Re: Capture screen shot to file

Hello,

I am actualy working on a kind of "Common Browser API" (currently 
integrating JRex and JDIC, but there are plans for Konqueror and others).
To take a screenshot, using the Robot class works for JDIC (IE & Mozilla).
As I said in my previous mails, I have problems compiling JRex with 
MinGW, so I have not tested this way of doing with JRex, but maybe it 
can work.

--------------------------------------------------------------------------------------------------------------------
    try {
      this.robot = new Robot();
    } catch (AWTException awte) {
      awte.printStackTrace();
    }

    JPanel toShot = webBrowserPanel.getWebBrowserCanvasPanel();
    Rectangle rect = new Rectangle(toShot.getLocationOnScreen(), 
toShot.getSize());
    BufferedImage image = robot.createScreenCapture(rect);
    try {
      ImageIO.write(image, "png", new File("C:\\Documents and 
Settings\\Jean-Philippe\\Bureau\\shot.png"));
    } catch (IOException ioe) {
      ioe.printStackTrace();
    }
--------------------------------------------------------------------------------------------------------------------

If you want the complete canvas, you will have to scroll the page and 
recompose the image (I will integrate this functionnality later).

The new Gecko engine (not the one actualy used in JRex) owns a complete 
canvas API, it can generate a screenshot alone without the robot class.
In this case, JRex would have to be ported.
