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.
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
$ docker run --rm -i ezrgif -h
Usage:
ezrgif (roll | wobble | pulse | zoom | shake | woke | fried | optimize) [ -h ] [ OPTIONS ]$ ./gif -h
