<p>
Librsvg's API is divided into two main parts: one for loading SVG
data and one for rendering it. In the <span class="emphasis"><em>loading
stage</em></span>, you create an RsvgHandle object from SVG data,
which can come from a file or from a stream of bytes. In the
<span class="emphasis"><em>rendering stage</em></span>, you take an RsvgHandle and ask
it to render itself to a Cairo context.
</p>
<p><b>Loading. </b>
RsvgHandle is an object that represents SVG data in memory.
Your program creates an RsvgHandle from an SVG file, or from a
memory buffer that contains SVG data, or in the most general
form, from a GIO stream that will provide SVG data. At this
stage you can get either I/O errors or parsing errors. If
loading completes successfully, the RsvgHandle will be ready for
rendering.
</p>
<p><b>Rendering. </b>
Once you have an SVG image loaded into an RsvgHandle, you can
render it to a Cairo context any number of times, or to
different Cairo contexts, as needed. As a convenience, you can
pick a single element in the SVG by its "id" attribute and
render only that element; this is so that sub-elements can be
extracted conveniently out of a larger SVG.
