+# python-zxing
+
+A quick and dirty wrapper for the [ZXing barcode library](https://github.com/zxing/zxing).
+
+This is a hack subprocess control library that gives you a reasonable Python interface to the ZXing command line.  ZXing will recognize and decode 1D and 2D barcodes in images, and return position information and decoded values.  This will let you read barcodes from any images in Python.
+
+If you need to threshold or filter your image prior to sending to ZXing, I recommend using functions from [SimpleCV](http://simplecv.org).
+
+## Usage
+
+```
+git clone https://github.com/zxing/zxing.git
+cd zxing-master
+git clone git://github.com/oostendo/python-zxing.git
+mvn install
+cd core
+wget http://central.maven.org/maven2/com/google/zxing/core/2.2/core-2.2.jar
+mv core-2.2.jar core.jar # Rename
+mvn install
+cd zxing-master/javase
+wget http://central.maven.org/maven2/com/google/zxing/javase/2.2/javase-2.2.jar 
+mv javase-2.2.jar javase.jar # Rename
+mvn install
+```
+
+The library consists of two classes, BarCodeReader and BarCode.  BarCode parses
+the output from ZXing's CommandLineRunner into a BarCode object which includes:
+
+```
+b = zxing.BarCode("""
+file:default.png (format: FAKE_DATA, type: TEXT):
+Raw result:
+foo-bar|the bar of foo
+Parsed result:
+foo-bar 
+the bar of foo
+Also, there were 4 result points:
+  Point 0: (24.0,18.0)
+  Point 1: (21.0,196.0)
+  Point 2: (201.0,198.0)
+  Point 3: (205.23952,21.0)
+""")
+
+print b.format #FAKE_DATA
+print b.raw #foo-bar|the bar of foo
+print b.data #foo-bar\nthe bar of foo
+print b.points #[(24.0, 18.0) ... ]
+```
+
+Initializing the barcode reader, you have to tell it where to find the ZXing core modules.  It is the single parameter, which defaults to the parent directory.
+
+```
+reader = zxing.BarCodeReader("/var/opt/zxing")
+
+barcode = reader.decode("/tmp/image.jpg")
+(barcode1, barcode2) = reader.decode(["/tmp/1.png", "/tmp/2.png"])
+code_list = reader.decode("/tmp/barcodes", True)
+```
+
+decode() takes an image path, directory, or list of images and has an optional parameter to use the "try_harder" option.  If no barcode is found, it returns None objects. 
+
+Installation is manual.
