+Contributing
+============
+
+Issue tracker
+-------------
+
+The Issue tracker serves mainly as a place to report bugs and request new features.
+Please do not abuse it as a general questions or troubleshooting location.
+
+General troubleshooting
+-------------
+
+For these questions please use [Discussions](https://github.com/mpdf/mpdf/discussions). Add your enquiry
+to appropriate category and as always, include a reproducible code example when applicable (see code example guidelines below).
+
+You can also use the [mpdf tag](https://stackoverflow.com/questions/tagged/mpdf)
+at [Stack Overflow](https://stackoverflow.com/)
+as the StackOverflow user base is more likely to answer you in a timely manner.
+When doing so, make sure you comply to StackOverflow question guidelines.
+
+Bug reports
+-------------
+
+* Bug reports **MUST** contain a small example in php/html that reproduces the bug.
+* The code example **MUST** be reproducible by copy&paste assuming composer dependencies are installed. That means:
+    * No calling unrelated funcions,
+    * an actual final HTML code has to be present, pasting a template file is not enough,
+    * if the bug considers import or fonts, example source PDF/TTF/etc files have to be included.
+* Failing to provide necessary information or not using the issue template will cause the issue to be closed until required information is provided.
+* Please report one feature or one bug per issue.
+
+Feature requests
+-------------
+
+Feature requests have to be labeled as such and have to include reasoning for the change in question.
+
+
+Pull requests
+-------------
+
+Pull requests should be always based on the default [development](https://github.com/mpdf/mpdf/tree/development)
+branch except for backports to older versions.
+
+Guidelines:
+
+* Use an aptly named feature branch for the Pull request.
+* Only files and lines affecting the scope of the Pull request must be affected.
+* Make small, *atomic* commits that keep the smallest possible related code changes together.
+* Code must be accompanied by a unit test testing expected behaviour whenever possible.
+* To be incorporated, the PR should contain a change in the CHANGELOG.md file describing itself
+
+When updating a PR, do not create a new one, just `git push --force` to your former feature branch, the PR will
+update itself.

+                       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.

+use Mpdf\QrCode\Output;
+
+$qrCode = new QrCode('Lorem ipsum sit dolor');
+
+// Save black on white PNG image 100 px wide to filename.png. Colors are RGB arrays.
+$output = new Output\Png();
+$data = $output->output($qrCode, 100, [255, 255, 255], [0, 0, 0]);
+file_put_contents('filename.png', $data);
+
+// Echo a SVG file, 100 px wide, black on white.
+// Colors can be specified in SVG-compatible formats
+$output = new Output\Svg();
+echo $output->output($qrCode, 100, 'white', 'black');
+
+// Echo an HTML table
+$output = new Output\Html();
+echo $output->output($qrCode);
