[magick-users] pass minimum width and height to resize?

[Razvan Cosma]

 Hi all,
The docs state that wxh specified in the command line to mogrify or 
through the api are maximum, so an image will fit into, not fill a 
rectangle with a different aspect ratio. I would like to resize to a 
minimum x or y, center then crop the other dimension, filling the space 
available, is this possible? (I'm using perlmagick)
