如何使用Selenium WebDriver拍摄部分屏幕截图（框架）？

这应该工作：

import java.awt.image.BufferedImage;import java.io.File;import javax.imageio.ImageIO;import org.openqa.selenium.By;import org.openqa.selenium.OutputType;import org.openqa.selenium.Point;import org.openqa.selenium.TakesScreenshot;import org.openqa.selenium.WebDriver;public class Shooter{    private WebDriver driver;    public void shootWebElement(WebElement element) throws IOException  {        File screen = ((TakesScreenshot) this.driver).getScreenshotAs(OutputType.FILE);        Point p = element.getLocation();        int width = element.getSize().getWidth();        int height = element.getSize().getHeight();        BufferedImage img = ImageIO.read(screen);        BufferedImage dest = img.getSubimage(p.getX(), p.getY(), width,   height);        ImageIO.write(dest, "png", screen);        File f = new File("S:\ome\where\over\the\rainbow");        FileUtils.copyFile(screen, f);    }}
