How to create a new layer on top of existing PDFs?
Here's my need:
I would like to add a layer to existing diagrams (PDF format), where i can comment and draw additional mark up lines etc.
In case of an updated diagram (PDF), i would like reuse my own created layer. I.e. import the new pdf as a layer behind my own layer, or transfer my own layer to the new PDF.
Any solutions to this??
