Image exist activity question

Hi All,

We have a requirement where we need to search if a set of images exist in a PDF file containing scanned images. Below are our questions.

Does Image exist activity scan for the image in the entire PDF file or just the area of the PDF that is view-able on the screen? Do we need to have the bot scroll down and scan the rest of the file?
Any other alternative to Image exist you can suggest? We are getting inconsistent results when checking for the images. The bot sometimes recognizes a image which is not in the PDF.
Thanks for your help.

I think the Robot scans the specific area that is visible on screen to check for Images and you need to scroll down(RIght Arrow shortcut) to scan the rest of the file.

As long as the Image Exists selector is untouched (not even wildcard titles), Robot will not be able to detect the outside Image.

Thank you for the information. we are now planning to implement the scroll down solution.
