snippet using Image::Magick Sharpen() ?

Posts: n/a
I am doing some Scaling() with a call like this:
$ErrMsg = $image->Scale( geometry=>"${cMaxFullimgX}x${cMaxFullimgY}"

and would like to follow up with a little Sharpen, but am having a
hard time guessing what "normal" parameters for the call are. Does
anyone have a little snippet to help explain this? I couldn't find any
example in the Doc


sharpen the image with a gaussian operator of the given radius and
standard deviation (sigma).
