Norman,

Many thanks for implementing this. Unfortunately it doesn't work for my purpose. I forgot that I needed access to the DocWriter in order to draw the graph onto the pdf. The element tag may end up being useful for other purposes though.

I extended ITextComponent to create a simple tag to renderer JFreeCharts. Possibly someone will find it useful.

public class PdfGraph extends ITextComponent {

 JFreeChart graph = null;
 Element element = null;
 float height;
 float width;

 /**
 *
 */
 public PdfGraph() {

 }

 public void setValue(JFreeChart graph) {
 this.graph = graph;
 }

 /* (non-Javadoc)
 * @see org.jboss.seam.pdf.ui.ITextComponent#createITextObject(javax.faces.context.FacesContext)
 */
 @Override
 public void createITextObject(FacesContext context) {
 graph = (JFreeChart) valueBinding(context, "value", graph);
 height = (Float) valueBinding(context, "height", height);
 width = (Float) valueBinding(context, "width", width);

 UIDocument doc = (UIDocument)this.findITextParent(this, UIDocument.class);
 DocWriter writer = doc.getWriter();

 if (writer instanceof PdfWriter) {
 try {
 PdfContentByte cb = ((PdfWriter)writer).getDirectContent();
 PdfTemplate tp = cb.createTemplate(width, height);
 Graphics2D g2d = tp.createGraphics(width, height, new DefaultFontMapper());
 Rectangle2D r2d = new Rectangle2D.Double(0, 0, width, height);
 this.graph.draw(g2d, r2d);
 g2d.dispose();
 this.element = new ImgTemplate(tp);
 } catch (Exception x) {
 x.printStackTrace();
 }
 }
 }


 /* (non-Javadoc)
 * @see org.jboss.seam.pdf.ui.ITextComponent#getITextObject()

 @Override
 public Object getITextObject() {
 return element;
 }

 /* (non-Javadoc)
 * @see org.jboss.seam.pdf.ui.ITextComponent#handleAdd(java.lang.Object)
 */
 @Override
 public void handleAdd(Object arg0) {
 throw new RuntimeException("No children allowed");
 }

 /* (non-Javadoc)
 * @see org.jboss.seam.pdf.ui.ITextComponent#removeITextObject()
 */
 @Override
 public void removeITextObject() {
 element = null;
 }

 public float getHeight() {
 return this.height;
 }

 public void setHeight(float height) {
 this.height = height;
 }

 public float getWidth() {
 return this.width;
 }

 public void setWidth(float width) {
 this.width = width;
 }

}
