        Introduction

        zbar-py is a module (compatible with both Python 2.7 and 3+) that
        provides an interface to the `zbar <http://zbar.sourceforge.net>`__
        bar-code reading library, which can read most barcode formats as well as
        QR codes. Input images must be 2D numpy arrays of type uint8 (i.e. 2D
        greyscale images).
        
        The zbar library itself packaged along with zbar-py (it's built as a
        python extension), so no external dependencies are required. Building
        zbar requires the iconv library to be present, which you almost
        certainly have, except if you're on windows. Then you probably will need
        to download or build the iconv DLL.
        `Here <http://mlocati.github.io/articles/gettext-iconv-windows.html>`__
        are pre-built 32- and 64-bit binaries for same.

        Prerequisites:
        --------------
        
        -  iconv -- c library required for building zbar-py; see above
        -  numpy -- for running zbar-py
        -  pygame -- for examples using a webcam
        
        Simple examples:
        ----------------
        
        More sophisticated examples can be found in 'examples' directory.
        
        -  Scan for barcodes in a 2D numpy array:
        
        .. code:: python
        
            import zbar
            image = read_image_into_numpy_array(...) # whatever function you use to read an image file into a numpy array
            scanner = zbar.Scanner()
            results = scanner.scan(image)
            for result in results:
                print(result.type, result.data, result.quality, result.position)
        
        -  Scan for UPC-A barcodes and perform checksum validity test:
        
        .. code:: python
        
            import zbar
            import zbar.misc
            image = read_image_into_numpy_array(...) # get an image into a numpy array
            scanner = zbar.Scanner()
            results = scanner.scan(image)
            for result in results:
                if result.type == 'UPC-A':
                    print(result.data, zbar.misc.upca_is_valid(result.data.decode('ascii')))
