.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.
