HxSinh

Synopsis

HxImageRep HxSinh (HxImageRep img)

Input

HxImageRep img

The image you want to take the hyperbolic sine of.

Return value

HxImageRep

The pixelwise hyperbolic sine of the input image.

Description

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

Remarks

Overflow error

The function HxSinh can result in an overflow error.

Examples

Taking the hyperbolic sine of an image.

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

HxImageRep HxSinhExample1(HxImageRep img) {
   img = HxImageAsDouble(img);
   img = HxContrastStretch(img, 4.0);
   img = HxAddVal(img, -2.0);
   img = HxSinh(img);
   img = HxContrastStretch(img, 255.0);
   img = HxImageAsByte(img);
   return img;
}

int main(int argc, char* argv[])
{
    HxImageRep im1 = HxMakeFromFile(argv[1]);
    im1 = HxSinhExample1(im1);
    HxWriteFile(im1, argv[2]);

    return 0;
}
