[magick-users] Selection from image

[Fred Weinhaus]

Claus,

I don't think you can use a clone as an output image. It is typically 
used as copies of already created images for use as input to some 
function. There is no such thing as clone2. The syntax is -clone 2 
and would refer to the third image in the command line sequence which 
should already exist.
