Perl library to generate CODE 128 bar codes
Barcode::Code128 generates bar codes using the CODE 128 symbology. It can generate images in PNG or GIF format using the GD package, or it can generate a text string representing the barcode that you can render using some other technology if desired.
The intended use of this module is to create a web page with a bar code on it, which can then be printed out and faxed or mailed to someone who will scan the bar code. The application which spurred its creation was an expense report tool, where the employee submitting the report would print out the web page and staple the receipts to it, and the Accounts Payable clerk would scan the bar code to indicate that the receipts were received.
The default settings for this module produce a large image that can safely be FAXed several times and still scanned easily. If this requirement is not important you can generate smaller image using optional parameters, described below.
