customize the PDF export?

[gooper]

Hi Forum.

How can i customize the tcpdf that is generating the output?

I have sucsessfully changed the logo (could be used a jpg instead of the png, if you have problems with creating a working one ) but i can not really change the layout.

I assume that this is somewhere to customize. I would expect to have one php file that is called when i press the button.
