GWT how to take a screenshot of a part of the browser window?

Question

Java

I have a button that, when clicked, should take a screenshot of a part of the browser screen and then I save it on the server. How can this be implemented?

Answer 1

You need to use html2canvas, this thing renders html on a canvas. From canvas, you can make a picture and crop it in the same place.

Answer 2

I would try using html2image https://code.google.com/archive/p/java-html2image/
maven https://mvnrepository.com/artifact/gui.ava/html2image
