From wikipedia: In computing, diff is a file comparison utility that outputs the differences between two files.
We have been playing with git. There's more coming! For now, this quick prototype (30M) illustrates some ideas about diff, and images files. It will hopefully be improved in the future :)
In the context of a configuration file, we are combining git's flexibility regarding the choice of a difftool with the image compare features of Imagemagick:
[difftool "mydifftool"] cmd = composite $LOCAL $REMOTE -compose difference x:
It's a digest of two stackoverflow threads:
Are there revision control systems for
images?
How do I view 'git diff' output with visual diff
program?
It's all lo-fi.
