| .SH NAME |
| im_fractsurf \- creates a fractal surface |
| .SH SYNOPSIS |
| .B #include <vips/vips.h> |
| |
| .B int im_fractsurf(in, frdim, size) |
| .br |
| .B IMAGE *in; |

| .B double frdim; |

| .B int size; |
| .SH DESCRIPTION |
| .B 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. |
| .SH RETURN VALUE |
| The function returns 0 on success and -1 on error. |
| .SH SEE\ ALSO |
| im_flt_image_freq(3), im_gausnoise(3) |
