Question

After experimenting with composite operations and annotation pdf on the canvas I’m now trying to remove annotation when a new page call.

How do I do this?

I need to clear the canvas for new annotations;

this can go on for a while so I don’t think annotation a new rectangle every time will be the most efficient option even as the PDF render every time when any page call…

so how do i clear the annotation to show the clear new page………

I had also used PorterDuff.Mode.clear this also did not work in my case…..

Answer 1

just call

 Canvas.drawColor(Color.BLACK)
