  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.

  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
