## PDF.js using SVG
This is a project for implementing alternate backend for PDF.js using Scalable Vector Graphics. This is still a WIP.
Take a look at [proposal](https://docs.google.com/document/d/1k4nPx1RrHbxXi94kSdvW5ay8KMkjwLmBEiCNupyzlwk/pub) for this project.
## Getting started
Take a look at src/display/svg.js to see the SVG rendering code.
