Taking Screenshot coordination issues | Selenium Forum

Hi Ashish,

I was practicing the lesson on how to take a screenshot for a specific element from a webpage. I was able to capture the screenshot from this particular Xpath, however, it's not taking the image correctly, each time it will miss some part of the required image. I think between the JVM and Webdriver, there might be an issue with coordinating the image (height and width values) and not cropping the image accordingly. I have attached the code below. Could you please take a look at my code and advice me?

Thank you,

Ashik

Ok.. In this case if there is some outer div in which element is present then take screenshot of that div

Hi Ashish,

I took the screenshot of the most outer div but it still seems to have an issue with the cropping, please see the below image for more info. Thank you.

 

//*[@id=\"Header\"]

Hi Ashish, 

Please see the below screenshots. Browser is maximizing  as soon as the page loads yahoo.com. Also, I'm taking two screenshots. First one taking the full page, which is working but if I focuse on a particular area or element from the page, then it doesn't work(it only takes partial of the page as shown below). 

Thanks, 

Ashik
