HxSin

Synopsis

HxImageRep HxSin (HxImageRep img)

Input

HxImageRep img

The image you want to take the sine of.

Return value

HxImageRep

The pixelwise sine of the input image.

Description

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

Remarks

No possible errors

This function can not result in any errors.

Examples

Taking the sine of an image.

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

HxImageRep HxSinExample1() {
   HxSizes sizes(256, 256, 0);
   double data[256*256];
   for(int i=0; i<256; i++)
        for(int j=0; j<256; j++) {
                data[i+j*256]=(i/32.0)*(i/32.0);
   }
   HxImageRep img = HxMakeFromDoubleData(1, 2, sizes, data);
   img = HxSin(img);
   img = HxContrastStretch(img, 255.0);
   img = HxImageAsByte(img);

   return img;
}

int main(int argc, char* argv[])
{
    HxImageRep img = HxSinExample1();
    HxWriteFile(img, argv[1]);

    return 0;
}

Output image of the HxSin example.

This example generates an images with a number of stripes, using the sine function.
