``data_uri``
============
.. versionadded:: 2.12
The ``data_uri`` filter was added in Twig 2.12.
The ``data_uri`` filter generates a URL using the data scheme as defined in RFC
2397:
.. code-block:: html+twig
{{ image_data|data_uri }}
{{ source('path_to_image')|data_uri }}
{# force the mime type, disable the guessing of the mime type #}
{{ image_data|data_uri(mime="image/svg") }}
{# also works with plain text #}
{{ '<b>foobar</b>'|data_uri(mime="text/html") }}
{# add some extra parameters #}
{{ '<b>foobar</b>'|data_uri(mime="text/html", parameters={charset: "ascii"}) }}
.. note::
The ``data_uri`` filter is part of the ``HtmlExtension`` which is not
installed by default. Install it first:
.. code-block:: bash
$ composer require twig/html-extra
Then, use the ``twig/extra-bundle`` on Symfony projects or add the extension
explicitly on the Twig environment::
use Twig\Extra\Html\HtmlExtension;
$twig = new \Twig\Environment(...);
$twig->addExtension(new HtmlExtension());
.. note::
The filter does not perform any length validation on purpose (limits depends
on the usage context), validation should be done before calling this filter.
Arguments
---------
* ``mime``: The mime type
* ``parameters``: An array of parameters
