+== 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');
