libqrencode 2.0.0rc4 (Release Candidates branch)
Image libqrencode is a library for encoding data in a QR Code symbol, a kind of 2D symbology that can be scanned by devices such as a mobile phone with a CCD. License: GNU Lesser General Public License (LGPL) Changes:
The API has been changed. An "-i" option to ignore case distinctions has been added to qrencode and view_qrcode. The "-c" option (case-sensitive mode) of qrencode is now enabled by default and has been improved. An "-8" option has been added to qrencode to encode whole data in 8-bit mode. tests/view_qrcode now accepts various options like qrencode. The code has been cleaned up. The mask evaluation bug has been fixed.Image

barcode::zbar::symbol

ZBar::Symbol(3pm)					User Contributed Perl Documentation					 ZBar::Symbol(3pm)

NAME

       Barcode::ZBar::Symbol - bar code scan result object

SYNOPSIS

	   my @symbols = $image->get_symbols();
	   foreach my $sym (@symbols) {
	       print("decoded: " . $sym->get_type() .
		     ":" . $sym->get_data().
		     "(" . $sym->get_count() . ")");
	   }

DESCRIPTION

       Barcode::ZBar::Symbol objects are constant results returned for each bar code scanned from images or video.  This object wraps the raw
       symbol data with additional information about the decode (symbology, confidence, location, etc)

REFERENCE

   Methods
       get_type()
	   The type of bar code "symbology" from which the data was decoded.

       get_data()
	   The decoded data string.  Note that some symbologies can encode binary data.

       get_quality()
	   Confidence metric.  An unscaled integer value that indicates something (intentionally unspecified) about the reliability of this result
	   relative to another.  Larger values are better than smaller values, where "large" and "small" are application dependent.  Expect this
	   definition to become more specific as the metric is enhanced.

       get_count()
	   Current cache count of the symbol.  This integer value provides inter-scan reliability and redundancy information if enabled at the
	   Barcode::ZBar::ImageScanner.

       get_components()
	   Components of a composite result.  This yields an array of physical component symbols that were combined to form a composite result.

	   o A negative value indicates that this result is still uncertain

	   o A zero value indicates the first occurance of this result with high confidence

	   o A positive value indicates a duplicate scan

   Constants
