wkhtmltopdf Buildpack

This is a Heroku buildpack for bundling a compatible wkhtmltopdf binary with your environment.

Versions

• Buildpack: 0.2
• wkhtmltopdf: 0.12.5 by default

NOTE: This fork of the buildpack is designed for a forked version of wkhtmltopdf which renders the header as a background. The binary for this is pulled from this repo. In hindsight this could be improved and will likly change to pull the binary from the forked wkhtmltopdf.

Usage

Add this buildpack to your Heroku application to install the wkhtmltopdf and wkhtmltoimage binaries, and the corresponding library libwkhtmltox, into the dynos:

$ heroku buildpacks:add https://github.com/srbartlett/wkhtmltopdf-buildpack.git

If you want to use a wkhtmltopdf version other than 0.12.3, set WKHTMLTOPDF_VERSION:

heroku config:set WKHTMLTOPDF_VERSION="0.12/0.12.5/wkhtmltox_0.12.5-1.bionic_amd64.deb"

Clearing Repo Cache

Remember to clean your repository cache if you are updating the version of buildpack. To do that, run:
