## Overview
The "hello world" example is a minimalistic application of the PDF.js project.
The file `helloworld.pdf` originates from the GNUpdf project and contains a
simple and human-readable PDF.
## Getting started
Instead of simply opening `index.html` in a browser, you must serve the page
using a web server. This can be done on your local machine without an internet
connection. In the root directory of PDF.js, run `node make server` in a
terminal. The example can then be viewed using the following URL:
`http://localhost:8888/examples/helloworld/index.html`
Take a look at `hello.js` to see how to make basic calls to PDF.js.

## 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.
