Saving Rendered HTML in JTextPane as TIFF

Question

Can someone help me in getting started with some sample code that does the following?
I would like to save the WYSIWYG Image of the HTML and graphics displayed by specifying a URL in a JTextPane or JEditorPane. I would like to save the resulting image as a TIFF.
If anyone has any sample code that does this, I would appreciate it if you can share this or help me in getting started.
Thanks

Hi,
This problem can be reduced to the problem of saving the contents of any panel that derives from a JPanel or Canvas.
See my webpage on:
http://www.ida.liu.se/~perkr/awtcanvas.html
to see how to achieve this effect on a java.awt.Canvas. The case for a JEditorPane is the same, the basic idea is to make the panel paint in a BufferedImage that you then save to the fileformat you want.
To make it paint to an image you need to create a BufferedImage or RenderedImage instance of the same size as the panel whose content you wish to dump as an image file, see the following code snippet:
              Rectangle r = panel.getBounds();
              Image image = panel.createImage(r.width, r.height);
              Graphics g = image.getGraphics();
              panel.paint(g);
              ImageIO.write((RenderedImage)image, "png", new File(name));where "panel" referes to the JEditorpane. Note that the example uses the PNG format. I am not sure if default Java installations support TIFF yet (you can try) but I do know there exists a Java Advanced Imaging API (JAI) supplied by Sun that do support it.
Hope this helps.
