The program initially creates a gaussian noise image (<a href='im_gausnoise.3.html'>im_gausnoise(3)</a> ) of sizes size x size. The image is then filtered (<a href='im_flt_image_freq.3.html'>im_flt_image_freq(3)</a> ) in order to force the power spectrum to decay according to the desired fractal dimension frdim. The result is a one band float image and should be scaled for display. <h2><a name='sect3' href='#toc3'>Return Value</a></h2> The function returns 0 on success and -1 on error. <h2><a name='sect4' href='#toc4'>See Also</a></h2> <a href='im_flt_image_freq.3.html'>im_flt_image_freq(3)</a> , <a href='im_gausnoise.3.html'>im_gausnoise(3)</a> <h2><a name='sect5' href='#toc5'>Copyright</a></h2> <br> N.
