I'm creating a system in Asp.Net MVC and I need to create a scheme for the user to write his signature to a .pdf file that corresponds to a contract and I'm looking for a way to do it but I have not yet found it.
I saw that with iTextSharp it is possible to draw geometric shapes, but I have not found how to do it freely like a Paint Brush pencil for example.
I took a look at the Adobe SDK and Foxit but I have not found a way to do this, even though in the documentation it is possible.
How to do this?
