Selenium: Not able to take complete page screenshot using aShot library

Question

Am trying to take the complete page screenshot both horizontally and vertically using Firefox gecko driver and aShot Library.

However, the results are not as expected. Take a look:

driver.get("https://google.com");

Screenshot fpScreenshot = new AShot().shootingStrategy(ShootingStrategies.viewportPasting(1000)).takeScreenshot(driver);
ImageIO.write(fpScreenshot.getImage(),"JPEG",new File("FullPageScreenshot.jpg"));

Looked into a lot of variants but nothing is working. Interestingly, when I try using old firefox version (46), I am able to take full screenshot without any third party library. Am trying to use latest firefox and have full screenshot functionality.

Any help?

While working with Selenium Java Client v3.12.0, ChromeDriver v2.40, Chrome v 67.0 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/:

Try:

Screenshot screenshot = new AShot().shootingStrategy(ShootingStrategies.viewportPasting(ShootingStrategies.scaling(1.75f), 1000)).takeScreenshot(driver);

where 1.75f is device pixel ratio (you can run window.devicePixelRatio; in browser console to find it). If it's still not capturing full screen, change it to 2f
