Hi Joris, you obviously already have the code that paints against a Graphics2D object. You use SVGGraphics2D to produce SVG.
For PNG and PDF you could, of course, use Batik's transcoders to convert the SVG to PNG and PDF: http://xmlgraphics.apache.org/batik/using/transcoder.html But that would be inefficient because it requires two steps. To create a PNG directly, create a BufferedImage and request a Graphics2D from it: Graphics2D g2d = (Graphics2D)bufImage.getGraphics(); // Print to the SVG Graphics2D object graphComponent.getGraphControl().print(g2d); Then use ImageIO to write the BufferedImage to a PNG file. See here for ideas: http://stackoverflow.com/questions/665406/how-to-make-a-color-transparent-in-a-bufferedimage-and-save-as-png For PDF you can try the org.apache.fop.svg.PDFDocumentGraphics2D from Apache FOP. Here's a usage example: http://markmail.org/message/6s6us2hf34h2q3mv PDFDocumentGraphics2D is also used by the PDFTranscoder for Batik to create PDF from SVG.
