Please note that this module is still in development! Feel free to send me enhancements and ideas :)

Installation

Source installation

In order to build from source, read the relevant instructions first.

On an ubuntu machine perform the following steps to install, node version should be >=4 , tested with versions 4,5,6 (see travis-ci). This is only for installation (npm install) we can then change back to a newer stable node version

$ sudo apt-get install libcairo2-dev libjpeg-dev libgif-dev
$ sudo npm install -g canvas
$ npm install
