Constructor & Destructor Documentation

◆ __construct()

TCPDF2DBarcode::__construct ( $code,
$type )

This is the class constructor.

Return an array representations for 2D barcodes:

  • $arrcode['code'] code to be printed on text label
  • $arrcode['num_rows'] required number of rows
  • $arrcode['num_cols'] required number of columns
  • $arrcode['bcode'][$r][$c] value of the cell is $r row and $c column (0 = transparent, 1 = black)
Parameters
string$codecode to print
string$typetype of barcode:
  • DATAMATRIX : Datamatrix (ISO/IEC 16022)
  • PDF417 : PDF417 (ISO/IEC 15438:2006)
  • PDF417,a,e,t,s,f,o0,o1,o2,o3,o4,o5,o6 : PDF417 with parameters: a = aspect ratio (width/height); e = error correction level (0-8); t = total number of macro segments; s = macro segment index (0-99998); f = file ID; o0 = File Name (text); o1 = Segment Count (numeric); o2 = Time Stamp (numeric); o3 = Sender (text); o4 = Addressee (text); o5 = File Size (numeric); o6 = Checksum (numeric). NOTES: Parameters t, s and f are required for a Macro Control Block, all other parameters are optional. To use a comma character ',' on text options, replace it with the character 255: "::xff".
  • QRCODE : QRcode Low error correction
  • QRCODE,L : QRcode Low error correction
  • QRCODE,M : QRcode Medium error correction
  • QRCODE,Q : QRcode Better error correction
  • QRCODE,H : QR-CODE Best error correction
  • RAW: raw mode - comma-separad list of array rows
  • RAW2: raw mode - array rows are surrounded by square parenthesis.
  • TEST : Test matrix
