Detailed Description

PHP class to creates array representations for 2D barcodes to be used with TCPDF (http://www.tcpdf.org).

Definition at line 50 of file 2dbarcodes.php.

Constructor & Destructor Documentation

__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

$code

(string) code to print

$type

(string) type 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 parametrs 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.
