv[1]);
    HxImageRep im2 = HxMakeFromFile(argv[2]);
    im1 = HxOrExample1(im1, im2);
    HxWriteFile(im1, argv[3]);

    return 0;
}
