yeetgif
Composable GIF effects CLI, with reasonable defaults. Made for custom Slack/Discord emoji :)
Get it
Alternative 1: go get
go get -u github.com/sgreben/yeetgif/cmd/gifAlternative 2: just download the binary
Either from the releases page, or from the shell:
# Linux
curl -L https://github.com/sgreben/yeetgif/releases/download/1.23.6/gif_1.23.6_linux_x86_64.tar.gz | tar xz
# OS X
curl -L https://github.com/sgreben/yeetgif/releases/download/1.23.6/gif_1.23.6_osx_x86_64.tar.gz | tar xz
# Windows
curl -LO https://github.com/sgreben/yeetgif/releases/download/1.23.6/gif_1.23.6_windows_x86_64.zip
unzip gif_1.23.6_windows_x86_64.zipNOTE: To use the optimize command, you'll also need the giflossy fork of gifsicle installed:
brew install giflossyYou'll likely also want to have the binary in your $PATH. You can achieve this by adding this to your .bashrc (or .zshrc, ...):
export PATH=<directory-containing-the-gif-binary>:$PATHAlternative 3: docker
docker pull quay.io/sergey_grebenshchikov/yeetgif
docker tag quay.io/sergey_grebenshchikov/yeetgif gif # (optional)Use it

Conventions & tips
- To find out how a given example was made, try running
gif meta showon it (e.g.<yeet.gif gif meta show -pwill print the shell pipe of gif effects used to createyeet.gif). - Use the
--raw(-r) option for intermediate pipe steps -- this is faster than re-encoding as GIF every time. Also it's lossless. - Options with bracketed default values (e.g.
--noiseoffried) can take comma-separated values - the points will be spread over the animation length, with intermediate values linearly interpolated. - To figure out what a parameter does, try out some values around its default value, as well as much larger/smaller ones.
- To reduce GIF size, try specifying a smaller number of duplicates for static images (e.g.
gif -n 20),gif optimize, and dropping framesgif chop drop every <N>.
