Hi Radaeepdf team,

Thanks for release this beta version of library but its could not work for added text as well if i use frequently ink 100 times then tried for undo its work only 2 or 3 time and then message "no more undo" however ink lines still at pdf pages

how can i do that?
please help

Hi,
I have tested it with 100 inks and redo/undo works properly.

Can you reproduce it with all the pdf? all devices?
Can you please tell us the steps to reproduce it?

Hi davide ,
I am using google nexus 4 .steps are following

1 select ink input
2 draw line , then draw triangle,then draw square,then draw straight line,
3 then tap on undo button . sometimes its remove all draws things at a time . sometimes its show message " no more undo"
4 My expectation is that it should remove straght line first then sqaure then triangle etc but its does not .. can i do that?
