You can render the svg document directly to a java Graphic.
ie.
something like this.
protected void renderSVGDocument(Document doc, int x, int y) {
UserAgent userAgent = new MUserAgent(new AffineTransform());
GVTBuilder builder = new GVTBuilder();
GraphicsNodeRenderContext rc = getRenderContext();
BridgeContext ctx = new BridgeContext(userAgent, rc);
GraphicsNode root;
graphics.translate(x, pageHeight - y);
graphics.setRenderingHints(rc.getRenderingHints());
try {
root = builder.build(ctx, doc);
root.paint(graphics, rc);
} catch (Exception e) {
e.printStackTrace();
}
graphics.translate(-x, y - pageHeight);
}
Where the graphic is where it is being drawn into (after some translation
etc.)
This is how it is done in the AWTRenderer for the FOP project. So if you
want to see the rest of the code look there.
Basically it builds the Root GraphicsNode from the DOM then paints that
into the Graphic.
