This is a Heroku buildpack for vendoring the ImageMagick binaries into your project.
In your project root:
heroku buildpacks:add https://github.com/steeple-org/heroku-buildpack-imagemagick --index 1
Now, you may configure ImageMagick by writing some config files in the <your app>/config/magick/*
directory.
Go to https://github.com/steeple-org/imagemagick-bin/ to find
precompiled releases. Edit bin/compile
accordingly, push, and redeploy the app.
