Screen Graber Deamon

This was a hack to grab the questions from a paid online quiz. Idea here is, this program will run as a deamon in the background and take the screen shot every 10 second and save it into a jpeg file on temp directory.

public void captureFullScreen() { try { Robot robot = new Robot(); Rectangle area = new Rectangle(Toolkit.getDefaultToolkit().getScreenSize()); File target = new File(saveLocation, imageName + "_" + System.currentTimeMillis() + "." + imageType); saveImageToFile(robot.createScreenCapture(area), target); } catch (AWTException e) { System.err.println("Exception while capturing screen. " + e); } } /** * Saves the specified RenderedImage to the specified File. * * @param renderedImage the image to write to file. * @param target the file to write the image to. */ private void saveImageToFile(RenderedImage renderedImage, File target) { try { ImageIO.write(renderedImage, imageType, target); } catch (IOException e) { System.err.println(e); } }

and now the Deamon

public static void main(String args[]) throws InterruptedException { while(true) { new ScreenGraber().captureFullScreen(); Thread.sleep(10000); // will sleep for 10 seconds } }
