Not Actively Maintained.

If you wish to continue development on this please fork it to your own repo.

Use the GraphicsMagick (1.3.25) inside Heroku.

Usage

Only tested on heroku-16 stack

Requires heroku-buildpack-apt

Insert these buildpacks before the main buildpack for your application: Make sure the apt buildpack is included before this buildpack.

heroku buildpacks:add --index 1 https://github.com/heroku/heroku-buildpack-apt
heroku buildpacks:add --index 2 https://github.com/mcollina/heroku-buildpack-graphicsmagick.git

Include these at the beginning of your Aptfile

:repo:deb http://http.us.debian.org/debian stretch main

libgraphicsmagick1-dev
libgraphicsmagick++1-dev
libjpeg-turbo
libpng-dev
zlib1g-dev
libjasper-dev
libjasper1

The next time you push your application it should install graphicsmagick before your application buildpack.

Heroku Cedar

Heroku dropped the cedar stack on November 4th, 2015. If you still need to run this buildpack on cedar for whatever reason you can do by referencing an older version of the buildpack:

heroku buildpacks:add --index 1 https://github.com/mcollina/heroku-buildpack-graphicsmagick.git#35f87dd
