title: Digital signature in pdf file using reactJs
body: <p>I need to build an app that accepts pdf file from the user and place an image of a user image signature (which is already uploaded by the user) where a user clicks on pdf.
  same as Adobe reader provide a feature to add the digital signature.
  I am using ReactJs to build this app.</p>
  
  <p>Anyone know any clue how to do this.</p>
