A script that stitches two images vertically together - very handy for merging screenshots of a webpage.

run with ruby image_stitcher.rb <image1> <image2>.

The two images need to have a vertical section which overlaps. The script scans for the overlap and merges the images so that one seamless image results.

To use the script on macOS by dragging two images onto it, use e.g. Platypus, a bash script is included in this rep.

This script ist tested with ruby 2.2.3. It requires the gem rmagick. rmagick requires ImageMagick, e.g. installed with homebrew.
