README

PHP binding for librsvg2. It allows conversion (rasterisation) of SVG image to PNG, with minimal dependencies.

Why

Recommended way to convert SVG in PHP is by using the ImageMagick extension. However, its SVG functionality may be limited depending on your system libraries. The actual conversion process is performed by imagemagick-6.q16, which has optional SVG support. For full SVG support, proper compilation is required, and in the background, it utilizes librsvg2.
There are alternative conversion methods available, but they require cross-process communication.

Installation

sudo apt install librsvg2-2
composer require pavlm/ffi-librsvg

Usage

<?php
use pavlm\Rsvg\Rsvg;

require 'vendor/autoload.php';

$svgData = '<svg viewBox="0 0 100 100">  <rect x="10" y="10" width="80" height="80" fill="green" />  </svg>';

print Rsvg::convertSvg2Png($svgData);
