<p>librsvg is a component used within software applications to enable
support for SVG-format scalable graphics. In contrast to raster
formats, scalable vector graphics provide users and artists a way
to create, view, and provide imagery that is not limited to the
pixel or dot density that an output device is capable of.</p>
<p>Many software developers use the librsvg library to render
SVG graphics. It is lightweight and portable.</p>
