Heroku Buildpack: Pngquant

This is a Heroku buildpack for using pngquant in your application.

It is designed to be used with heroku-buildpack-multi to combine it with the appropriate real buildpack for your app.

This is based on http://github.com/jayzes/heroku-buildpack-ffmpeg, which was in turn based on https://github.com/shunjikonishi/heroku-buildpack-ffmpeg

Usage

Add a .buildpacks file to the root of your repo that contains this buildpack URL and your real buildpack URL:

https://github.com/jayzes/heroku-buildpack-pngquant
https://github.com/heroku/heroku-buildpack-ruby

Then create an application using the multi buildpack:

$ heroku create --buildpack https://github.com/ddollar/heroku-buildpack-multi

or configure an existing application:

$ heroku config BUILDPACK_URL=https://github.com/ddollar/heroku-buildpack-multi

You can verify that everything is properly installed by running the following command:

$ heroku run "pngquant -h"
