[JAVA3D] capture a canvas picture through a Swing component

[Olivier Tassy]

Hi, I have a java3d app wich run in a jFrame. I wrote a method wich allow the user to capture this frame and write it in a jpeg file. The problem is it captures the frame borders but not the canvas wich is inside.   Here is the code:     private void snapshotbuttonActionPerformed(java.awt.event.ActionEvent evt) {          File homedir=new File(System.getProperty("user.home"));         Dimension size = CanvasFrame.getSize();         BufferedImage myImage = new BufferedImage(size.width, size.height, BufferedImage.TYPE_INT_RGB);         Graphics2D g2 = myImage.createGraphics();         CanvasFrame.paintAll(g2);                                //same problem with paint(), print() or printall() classes          try {          OutputStream fileout = new FileOutputStream(homedir+"\\Capture.jpg");          JPEGImageEncoder encoder = JPEGCodec.createJPEGEncoder(fileout);          encoder.encode(myImage);          out.close();        }        catch (Exception e) {System.out.println(e);} }     Whats going wrong?   Thanks in advance, Olivier.
