Document Processing/Creation

Hello, I hope someone can help me out with this, since I was not able to find an answer to my questions in the documentation that I read on your site. Here is what I am trying to do: 1. Take existing PDF document and add all required placeholders/signature fields to it. 2. Determine location of each of these fields (x and y positions) 3. Save this document as a template so that I can later use it when creating a package in .Net to send to you for handling the document signature. 4. If this possible, is there a template document id that I can reference when adding the document to the package prior to sending it to your service? On the other hand, it would also be fine, I don't store the document at your site, but store it locally. The only thing that I don't want to do is I don't want to specify location of every placeholder field/custom field/signature field in the document by specifying x & y coordinates of that field in .Net code. If this is not possible, then somehow I would need to know how to determine what these coordinates are while creating a template for this document on your site Thanks, Max
