NAME
Barcode::ZBar - Perl interface to the ZBar Barcode Reader SYNOPSIS
setup: use Barcode::ZBar; my $reader = Barcode::ZBar::Processor->new(); $reader->init(); $reader->set_data_handler(&my_handler); scan an image: my $image = Barcode::ZBar::Image->new(); $image->set_format('422P'); $image->set_size(114, 80); $image->set_data($raw_bits); $reader->process_image($image); scan from video: $reader->set_visible(); $reader->set_active(); $reader->user_wait(); collect results: my @symbols = $image->get_symbols(); foreach my $sym (@symbols) { print("decoded: " . $sym->get_type() . ":" . $sym->get_data()); } DESCRIPTION
The ZBar Bar Code Reader is a library for scanning and decoding bar codes from various sources such as video streams, image files or raw intensity sensors. It supports EAN, UPC, Code 128, Code 39 and Interleaved 2 of 5. These are the bindings for interacting directly with the library from Perl. REFERENCE
Functions version() Returns the version of the zbar library as "major.minor". increase_verbosity() Increases global library debug by one level. set_verbosity(level) Sets global library debug to the indicated level. Higher numbers give more verbosity. parse_config(configstr) Parse a decoder configuration setting into a list containing the symbology constant, config constant, and value to set. See the documentation for "zbarcam"/"zbarimg" for available configuration options. Constants Width stream "color" constants: SPACE Light area or space between bars. BAR Dark area or colored bar segment. SEE ALSO
