HxCosh

Synopsis

HxImageRep HxCosh (HxImageRep img)

Input

HxImageRep img

The image you want to take the hyperbolic cosine of.

Return value

HxImageRep

The pixelwise hyperbolic cosine of the input image.

Description

This function takes the hyperbolic cosine of every pixel value of the input image. For vector images, the hyperbolic cosine of every element of the vector is taken.

Remarks

Overflow error

The function HxCosh can result in an overflow error.

Examples

Taking the hyperbolic cosine of an image.

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

HxImageRep HxCoshExample1(HxImageRep img) {
   img = HxImageAsDouble(img);
   img = HxContrastStretch(img, 4.0);
   img = HxAddVal(img, -2.0);
   img = HxCosh(img);
   img = HxContrastStretch(img, 255.0);
   img = HxImageAsByte(img);
   return img;
}

int main(int argc, char* argv[])
{
    HxImageRep im1 = HxMakeFromFile(argv[1]);
    im1 = HxCoshExample1(im1);
    HxWriteFile(im1, argv[2]);

    return 0;
}
