INSTALL (2042B)

      1 == REQUIREMENTS ==
      2 
      3  * PHP5
      4  * PHP GD2 extension with JPEG and PNG support
      5  
      6 == INSTALLATION ==
      7 
      8 If you want to recreate cache by yourself make sure cache directory is
      9 writable and you have permisions to write into it. Also make sure you are
     10 able to read files in it if you have cache option enabled
     11  
     12 == CONFIGURATION ==
     13 
     14 Feel free to modify config constants in qrconfig.php file. Read about it in
     15 provided comments and project wiki page (links in README file)
     16 
     17 == QUICK START ==
     18 
     19 Notice: probably you should'nt use all of this in same script :)
     20 
     21 <?phpb
     22 
     23 //include only that one, rest required files will be included from it
     24 include "qrlib.php"
     25 
     26 //write code into file, Error corection lecer is lowest, L (one form: L,M,Q,H)
     27 //each code square will be 4x4 pixels (4x zoom)
     28 //code will have 2 code squares white boundary around 
     29 
     30 QRcode::png('PHP QR Code :)', 'test.png', 'L', 4, 2);
     31 
     32 //same as above but outputs file directly into browser (with appr. header etc.)
     33 //all other settings are default
     34 //WARNING! it should be FIRST and ONLY output generated by script, otherwise
     35 //rest of output will land inside PNG binary, breaking it for sure
     36 QRcode::png('PHP QR Code :)');
     37 
     38 //show benchmark
     39 QRtools::timeBenchmark();
     40 
     41 //rebuild cache
     42 QRtools::buildCache();
     43 
     44 //code generated in text mode - as a binary table
     45 //then displayed out as HTML using Unicode block building chars :)
     46 $tab = $qr->encode('PHP QR Code :)');
     47 QRspec::debug($tab, true);
     48 
     49 == TCPDF INTEGRATION ==
     50 
     51 Inside bindings/tcpdf you will find slightly modified 2dbarcodes.php.
     52 Instal phpqrcode liblaty inside tcpdf folder, then overwrite (or merge)
     53 2dbarcodes.php 
     54 
     55 Then use similar as example #50 from TCPDF examples:
     56 
     57 <?php
     58 
     59 $style = array(
     60     'border' => true,
     61     'padding' => 4,
     62     'fgcolor' => array(0,0,0),
     63     'bgcolor' => false, //array(255,255,255)
     64 );
     65 
     66 //code name: QR, specify error correction level after semicolon (L,M,Q,H)
     67 $pdf->write2DBarcode('PHP QR Code :)', 'QR,L', '', '', 30, 30, $style, 'N');
