Is there a tool/script which can extract images (save them as separate image files) inside an image, each sub-image is separated by whitespace?
Would result in 3x:
My Imagemagick scripts multicrop or multicrop2 will work on your image to separate them into 3 new images. Optionally you can unrotate them. They are Unix bash shell scripts and require a Unix-like environment. See my web site at http://www.fmwconcepts.com/imagemagick/index.php
You do not mention what OS you are using and if you have Imagemagick installed and what version that might be.
