docs-rst: automatically convert Graphviz and SVG images
This patch brings scalable figure, image handling and a concept to
embed *render* markups:
* DOT (http://www.graphviz.org)
* SVG
For image handling use the 'image' replacement::
.. kernel-image:: svg_image.svg
:alt: simple SVG image
For figure handling use the 'figure' replacement::
.. kernel-figure:: svg_image.svg
:alt: simple SVG image
SVG image example
Embed *render* markups (or languages) like Graphviz's **DOT** is
provided by the *render* directive.::
.. kernel-render:: DOT
:alt: foobar digraph
:caption: Embedded **DOT** (Graphviz) code.
digraph foo {
"bar" -> "baz";
}
The *render* directive is a concept to integrate *render* markups and
languages, yet supported markups:
* DOT: render embedded Graphviz's **DOT**
* SVG: render embedded Scalable Vector Graphics (**SVG**)
