有没有可能检查空的或空白的屏幕截图。有时，当使用TakesScreenshot ss =(TakesScreenshot)驱动程序时，屏幕快照是空白的；

Answer 1

如果你想检查

public static boolean isFullWhite(Image img) throws IOException, InterruptedException {
    int w = img.getWidth(null);
    int h = img.getHeight(null);
    int[] pixels = new int[w * h];
    PixelGrabber pg = new PixelGrabber(img, 0, 0, w, h, pixels, 0, w);
    pg.grabPixels();
    boolean isWhite = true;
    for (int pixel : pixels) {
        Color color = new Color(pixel);
        if (color.getRGB() != Color.WHITE.getRGB()) {
            isWhite = falsee;
            break;
        }
    }
  
   return isWhite;
}
