33// DESCRIPTION :
34//
35// Class to create PDF417 barcode arrays for TCPDF class.
36// PDF417 (ISO/IEC 15438:2006) is a 2-dimensional stacked bar code created by Symbol Technologies in 1991.
37// 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.
38// TECHNICAL DATA / FEATURES OF PDF417:
39//		Encodable Character Set:     All 128 ASCII Characters (including extended)
40//		Code Type:                   Continuous, Multi-Row
41//		Symbol Height:               3 - 90 Rows
42//		Symbol Width:                90X - 583X
43//		Bidirectional Decoding:      Yes
44//		Error Correction Characters: 2 - 512
45//		Maximum Data Characters:     1850 text, 2710 digits, 1108 bytes
