WebElement#getScreenShotAs(OutputType.File) not working

I am trying to use WebElement#getScreenShotAs(OutputType.FILE) feature added in selenium webdriver 2.47.0 version on Firefox Browser Code

public static void main(String[] args) throws IOException {
        WebDriver driver=new FirefoxDriver();
        driver.manage().window().maximize();
        driver.get("http://automationpractice.com/index.php");
        WebElement element=driver.findElement(By.cssSelector("a[title='Contact Us']"));
        System.out.println(element.getText());
        element.getScreenshotAs(OutputType.FILE);
        File destination=new File("Image.png");
        FileUtils.copyFile(null, destination);
    }

..But I am getting below exception:

The real reason for the error is that many / most WebDriver implementations do not actually support element-based screenshots, despite WebElement extending TakesScreenshot since 2.47.0. Perhaps someday this will change.

If you want screenshots you need to do them at the whole-browser level, in which case - as other answers have it - you need to pass the WebDriver instance.

File ssFile = ((TakesScreenshot)(driver)).getScreenshotAs(OutputType.FILE);

Strictly speaking you should probably do the following, since not all Drivers are guaranteed to support screenshots, e.g. HtmlUnitDriver.

if (!(getDriver() instanceof TakesScreenshot)) {
    File ssFile = ((TakesScreenshot)(driver)).getScreenshotAs(OutputType.FILE);
    // ...
}

There are alternate solutions for single-element screenshots, but they inevitably involve cropping of the full-browser screenshot. See, for example: https://stackoverflow.com/a/13834607/954442

Update: just to clarify that this is not a bug, it's that although element screenshots are a part of the W3C WebDriver spec, different browsers have different levels of compliance/coverage, and as far as I know this feature is only supported by Microsoft Edge.

The getScreenShotAs() method is not defined as part of the WebElement interface. Rather, it is included as part of the TakesScreenshot interface. If you want to take a screenshot and save it to a file, try the following:

File file = ((TakesScreenshot)driver).getScreenshotAs(OutputType.FILE);

It should be something like this.

File screenS = ((TakesScreenshot)(driver)).getScreenshotAs(OutputType.FILE);
FileUtils.copyFile(screenS, new File("C:\\akshay\\del\\screenshots\\1.jpg"));

replace the above code with

element.getScreenshotAs(OutputType.FILE);
        File destination=new File("Image.png");
        FileUtils.copyFile(null, destination);
