I can generate a PDF ,but now i want to update the pdf where i can add a signature.

2. I can use the signature pad .. but how to add the signature to the generated pdf?

Use case : customer receives a summary of a PM order ( which materials are used/ hours ..etc), and can add a signature.

Any tips/suggestions?
