Back
It _IS_ possible to fill in a PDF that has been "Reader Enabled" w/o
violating the rights - but it MUST be done in a very specific fashion
using "append mode" on the source PDF AND only modifying a limited
number of objects in the PDF.
So yes, if you are going to create a whole new PDF - you'll break the
"Reader Enabling". If you're careful about what you do, and how you
do it, you CAN accomplish your goal.
