Introduction to barcode PDF417
The PDF417 is a bi-dimensional barcode allowing to pack a large amount of data in a small space, saving more information than a “traditional” linear barcode. Encoding a full ASCII character set, the barcode PDF417 can contain up to 2,700 characters. A PDF-417 barcode is arranged into columns, guarded by 5 black bars on each side, and each column is split into rows of clusters. Each cluster represents a codeword encoding a value which, taken with all the other values, defines the encoded data. This symbology includes error correction features (Reed Salomon) allowing to repair and read also damaged or incomplete barcodes.

Recogniform Barcode PDF417 Recognition Library
Recogniform PDF417 Recogntion Engine finds all the barcodes automatically anywhere on the image, independent of skew, orientation and flipping. You'll get high recognition accuracy and performance also under poor quality conditions.
