If not, how do I produce a new (rotated) svg from an existing svg?
All I
found on this was how to do it w/ JSVGCanvas, but I need to do this
w/out
starting a gui.
an SVGGraphics2D has the method rotate. Maybe this is helpful and it is
not a GUI, or?

Thanks, this could be what I'm looking for. There is still something I
am missing, though, as I can't get it working. This is what I did (a
little simplified):
String svg = ... // generated internally inside the app
String parser =
XMLResourceDescriptor.getXMLParserClassName() ;
SAXSVGDocumentFactory factory = new SAXSVGDocumentFactory( parser ) ;
Reader svgreader = new StringReader( svg ) ;
Document doc =
factory.createDocument( SVGDOMImplementation.SVG_NAMESPACE_URI, svgreader
) ;
boolean rotateClockwise = ...
double theta = ( rotateClockwise ? -Math.PI : Math.PI ) / 2 ;
SVGGraphics2D graphics = new SVGGraphics2D( doc ) ;
graphics.rotate( theta ) ;
graphics.dispose() ;
But nothing happened, i.e. when I transcoded doc into png, the pic was
not rotated. What might I be missing?
Could it be that SVGGraphics2D is meant for creating svg content
starting from a clean slate, but it is not able to manipulate existing
svg? I.e. does it assume that the Document I pass in the constructor is
empty?
