Class Details



[line 308]

Class to create QR-code arrays for TCPDF class.

QR Code symbol is a 2D barcode that can be scanned by handy terminals such as a mobile phone with CCD.  The capacity of QR Code is up to 7000 digits or 4000 characters, and has high robustness.  This class supports QR Code model 2, described in JIS (Japanese Industrial Standards) X0510:2004 or ISO/IEC 18004.  Currently the following features are not supported: ECI and FNC1 mode, Micro QR Code, QR Code model 1, Structured mode.
This class is derived from "PHP QR Code encoder" by Dominik Dzienia (http://phpqrcode.sourceforge.net/) based on "libqrencode C library 3.1.1." by Kentaro Fukuchi (http://megaui.net/fukuchi/works/qrencode/index.en.html), contains Reed-Solomon code written by Phil Karn, KA9Q. QR Code is registered trademark of DENSO WAVE INCORPORATED (http://www.denso-wave.com/qrcode/index-e.html).
