Signing of PDF file

Hello There
We are researching a pdf processor for purchase. Following is what our web application need.
1 . One user of our site will put a placeholder for signature in the pdf document.
2. Later another user will actually insert a signature( or sign ) the pdf. At that time
the place holder should be replaced by the signature image.
The whole application is on web

Can this be done with aspose pdf? Please advice.

We would like to clarify that Aspose.PDF does not offer any viewer or UI based control to integrate with the applications. However, you can use it in codebehind in order to process the PDF documents. Along with that, adding image and signing the PDF documents is feasible using the API. Please check following article(s) in API documentation:
