# ZBar Barcode Scanner Plugin
This plugin integrates with the [ZBar](http://zbar.sourceforge.net/) library,
exposing a JavaScript interface for scanning barcodes (QR, 2D, etc).
In this fork a button has been added to turn off and on device flash. In addition the plugin can now handle the device orientation change.
## Installation
cordova plugins install org.cloudsky.cordovaplugins.zbar
## License
This plugin is released under the Apache 2.0 license, but the ZBar library on which it depends (and which is distribute with this plugin) is under the LGPL license (2.1).

drawSight : "true" || "false" //default use true, create a red/green sight to center barcode
