Format tokens as an SVG graphics file. This formatter is still experimental.
Each line of code is a ``<text>`` element with explicit ``x`` and ``y``
coordinates containing ``<tspan>`` elements with the individual token styles.
By default, this formatter outputs a full SVG document including doctype
declaration and the ``<svg>`` root element.
.. versionadded:: 0.9
Additional options accepted:
`nowrap`
Don't wrap the SVG ```` elements in ``
don't add a XML declaration and a doctype. If true, the `fontfamily` and `fontsize` options are ignored. Defaults to ``False``.
`fontfamily`
The value to give the wrapping ``<g>`` element's ``font-family``
attribute, defaults to ``"monospace"``.
`fontsize`
The value to give the wrapping ``<g>`` element's ``font-size``
attribute, defaults to ``"14px"``.
`linenos` If ``True``, add line numbers (default: ``False``).
`linenostart`
The line number for the first line (default: ``1``).
`linenostep` If set to a number n > 1, only every nth line number is printed.
`linenowidth`
Maximum width devoted to line numbers (default: ``3*ystep``, sufficient for up to 4-digit line numbers. Increase width for longer code blocks).
`xoffset`
Starting offset in X direction, defaults to ``0``.
`yoffset`
Starting offset in Y direction, defaults to the font size if it is given in pixels, or ``20`` else. (This is necessary since text coordinates
refer to the text baseline, not the top edge.)
`ystep`
Offset to add to the Y coordinate for each subsequent line. This should
roughly be the text size plus 5. It defaults to that value if the text
size is given in pixels, or ``25`` else.
`spacehack`
Convert spaces in the source to `` ``, which are non-breaking
spaces. SVG provides the ``xml:space`` attribute to control how
whitespace inside tags is handled, in theory, the ``preserve`` value
could be used to keep all whitespace as-is. However, many current SVG
viewers don't obey that rule, so this option is provided as a workaround and defaults to ``True``. """
