Signature Capture is a cool c# code for client which will allows you to draw a signature and save that in a .txt file that can be reloaded at a later time. The .txt file can be converted to a .jpg file with java code.

MainForm.cs is the c# Form which capture the signature. It collects and displays a signature which is made up of a list of line segments. Each segment contains an array of points (x and y coordinates). Drawing is done to a memory bitmap to prevent flickering.

It has Clear Button, Load Button and Save Button which incorporate the code.

SignatureControl.cs is a control class which gives lots of properties and methods to capture the signature from the form.

It's nice that you can capture someone's signature, but I don't see how you can tye this to a particular data record. If you save someones signature, what's to keep you from attaching the signature file to another fraudulent data record. All this does is provide a client/customer with a false sense of security, when in fact it's less secure. The correct way (and therefore more difficult way) to do this is to take the data from the data record and the signature and digitaly sign it with the customers private key. well blah, blah, blah just showing off my knowledge, I'm sure some expert in the field will come along and put me in my place. But maybe I'm missing something, what is the point of capturing someones signature like this?
