I am using pdftk in my web app.. first I am merging 3 pdf templates with fillable forms into one pdf template with fillable forms (let's call it 'simple.pdf').
Then, I want to go further and fill in 'simple.pdf's custom fields but I am getting the warning 'input PDF is not an acroform, so its fields were not filled'.. is it possible to preserve the 'acroform' attribute ?
Thanks !
