TCPDF ImageSVG dynamic position in writeHTMLCell - php

Question

I am creating a pdf using TCPDF and everything is rendering the way that I want it. There is an area that is dynamic where it writes a variable number of lines. This area is rendered using writeHTMLCell. After this is rendered I want to place a signature image using $pdf->ImageSVG in the area marked '{SIGNATURE HERE}'. What are the dynamic coordinates based on variable lines ahead of it to place it in the correct position.
Thank you for any help.
