If you don't need just the exact image, you can take a screenshot and save it directly, but that will capture the entire screen and not just the image. In addition, you'd need to make sure the page was in focus and not minimized or it would be a screenshot of whatever was in focus. I'm attaching an example using the image I found on Google.com (doodle of the day).
Basically what we want is - From my PEGA application , I go to an external webpage. In the webpage , I (copy/download) a particular image and bring it back to the calling PEGA application and embed in one particular place in the PEGA UI .
Intention is similar to that of like copying a textual content (Ctrl+C) from the external web page and pasting(Ctrl+V) in the calling application.
This entire task should be automated.
Also please note , taking a screenshot of the entire page will not serve our purpose as we need only one image which is present in the screen.
Please let me know if this is possible in open span(RDA) .
