I try to use PDFNetAndroid to filling signature fields and i saw some examples that sign these fields by code(not by human). e.g http://www.pdftron.com/pdfnet/samplecode/DigitalSignaturesTest.java.html
I want in the moment that the client touching the mobile screen on signature field it's opening with window or something and the client drawing on the filed.
Someone know how to do that?
UPDATE: I have pdf file with signature field that i was created by acrobat. I want to sign on the field in my android device. enter image description here
Thanks.
