DESCRIPTION

barcodegen will create a barcode image from the given text, a single string is expected as the argument. The barcode image is printed to STDOUT, or written to a file. All barcodes supported by the GD::Barcode Perl module can be handled, for example: Code39 COOP2of5 EAN13 EAN8 IATA2of5 Industrial2of5 ITF Matrix2of5 NW7 QRcode UPCA UPCE. The default barcode type is Code39, and its character set includes the digits 0-9, the letters A-Z (upper case only), and the following symbols: space, minus (-), plus (+), period (.), dollar sign ($), slash (/), and percent (%).

The barcode can be output in any format supported by the Image::Magick perl module. The most common formats include: PNG, JPEG, GIF, EPS, PDF.

Pixel dimensions are used to specify the height and optional border. Resolution of 72 pixels/inch may be assumed when needed - such as in the PostScript output formats.

EXAMPLES

barcodegen ABC123DEF

Will output a PNG image to STDOUT, representing the barcode, with a text label. Default height of 36 pixels, and default border of 10x7.

barcodegen "ABC%123%" --format EPS --height 144 --border 10x7

Will output a Encapsulated PostScript file to STDOUT, with height of 144 pixels, the barcode text label, a border of 10 pixels on left and right sides, and a border of 7 pixels at the top and bottom.

barcodegen 01234567890 --type UPCA --verbose

Will output a PNG image to STDOUT, representing the UPC-A barcode for 01234567890, with a text label that includes the checksum (which is 5 for this barcode). Informational messages will also be printed to STDERR.
