Converting Image Text to Editable Text

[cldcp00]

Hi Guys
I have a Samsung Galaxy Note 10.1 2014 and wondered is there some way where you can capture some text from the screen and convert into editable text.

Example
From a Web page or from an Epub document in fact anything displayed on the screen. I can manage to capture the image, but cannot convert the text it contains into the text that I can edit.

Thanks in advance for any help
