c#代码

IWebDriver driver = new FirefoxDriver();
driver.get("http://www.google.com/");
File scrFile = ((ITakesScreenshot)driver).GetScreenshotAs(OutputType.FILE);

// Now you can do whatever you need to do with it, for example copy somewhere
FileUtils.copyFile(scrFile, new File("c:\\tmp\\screenshot.png"));

Java

这里似乎没有-在Java中截取一个特定元素的截图:

public void takeScreenshotElement(WebElement element) throws IOException {
    WrapsDriver wrapsDriver = (WrapsDriver) element;
    File screenshot = ((TakesScreenshot) wrapsDriver.getWrappedDriver()).getScreenshotAs(OutputType.FILE);
    Rectangle rectangle = new Rectangle(element.getSize().width, element.getSize().height);
    Point location = element.getLocation();
    BufferedImage bufferedImage = ImageIO.read(screenshot);
    BufferedImage destImage = bufferedImage.getSubimage(location.x, location.y, rectangle.width, rectangle.height);
    ImageIO.write(destImage, "png", screenshot);
    File file = new File("//path//to");
    FileUtils.copyFile(screenshot, file);
}
