Conversion Tools: BarCode


CueAct is a utility that uses the CueCat driver to look up information about barcodes swiped by a CueCat read, but also perform any other action of interest associated with the barcodes. CueAct is fully configurable, and comes with a sample configuration file to track Fedex, UPS, and DHL packages, look up books by ISBN numbers, look up UPC barcodes found on commercial items, and EAN- 13 and EAN-13+5 barcodes found on European commercial items. CueAct also comes with the DCdb utility that allows it to look up DigitalConvergence's own "cue" barcodes (found in the US RadioShack catalog for example). A utility called "upce2upca" that expands UPC-E barcodes into UPC-A format was added, so that CueAct can use UPC-E barcodes with programs or Websites that only understand UPC-A.

pdf417_encode converts ASCII strings into pdf417 barcode. This is a two-dimensional barcode that includes error correction up to level 8. The input file will support text that can be specified for byte compaction (hex string), text compaction (ASCII string), and numerical compaction (decimal string). Output formats supported are Postscript and pbm. Reed/Solomon decoding was added to check that ecc is generated correctly.

Pdf417decode [archived link] can decode PDF417 barcode information from a pbm file. The decoder is rather simple, and ignores error correction info. PDF417, or Portable Data File 417, is a two-dimensional stacked bar code symbology capable of encoding over a kilobyte of data per label.
