* - $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)
* @param $code (string) code to print
* @param $type (string) type of barcode: - RAW: raw mode - comma-separad list of array rows
- RAW2: raw mode - array rows are surrounded by square parenthesis.
- QRCODE : QR-CODE Low error correction
- QRCODE,L : QR-CODE Low error correction
- QRCODE,M : QR-CODE Medium error correction
- QRCODE,Q : QR-CODE Better error correction
- QRCODE,H : QR-CODE Best error correction
- 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 parametrs are optional. To use a comma character ',' on text options, replace it with the character 255: "\xff".
