How to take full page screenshot using AShot library through Selenium and Java

Question

I tried the below code for taking full page screenshot. But only the visible area is captured,

public void Fullscreen (WebDriver driver) 
{
    try {
        final Screenshot screenshot = new AShot().shootingStrategy(ShootingStrategies.viewportPasting(1000)).takeScreenshot(driver);
        final BufferedImage image = screenshot.getImage();
        ImageIO.write(image, "PNG", new File("D:\\" + "AShot_BBC_Entire.png"));           
    } catch(Exception e){
        System.out.println(e.getMessage());
    }
}

While working with Selenium Java Client v3.14.0, ChromeDriver v2.41, Chrome v 68.0 using ashot-1.4.4.jar here is an example to take the complete page screenshot both horizontally and vertically using ChromeDriver and aShot Library of the url https://jquery.com/:

• Code Block:

  import java.io.File;
  import javax.imageio.ImageIO;
  import org.openqa.selenium.WebDriver;
  import org.openqa.selenium.chrome.ChromeDriver;
  import org.openqa.selenium.chrome.ChromeOptions;
  import org.openqa.selenium.support.ui.ExpectedConditions;
  import org.openqa.selenium.support.ui.WebDriverWait;
  
  import ru.yandex.qatools.ashot.AShot;
  import ru.yandex.qatools.ashot.Screenshot;
  import ru.yandex.qatools.ashot.shooting.ShootingStrategies;
  
  public class ashot_CompletePage {
  
      public static void main(String[] args) throws Exception {
  
          System.setProperty("god.bless.you", "C:\\Utility\\BrowserDrivers\\chromedriver.exe");
          ChromeOptions options = new ChromeOptions();
          options.addArguments("start-maximized");
          options.addArguments("disable-infobars");
          options.addArguments("--disable-extensions"); 
          WebDriver driver =  new ChromeDriver(options);
          driver.get("https://jquery.com/");
          new WebDriverWait(driver, 20).until(ExpectedConditions.titleContains("jQuery"));
          Screenshot myScreenshot = new AShot().shootingStrategy(ShootingStrategies.viewportPasting(100)).takeScreenshot(driver);
          ImageIO.write(myScreenshot.getImage(),"PNG",new File("./Screenshots/elementScreenshot.png"));
          driver.quit();
      }
  }
