Set Signature Field based on specific text-part

[MichelFreek1]

Hello,

I am new to Spire.PDF and was wondering if the following scenario is possible:

I have a specific text on my .pdf that gives me the information where I should put the Signature template.
E.g. "Signature Field" is the text and is placed in the middle of the document. (see picture)

Is it now possible to search for "Signature Field:", identify its coordinates, and then create a new signature template and place it below the "Signature Field:" Text based on the coordinates of the Signature field? (see picture)

The advantage would be that I do not have to identify the coordinates by my own but could just define a certain "keyword", identify it's coordinates and add maybe +10 in the PosY and then have the place identified where I want to place my signature.

Thank you for your help.
