Need to find X and Y coordinates in PDF

Hi Team,

We have a requirement to place a signature in PDF. We created two ways of solutions. Please find the below details,

1.Signature Component and PDF Utilities plugin.

2.Docusign integration As per my organization suggestion, Docusign needs to purchase a license. But here we want a solutions for R&D purpose. Hence we are not able to purchase any third party license.

We used signature component and PDF utilities(Image to PDF) to merge the signature into PDF.

Question: But we need to send X and Y coordinates to place a signature in right place in PDF. Is there any way of solution can User picks X and Y coordinates in Appian else share your suggestion too.

Thanks, Pradeep Sridharan
