Finally developed enough to test that section of the code, and it worked - woo hoo!
The pages from the PDF template were being inserted within the margins of the existing document, off to the right and bottom.
I tried setting Left to -2.5cm and Top to -5cm and that shifted the pages left and up, but still not high enough vertically.
Basically, it does not matter what value I put into Top: -2cm or -5cm, it is still the same vertical distance down from the top and is not moving any higher.
Is there any way to move the inserted image further up?
For this to work, will I have to save my original document into a custom paper size format with no margins and page size reduced by the margin widths? That would be very unfortunate, as the template is owned by non-technical folks.
Ah! Figured it's as simple as that:
Code:
section.PageSetup.TopMargin = "0cm";
section.PageSetup.LeftMargin = "0cm";
