Hello Paco,
you can render the contents of a component into an image
by doing something like this:
Component comp;
comp = ... // create your component, set it's size, etc
BufferedImage bi = new BufferedImage(comp.getWidth(),
comp.getHeight(),
BufferedImage.TYPE_INT_RGB);
Graphics g = bi.getGraphics();
comp.paint(g);
Now image 'bi' contains the data you needed.
Thank you,
Dmitri
