The server is sending base64 encoded string and the requirement is that the
ArcotForm js would assign this encoded string to the image and hence
displays an image at runtime.
You are correct. I followed this approach as reader 8.1(Security update from
adobe) or later doesn't allow the HREF approach.
This is the reason why I want to use XFA form as I was able to achieve
runtime image display by using ImageField not by AcroForm.
You can only have one type of form in a PDF – either AcroForm or XFA, you
can NOT have both. As long as you have XFA, that will cause Acrobat/Reader
to ignore any AcroForms that you have created. In your case, that’s the
pushbutton, which is why it doesn’t work in #3, because as far as
Acrobat/Reader is concerned, it doesn’t exist. If you want to add a button
to your XFA-based form, that’s fine too – you just have to do it using lower
level functionality with iText and XFA/XML.

I was using XFA form to only display the image rest everything is done
through Acroform(iText) .
Can you give any work around or suggestion to achieve this?
