Drawing canvas allowing user to sketch images?

I am developing a project using CUBA-Platform and I need to allow my users to sketch (draw) images in an area on the screen and then save the image. Would also be good if they can bring up an existing image and annotate drawings on top of the image then save.

Is there this possibility in CUBA ? What can I do to make this happen ?

Thanks in advance !

If you know a JS component or library that does the job, you can use it in your generic UI screens. The simplest way to do it is to use Generic JavaScriptComponent.

Thank you !
