I want to overwrite a existing PDF file, instead of creating a new one. I don’t want to draw the entire PDF file but only one page if there are hundred pages in PDF file.
Actually, I want to place some images on a page of PDF files . It would be wrote over if user tap the save button . Isn’t it possible ? Is there any framework or sdk ?
Thank you for any replies.

It’s not possible to reopen and continue editing a PDF file . Only read and redraw whole PDF again .
