implement the pencil input in pdf

Hi radaeepdf team,

I want to integrate the pencil input in my pdf file but i could not find any blog or forum regarding this . i tried with PdfViewController class of ViewLIb library method m_view.PDFSetInk(1); but unable to get pencil input

please help

What do you mean with "pencil input"? Our library is capable of simple free hand drawing but, if you're looking for a more complex drawing tool with pen size, eraser, color, texture, etc you should develop it on your own.

May you be more clear?

thank you for your reply . i am using hand drawing tool as writing but its works for visible page if i want o to scroll the pdf then unable to scroll untill not click on
other buttons . so is it way to write pdf at single click and exist at double click . is there any ontouch override method so that i can override it?
