Description
Creates a random affine transform from random transfrom primatives. The default mean and half range of the primatives is 0.0 except for the scale which is 1.0 \(\pm\) 0.0.
Examples
WlzRandomAffineTransform -t -2 -x 1 -X 4.2 -y 1 -Y 8
Creates a 2D translation only transform with random translations of 1.0 \(\pm\) 4.2 (x) and 1.0 \(\pm\) 8.0 (y) which is written to the standard output.
