+
+ * 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');
