========

QuaggaJS is a barcode-scanner entirely written in JavaScript supporting real-time localization and decoding of 
various types of barcodes such as __EAN__ and __CODE128__. The library is also capable of using `getUserMedia` to get direct 
access to the user's camera stream. Although the code relies on heavy image-processing even recent smartphones are 
capable of locating and decoding barcodes in real-time.

## Yet another barcode library?

This is not yet another port of the great [zxing][zxing_github] library, but more of an extension to it. 
This implementation features a barcode locator which is capable of finding a barcode-like pattern in an 
image resulting in an estimated bounding box including the rotation. Simply speaking, this reader is invariant 
to scale and rotation, whereas other libraries require the barcode to be aligned with the viewport.


## Requirements

In order to take full advantage of quaggaJS, the browser needs to support the `getUserMedia` API which is 
already implemented in recent versions of Firefox, Chrome and Opera. The API is also available on their 
mobile counterparts installed on Android. Safari and IE do not allow the access to the camera yet, neither 
on desktop, nor on mobile. You can check [caniuse][caniuse_getusermedia] for updates.

In cases where real-time decoding is not needed, or the platform does not support `getUserMedia` QuaggaJS is <commit_msg>Added url to the blog post<commit_after>quaggaJS
