30// DESCRIPTION :
31//
32// Class to create PDF417 barcode arrays for TCPDF class.
33// PDF417 (ISO/IEC 15438:2006) is a 2-dimensional stacked bar code created by Symbol Technologies in 1991.
34// It is one of the most popular 2D codes because of its ability to be read with slightly modified handheld laser or linear CCD scanners.
35// TECHNICAL DATA / FEATURES OF PDF417:
36// Encodable Character Set: All 128 ASCII Characters (including extended)
37// Code Type: Continuous, Multi-Row
38// Symbol Height: 3 - 90 Rows
39// Symbol Width: 90X - 583X
40// Bidirectional Decoding: Yes
41// Error Correction Characters: 2 - 512
42// Maximum Data Characters: 1850 text, 2710 digits, 1108 bytes
