How to use a graphic tablet for signature in Delphi

Hello,

I have a software written in Delphi 2010.

My customer  wants this:

- he goes to his customer and use a graphic tablet as Genius EasyPen i405X (but it can be other graphic tablet as well, he hasn't decided which) and the customer writes down his signature
- he would press a button in my software and my software:
1.needs to import the signature in a folder in jpg format (I don't know how)
2.store it in database (this is not an issue)

So there should be a communication between my software and the  graphic tablet.
The customer doesn't want to save the file himself to a certain place, he wants everything to happen with only one mouse click.

Can you help me?

Thank you

I solved the problem in a much easier way:

-I created a form on which can be drawn with the mouse (on the canvas)

-So when to user draws on the tablet it will draw direcly on my form too

-Whe he presses a button I save the canvas of the form in jpeg

you need a spec on the graphic tablet.
the graphic tablet will probably determine what "dev" environment you need to supply the software in

if it's a windows tablet you won't have a problem

otherwise you'll need a XE3 delphi to be able to develop for Ipad, Android, etc ...
or have the tablet open a website, where the signature is saved to a jpg
the website can just as well save the jpeg to a database

The customer will buy the tablet I will tell him (so he said).

By graphical tablet I don't mean not Iphone or Android but simple tablets which can be connected to a Pc and have a special pen I can draw with like it would be a sheet of paper and the drawing would be directly digitalized on the computer.

The cheapest graphic tablets are http://www.wacom.com/products/pen-tablets/bamboo

You will need to use OpenGL then as far as I know and receive the input from the tablet.

remember that will only work if you have a windows graphic tablet
or compile it with firemonkey (XE3) for other platforms
