# SVG file parsing / rendering library
[![Build Status](https://travis-ci.org/PhenX/php-svg-lib.svg?branch=master)](https://travis-ci.org/PhenX/php-svg-lib)
[![Coverage Status](https://coveralls.io/repos/PhenX/php-svg-lib/badge.svg)](https://coveralls.io/r/PhenX/php-svg-lib)
[![Latest Stable Version](https://poser.pugx.org/phenx/php-svg-lib/v/stable)](https://packagist.org/packages/phenx/php-svg-lib)
[![Total Downloads](https://poser.pugx.org/phenx/php-svg-lib/downloads)](https://packagist.org/packages/phenx/php-svg-lib)
[![Latest Unstable Version](https://poser.pugx.org/phenx/php-svg-lib/v/unstable)](https://packagist.org/packages/phenx/php-svg-lib)
[![License](https://poser.pugx.org/phenx/php-svg-lib/license)](https://packagist.org/packages/phenx/php-svg-lib)
The main purpose of this lib is to rasterize SVG to a surface which can be an image or a PDF for example, through a `\Svg\Surface` PHP interface.
This project was initialized by the need to render SVG documents inside PDF files for the [DomPdf](http://dompdf.github.io) project.
