[magick-users] Center image in larger canvas

[Fred Weinhaus]

If all your images are smaller than the size of your desired 
resulting (say 800x800), then the easiest way is to use -extent

see http://www.imagemagick.org/Usage/crop/#extent

You need IM 6.2.4 to use -extent

convert inputimage -background white -extent 800x800 resultimage

you can make the background color whatever you want. see 
http://imagemagick.org/script/color.php
