NOTE: I have since rewritten this tool in Go as yeetgif. This repo is no longer maintained.
GIF effects from the command-line. (A sh wrapper around imagemagick and the giflossy fork of gifsicle)
Pull & tag:
docker pull quay.io/sergey_grebenshchikov/ezrgif docker tag quay.io/sergey_grebenshchikov/ezrgif ezrgifYou can now simply docker run -i ezrgif.
You can also just get the gif.sh. This probably starts up a bit faster than the Docker option, but you need to take care of the dependencies yourself.
$ curl -sSL https://raw.githubusercontent.com/sgreben/ezrgif/master/gif.sh > gif $ chmod +x gifAs to the dependencies: you will need to install imagemagick, as well as the --lossy fork of gifsicle:
$ brew install imagemagick giflossySee Dockerfile
