Convert a Graphics2D to an Image or BufferedImage

I have a little problem here.

I have an applet, where user can "draw" inside it. To do that, I use the java.awt.Graphics2D. But, how can I do to save the user draw image as a JPEG image, or at least, convert it to a BufferedImage or something? I don't know how to do that.

Thanks.

Solution

  • I do it that way, and works very well:

    BufferedImage awtImage = new BufferedImage(drawPanel.getWidth(), drawPanel.getHeight(), BufferedImage.TYPE_INT_RGB);
Graphics g = awtImage.getGraphics();
drawPanel.printAll(g);

try
{
String caminhoImagem = System.getProperty("user.home") + "\\temps\\assinatura.jpg";
FileOutputStream fos = new FileOutputStream(caminhoImagem);
JPEGImageEncoderImpl j = new JPEGImageEncoderImpl(fos);
j.encode(awtImage);
fos.close();
} catch(e) {..... }

    That's all :) Thanks everyone :)
