PDF from Google Docs Template - Image/Margins Issues

[wjjunyor]

Hi folks, 

I am trying to configure an invoice PDF for a working app, almost everything OK, if it wasn't this huge margins and despite of every possible workaround, the result still the same: 

How can you see, I am not able to align this image to 0x0 position on page. Any hint?

Also, thanks in advance.
