+ <transparent-page-background>true</transparent-page-background>
+ <fonts><!-- described elsewhere --></fonts>
+</renderer>]]></source>

+ The default value for the "transparent-page-background" setting is "false" which
+ paints an opaque, white background for the whole image. If you set this to true,
+ no such background will be painted and you will get a transparent image if
+ an alpha channel is available in the output format.
