AppleScript: Cutting images in the half?

Question

Is it possible to cut an image in the half using AppleScript and save them seperately?

Answer 1

It would be easier to use ImageMagick. This saves the left half as input-0.png and the right half as input-1.png:

convert input.png -crop 50%x100% +repage input.png

This saves just the right half as right.png:

convert input.png -gravity east -crop 50%x100% +repage right.png

+repage removes metadata for the old canvas size. See http://www.imagemagick.org/Usage/crop/.

You can install ImageMagick with brew install imagemagick or sudo port install imagemagick.
