是否可以使用WebDriver在框架集中拍摄仅一帧（而不是整个窗口）的屏幕截图？

或者，是否可以为屏幕截图定义窗口坐标或之后裁剪图像？

回答：

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);
    }
}
