Re: [NTG-context] insert natural table at the top left of some png

16 Oct 2018


      Thank you very much Hans !
One of my first thoughts today was using layers (did not think about
it earlier, because I was too focused on plain TeX boxes), but I am
quite new to this topic.
Thanks to your code, I will have time to learn how to use them.

Greetings,


Damien Thiriet
