## What is QuaggaJS?
QuaggaJS is a barcode-scanner entirely written in JavaScript supporting real-
time localization and decoding of various types of barcodes such as __EAN__,
__CODE 128__, __CODE 39__, __EAN 8__, __UPC-A__, __UPC-C__, __I2of5__ and
__CODABAR__. 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.

## Requirements
## <a name="browser-support">Browser Support</a>
Quagga makes use of many modern Web-APIs which are not implemented by all
browsers yet. There are two modes in which Quagga operates: 1. analyzing static
images and 2. using a camera to decode the images from a live-stream. The latter
requires the presence of the MediaDevices API. You can track the compatibility
of the used Web-APIs for each mode:
- [Static Images](http://caniuse.com/#feat=webworkers,canvas,typedarrays,bloburls,blobbuilder)
- [Live Stream](http://caniuse.com/#feat=webworkers,canvas,typedarrays,bloburls,blobbuilder,stream)
### Static Images
The following APIs need to be implemented in your browser:
- [webworkers](http://caniuse.com/#feat=webworkers)
- [canvas](http://caniuse.com/#feat=canvas)
- [typedarrays](http://caniuse.com/#feat=typedarrays)
- [bloburls](http://caniuse.com/#feat=bloburls)
- [blobbuilder](http://caniuse.com/#feat=blobbuilder)
### Live Stream
In addition to the APIs mentioned above:
- [MediaDevices](http://caniuse.com/#feat=stream)
__Important:__ Accessing `getUserMedia` requires a secure origin in most
browsers, meaning that `http://` can only be used on `localhost`. All other
hostnames need to be served via `https://`. You can find more information in the
[Chrome M47 WebRTC Release Notes](https://groups.google.com/forum/#!topic/discuss-webrtc/sq5CVmY69sc).
### Feature-detection of getUserMedia
Every browser seems to differently implement the `mediaDevices.getUserMedia`
API. Therefore it's highly recommended to include
[webrtc-adapter](https://github.com/webrtc/adapter) in your project.
Here's how you can test your browser's capabilities:
```javascript
if (navigator.mediaDevices && typeof navigator.mediaDevices.getUserMedia === 'function') {
// safely access `navigator.mediaDevices.getUserMedia`
}
```
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, IE (Edge) and Opera. The API is also available on their mobile
counterparts installed on Android (except IE). Safari does not allow the access
to the camera yet, neither on desktop, nor on mobile. You can check
[caniuse][caniuse_getusermedia] for updates.
The above condition evaluates to:
In cases where real-time decoding is not needed, or the platform does not
support `getUserMedia` QuaggaJS is also capable of decoding image-files using
the File API or other URL sources.

| Edge | `true` |
| Chrome | `true` |
| Firefox | `true` |

The remaining properties `drawBoundingBox`, `showFrequency`, `drawScanline` and

#### <a name="ean_extended">Enabling extended EAN</a>
The default setting for `ean_reader` is not capable of reading extensions such
as [EAN-2](https://en.wikipedia.org/wiki/EAN_2) or
[EAN-5](https://en.wikipedia.org/wiki/EAN_5). In order to activate those
supplements you have to provide them in the configuration as followed:
```javascript
decoder: {
readers: [{
format: "ean_reader",
config: {
supplements: [
'ean_5_reader', 'ean_2_reader'
]
}
}]
}
```
Beware that the order of the `supplements` matters in such that the reader stops
decoding when the first supplement was found. So if you are interested in EAN-2
and EAN-5 extensions, use the order depicted above.
It's important to mention that, if supplements are supplied, regular EAN-13
codes cannot be read any more with the same reader. If you want to read EAN-13
with and without extensions you have to add another `ean_reader` reader to the
configuration.
### locator
The `locator` config is only relevant if the `locate` flag is set to `true`.
It controls the behavior of the localization-process and needs to be adjusted
for each specific use-case. The default settings are simply a combination of
values which worked best during development.
Only two properties are relevant for the use in Quagga (`halfSample` and
`patchSize`) whereas the rest is only needed for development and debugging.
```javascript
{
halfSample: true,
patchSize: "medium", // x-small, small, medium, large, x-large
showCanvas: false,
showPatches: false,
showFoundPatches: false,
showSkeleton: false,
showLabels: false,
showPatchLabels: false,
showRemainingPatchLabels: false,
boxFromPatches: {
showTransformed: false,
showTransformedBox: false,
showBB: false
debug: {
showCanvas: false,
showPatches: false,
showFoundPatches: false,
showSkeleton: false,
showLabels: false,
showPatchLabels: false,
showRemainingPatchLabels: false,
boxFromPatches: {
showTransformed: false,
showTransformedBox: false,
showBB: false
}
}
}
```
The `halfSample` flag tells the locator-process whether it should operate on an
image scaled down (half width/height, quarter pixel-count ) or not. Turning
`halfSample` on reduces the processing-time significantly and also helps
finding a barcode pattern due to implicit smoothing.
It should be turned off in cases where the barcode is really small and the full
resolution is needed to find the position. It's recommended to keep it turned
on and use a higher resolution video-image if needed.
The second property `patchSize` defines the density of the search-grid. The
property accepts strings of the value `x-small`, `small`, `medium`, `large` and
`x-large`. The `patchSize` is proportional to the size of the scanned barcodes.
If you have really large barcodes which can be read close-up, then the use of
`large` or `x-large` is recommended. In cases where the barcode is further away
from the camera lens (lack of auto-focus, or small barcodes) then it's advised
to set the size to `small` or even `x-small`. For the latter it's also
recommended to crank up the resolution in order to find a barcode.

## <a name="tipsandtricks">Tips & Tricks</a>
A growing collection of tips & tricks to improve the various aspects of Quagga.
### Barcodes too small?
Barcodes too far away from the camera, or a lens too close to the object
result in poor recognition rates and Quagga might respond with a lot of
false-positives.
Starting in Chrome 59 you can now make use of `capabilities` and directly
control the zoom of the camera. Head over to the
[web-cam demo](https://serratus.github.io/quaggaJS/examples/live_w_locator.html)
and check out the __Zoom__ feature.
You can read more about those `capabilities` in
[Let's light a torch and explore MediaStreamTrack's capabilities](https://www.oberhofer.co/mediastreamtrack-and-its-capabilities)
### Video too dark?
Dark environments usually result in noisy images and therefore mess with the
recognition logic.
Since Chrome 59 you can turn on/off the __Torch__ of our device and vastly
improve the quality of the images. Head over to the
[web-cam demo](https://serratus.github.io/quaggaJS/examples/live_w_locator.html)
and check out the __Torch__ feature.
