Can this be done?
Somthing like this:
open existing PDF
find marker like ##insert graph 1 here##
insert the image 1 in to the PDF
find marker like ##insert graph 2 here##
insert the image 2 in to the PDF
Save the PDF as a new PDF
Sorry this feature is not supported. You have to specify the position of the image by yourself. We will try to support this feature later.
