I am using Perfex to generate my quotes and invoices. Perfex utilizes the TCPDF library to create PDF documents. However, since this morning, the logo of my company no longer appears in the generated quotes.

I’m using TCPDF to generate a PDF document, and I’m encountering an issue where there’s an unwanted padding or space at the top of the table before the first row. Here’s the relevant code and a screenshot of the issue:

I created a signed PDF file by using TCPDF.
I used this function: setSignature()
Howerver I can not find any function to validate this signed PDF file.
Following example 52 of TCPDF documment, they guildle me to use Acrobat Reader but I want to do it by myself (without using another app).
