Remove processing-java window

usernamevalid

Im running processing-java from cmd line in another app. The app creates an image in an offscreen buffer, saves it and exits. However when ever the app is called there is still a window that pops up on screen, it takes focus away anything on screen. Is there a way to run processing-java with no window?

Thanks

void settings() {
  PImage img = createImage(300, 200, ARGB);
  java.util.Arrays.fill(img.pixels, #FF0000);
  img.save(dataPath("buffer.png"));
  System.exit(0);
}
