Example for converting PDF to PNG using the Node canvas library
2017-03-03 01:48:33 +05:30
## Overview
Example to demonstrate converting a PDF file to a PNG image using the PDF.js library.
## Getting started
Improve the instructions and code for the `pdf2png` example We need to pass `disableFontFace` and `nativeImageDecoderSupport` because Node.js has no native support for `@font-face` and `Image`. Doing so makes it possible to render e.g., the Tracemonkey paper, which failed before. I made this PDF file the default because it's also the default in other examples/demos and because it showcases the possibilities better than the very simple hello world PDF file. Building the library with `gulp dist-install` is easier and is already recommended in the other examples.
