+==== Use the helper Class ====
-or at [[https://obel1x.de/dokuwiki/doku.php?id=content:qrcode]] (secure, you know about accepting my certificate)
+If you like to use it from other plugins, you can use the helper- class, like this:
+<file>
+Here are 2 ways to use it (first one gives more control on the result) :
+if (!plugin_isdisabled('qrcode2')) {
+    $qrcode2Helper = plugin_load('helper','qrcode2');
+    // first example
+    $src = $qrcode2Helper->get_img("mailto:johndoe@example.com?subject=promotion", true);
+    print "<img class='qrcode' src='".$src."' alt='*johndoe*' />";
+    // second example
+    $qrcode2Helper->get_img("http://example.com", false, 128);

 === Change Log ===
+  * **2019-12-08**
+    * Enhancement by Simon DELAGE / sdelage@gmail.com New helper-Class added. use it like:
+  * **2018-03-18**
+    * Bugfix by Georg Schmidt / gs-develop@gs-sys.de: when Dokuwiki was installed in Top-Directory of Server, URL will be wrong. This was corrected by extending syntax.php
+<file>
+In my case, it does not work, because the URL to the plugin was wrong.
+"https://<top-level-domain>/dokuwiki/doku.php/lib/plugins/qrcode2/png.php"
+My dokuwiki is using "/doku.php/wiki:tutorial?do=admin&page=config"
+whereas your one is using "/doku.php?id=content:qrcode".
+## The attachment contains a fix.
+## It is not tested with userewrite == 1.
+My solution working (only for userewrite = 2) :
+"https://<top-level-domain>/dokuwiki/doku.php/../lib/plugins/qrcode2/png.php" is effectively
+"https://<top-level-domain>/dokuwiki/lib/plugins/qrcode2/png.php"
+In "syntax.php" change
+    $renderer->doc .= '<img src="lib/plugins/qrcode2/png.php?id='.$data.'" />';
+to
+    $renderer->doc .= '<img src="../lib/plugins/qrcode2/png.php?id='.$data.'" />';
+This is based on https://www.dokuwiki.org/config:userewrite
+I hope, this fix is working on all systems.
+Feel free to contact me for fixing that problem.
