Reference

Methodsnew()
           Create a new bar code image scanner instance.

       get_results()
           Return a list of Barcode::ZBar::Symbol results from the last scanned image.

       scan_image([image])
           Scan  a  Barcode::ZBar::Image  for bar codes.  The image must be in the "Y800" format.  If necessary,
           use "$image->convert("Y800")" to convert from other supported formats to Y800 before scanning.

           Set config for indicated symbology (0 for all) to specified value.

       parse_config(configstr)
           Apply a decoder configuration setting.  See the documentation for "zbarcam"/"zbarimg"  for  available
           configuration options.

       recycle_image([image])
           Remove previously decoded results from a Barcode::ZBar::Image and recycle the associated memory.

Synopsis

           use Barcode::ZBar;

           my $scanner = Barcode::ZBar::ImageScanner->new();
