Hi Rana,
Your code mostly looks ok, a few things looked a little odd to me however.
First you declare 'SVGGraphics2D svgGenerator' twice! so I might guess that you stream the first one and not the second.
Also you flush 'fos', but not 'out', you should flush 'out', then flush 'fos' (then close fos). You might also want to look at what it actually outputs - for example it might embed an image which would be written to D: (but it might not be able to find it). For Swing components you might want to use 'SwingSVGPrettyPrint' because it will try to ensure that you don't just get Swing's double buffer.

I am trying to save a jgraph object as an SVG file and I’m having problems with it. I spent so much time on it and so if someone encountered a similar problem or knows a solution, I would greatly appreciate it.
Basically, this method attempts to save the jgraph as SVG. The file is produced, but 1) it’s blank white and 2) there are no scrolling capabilities.
public void saveGraphAsSVG(JGraph graph) {
try {
/* Create file output stream. */
FileOutputStream fos = new FileOutputStream(new
File("D:\\final.svg"));
/* Created writer with UTF-8 encoding. */
Writer out = new OutputStreamWriter(fos, "UTF-8");
/* Get a DOMImplementation. */
DOMImplementation domImpl =
GenericDOMImplementation.getDOMImplementation();
/* Create an instance of Document. */
Document document = domImpl.createDocument(null, "svg", null);
/* Create an instance of the SVG Generator. */
SVGGraphics2D svgGenerator = new SVGGraphics2D(document);
SVGGeneratorContext ctx = SVGGeneratorContext.createDefault(
document);
ImageHandler ihandler = new ImageHandlerPNGEncoder(
"D:\\", null);
ctx.setImageHandler(ihandler);
SVGGraphics2D svgGenerator = new SVGGraphics2D(ctx, false);
svgGenerator.setSVGCanvasSize(new Dimension(2000, 2000));
graph.paint(svgGenerator);
/* Use CSS style attribute. */
boolean useCSS = true;
/* Finally, stream out SVG to the writer. */
svgGenerator.stream(out, useCSS);
/* Close the file output stream. */
fos.flush();
fos.close();
}
catch (IOException e) {
e.printStackTrace();
}
}
}
Thanks,
Rana
