-== REQUIREMENTS ==

-

- * PHP5

- * PHP GD2 extension with JPEG and PNG support

- 

-== INSTALLATION ==

-

-If you want to recreate cache by yourself make sure cache directory is

-writable and you have permisions to write into it. Also make sure you are

-able to read files in it if you have cache option enabled

- 

-== CONFIGURATION ==

-

-Feel free to modify config constants in qrconfig.php file. Read about it in

-provided comments and project wiki page (links in README file)

-

-== QUICK START ==

-

-Notice: probably you should'nt use all of this in same script :)

-

-<?phpb

-

-//include only that one, rest required files will be included from it

-include "qrlib.php"

-

-//write code into file, Error corection lecer is lowest, L (one form: L,M,Q,H)

-//each code square will be 4x4 pixels (4x zoom)

-//code will have 2 code squares white boundary around 

-

-QRcode::png('PHP QR Code :)', 'test.png', 'L', 4, 2);

-

-//same as above but outputs file directly into browser (with appr. header etc.)

-//all other settings are default

-//WARNING! it should be FIRST and ONLY output generated by script, otherwise

-//rest of output will land inside PNG binary, breaking it for sure

-QRcode::png('PHP QR Code :)');

-

-//show benchmark

-QRtools::timeBenchmark();

-

-//rebuild cache

-QRtools::buildCache();

-

-//code generated in text mode - as a binary table

-//then displayed out as HTML using Unicode block building chars :)

-$tab = $qr->encode('PHP QR Code :)');

-QRspec::debug($tab, true);

-

-== TCPDF INTEGRATION ==

-

-Inside bindings/tcpdf you will find slightly modified 2dbarcodes.php.

-Instal phpqrcode liblaty inside tcpdf folder, then overwrite (or merge)

-2dbarcodes.php 

-

-Then use similar as example #50 from TCPDF examples:

-

-<?php

-

-$style = array(

-    'border' => true,

-    'padding' => 4,

-    'fgcolor' => array(0,0,0),

-    'bgcolor' => false, //array(255,255,255)

-);

-

-//code name: QR, specify error correction level after semicolon (L,M,Q,H)

-$pdf->write2DBarcode('PHP QR Code :)', 'QR,L', '', '', 30, 30, $style, 'N');

-                  GNU LESSER GENERAL PUBLIC LICENSE

-                       Version 3, 29 June 2007

-

- Copyright (C) 2007 Free Software Foundation, Inc. <http://fsf.org/>

- Everyone is permitted to copy and distribute verbatim copies

- of this license document, but changing it is not allowed.

-

-

-  This version of the GNU Lesser General Public License incorporates

-the terms and conditions of version 3 of the GNU General Public

-License, supplemented by the additional permissions listed below.

-

-  0. Additional Definitions.

-

-  As used herein, "this License" refers to version 3 of the GNU Lesser

-General Public License, and the "GNU GPL" refers to version 3 of the GNU

-General Public License.

-

-  "The Library" refers to a covered work governed by this License,

-other than an Application or a Combined Work as defined below.

-

-  An "Application" is any work that makes use of an interface provided

-by the Library, but which is not otherwise based on the Library.

-Defining a subclass of a class defined by the Library is deemed a mode

-of using an interface provided by the Library.

-

-  A "Combined Work" is a work produced by combining or linking an

-Application with the Library.  The particular version of the Library

-with which the Combined Work was made is also called the "Linked

-Version".

-

-  The "Minimal Corresponding Source" for a Combined Work means the

-Corresponding Source for the Combined Work, excluding any source code

-for portions of the Combined Work that, considered in isolation, are

-based on the Application, and not on the Linked Version.

-

-  The "Corresponding Application Code" for a Combined Work means the

-object code and/or source code for the Application, including any data

-and utility programs needed for reproducing the Combined Work from the

-Application, but excluding the System Libraries of the Combined Work.

-

-  1. Exception to Section 3 of the GNU GPL.

-

-  You may convey a covered work under sections 3 and 4 of this License

-without being bound by section 3 of the GNU GPL.

-

-  2. Conveying Modified Versions.

-

-  If you modify a copy of the Library, and, in your modifications, a

-facility refers to a function or data to be supplied by an Application

-that uses the facility (other than as an argument passed when the

-facility is invoked), then you may convey a copy of the modified

-version:

-

-   a) under this License, provided that you make a good faith effort to

-   ensure that, in the event an Application does not supply the

-   function or data, the facility still operates, and performs

-   whatever part of its purpose remains meaningful, or

-

-   b) under the GNU GPL, with none of the additional permissions of

-   this License applicable to that copy.

-

-  3. Object Code Incorporating Material from Library Header Files.

-

-  The object code form of an Application may incorporate material from

-a header file that is part of the Library.  You may convey such object

-code under terms of your choice, provided that, if the incorporated

-material is not limited to numerical parameters, data structure

-layouts and accessors, or small macros, inline functions and templates

-(ten or fewer lines in length), you do both of the following:

-

-   a) Give prominent notice with each copy of the object code that the

-   Library is used in it and that the Library and its use are

-   covered by this License.

-

-   b) Accompany the object code with a copy of the GNU GPL and this license

-   document.

-

-  4. Combined Works.

-

-  You may convey a Combined Work under terms of your choice that,

-taken together, effectively do not restrict modification of the

-portions of the Library contained in the Combined Work and reverse

-engineering for debugging such modifications, if you also do each of

-the following:

-

-   a) Give prominent notice with each copy of the Combined Work that

-   the Library is used in it and that the Library and its use are

-   covered by this License.

-

-   b) Accompany the Combined Work with a copy of the GNU GPL and this license

-   document.

-

-   c) For a Combined Work that displays copyright notices during

-   execution, include the copyright notice for the Library among

-   these notices, as well as a reference directing the user to the

-   copies of the GNU GPL and this license document.

-

-   d) Do one of the following:

-

-       0) Convey the Minimal Corresponding Source under the terms of this

-       License, and the Corresponding Application Code in a form

-       suitable for, and under terms that permit, the user to

-       recombine or relink the Application with a modified version of

-       the Linked Version to produce a modified Combined Work, in the

-       manner specified by section 6 of the GNU GPL for conveying

-       Corresponding Source.

-

-       1) Use a suitable shared library mechanism for linking with the

-       Library.  A suitable mechanism is one that (a) uses at run time

-       a copy of the Library already present on the user's computer

-       system, and (b) will operate properly with a modified version

-       of the Library that is interface-compatible with the Linked

-       Version.

-

-   e) Provide Installation Information, but only if you would otherwise

-   be required to provide such information under section 6 of the

-   GNU GPL, and only to the extent that such information is

-   necessary to install and execute a modified version of the

-   Combined Work produced by recombining or relinking the

-   Application with a modified version of the Linked Version. (If

-   you use option 4d0, the Installation Information must accompany

-   the Minimal Corresponding Source and Corresponding Application

-   Code. If you use option 4d1, you must provide the Installation

-   Information in the manner specified by section 6 of the GNU GPL

-   for conveying Corresponding Source.)

-

-  5. Combined Libraries.

-

-  You may place library facilities that are a work based on the

-Library side by side in a single library together with other library

-facilities that are not Applications and are not covered by this

-License, and convey such a combined library under terms of your

-choice, if you do both of the following:

-

-   a) Accompany the combined library with a copy of the same work based

-   on the Library, uncombined with any other library facilities,

-   conveyed under the terms of this License.

-

-   b) Give prominent notice with the combined library that part of it

-   is a work based on the Library, and explaining where to find the

-   accompanying uncombined form of the same work.

-

-  6. Revised Versions of the GNU Lesser General Public License.

-

-  The Free Software Foundation may publish revised and/or new versions

-of the GNU Lesser General Public License from time to time. Such new

-versions will be similar in spirit to the present version, but may

-differ in detail to address new problems or concerns.

-

-  Each version is given a distinguishing version number. If the

-Library as you received it specifies that a certain numbered version

-of the GNU Lesser General Public License "or any later version"

-applies to it, you have the option of following the terms and

-conditions either of that published version or of any later version

-published by the Free Software Foundation. If the Library as you

-received it does not specify a version number of the GNU Lesser

-General Public License, you may choose any version of the GNU Lesser

-General Public License ever published by the Free Software Foundation.

-

-  If the Library as you received it specifies that a proxy can decide

-whether future versions of the GNU Lesser General Public License shall

-apply, that proxy's public statement of acceptance of any version is

-permanent authorization for you to choose that version for the

-Library.

-	 * 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.
