Split .png into multi-page pdf with imagemagick based on whitespace

Question

Currently I have a hand written image darkened with

convert -level 50x100%

It contains chunks of text separated by whitespace. Simply printing the image would split handwriting in half.

Is there a way to split a png file into a multi-page pdf properly?

Fred's "multicrop" imagemagick-based script might work for you or at least put you in the right direction.
