NAME
im_fractsurf - creates a fractal surface
 
SYNOPSIS
#include <vips/vips.h>
int im_fractsurf(in, frdim, size)
IMAGE *in;
double frdim;
int size;
 
DESCRIPTION
im_fractsurf
creates a fracta surface.  The program initially creates a gaussian
noise image (im_gausnoise(3)) of sizes size x size.  The image is then
filtered (im_flt_image_freq(3)) 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.
 
RETURN VALUE
The function returns 0 on success and -1 on error.
