That seems relatively complicated for what I want to do.
I see what you are saying. All I really want is that image that you get once you digitally sign to imprint in multiple fields, not necesscalry duplicating the signature itself.
The reason why this is important is that when I print this and hand it over, those who look at it know it was signed by an individual. The signature will be on multiple pages, not just one page.
If you don't need the "digital" part of the "signature" and all you need to do is have a visual representation of a signature, you can use buttons that use a signature image as an icon and then copy the one button's icon across the multiple buttons.
There's an example of copying button icons here http://livedocs.adobe.com/acrobat_sdk/10/Acrobat10_HTMLHelp/JS_API_AcroJS.88.732.html
Can you check my code?
I have the signature block excecute this code once the digital signature is input: it is not generating the icon:
var f = this.getField("Signature1");
var g = this.getField("Button2");
var temp = f.buttonGetIcon();
I do not think this is possible.
I tried running varations of the code, it will not grab the signature icon and populate it in the button for further reproduction.
Maybe I must give you an answer, which is not liked:
The purpose of a digital signature is to check, whether the PDF or a defined block of the PDF form (since A6 / AR6 for PDF, since A 8.1.2 / AR 8.1.2 for XFA PDF) has being changed since signature creation. To copy an image of an already existing digital signature means:
YOU ARE CHANGING THE SIGNED DOCUMENT / FORM !!
Digital signatures and their images (appearance internally) are unique and cannot be copied. During creating digital signatures, the structure of the PDF is being changed and the additional dictionary "V" is being created within the SigField. SigFields are COS-Fields (PDF Fields), even if some properties are available by JS. Forget about copying from that "V" dictionary .
If a visible signature image is a "nice to have feature" then maybe you should try ink signatures, but I have no experience with those.
