Well using -repage BEFORE reading an image is not a good idea.
To set the virtual canvas of an image being read in use -page
instead -repage is to change an image already in memory.
Are you sure you want -repage, and nor -resize, or better still
-thumbnail? In any case those are also done AFTER reading in an image.
For examples of thumbnails with shadows see IM Examples, thumbnails
http://www.imagemagick.org/Usage/thumbnails.
Also what format is the output image. JPEG and GIF is bad for soft
shadows. unless the last -background setting is an actual color!
