I tried the 3rd method again:
I created 2 attributes on the Business Object - Signature and Signature Thumbnail. I have a form which displays both the attributes and then I collect the signature on both of them to check how it would work on the PDF report. Once the form is saved, I generate the PDF report out of it and then I find that both the signatures are of the same size and has not made much of a difference.
Which attribute should be displayed on the form to collect the signature from the user so that the scaled smaller image is displayed on the PDF report?
Also,I found that even if I display the regular Signature attribute on the form, only when the mouse is used to sign on the top left corner of the box, then the signature is displayed on PDF. If the form is signed somewhere in the middle then it is not displayed.
Please let me know if there is anything missing / wrong in this approach.
Thanks,
Ramya
