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 Bar code type "symbology" constants: NONE PARTIAL EAN13 EAN8 UPCA UPCE ISBN10 ISBN13 I25 CODE39 CODE128 QRCODE PDF417 SEE ALSO
