Is it possible to adjust the margin size?

[euoia]

Hey, thanks for this great application.

I am trying to print A1 (841mm x 594) using four sheets of SRA3 (450 x 320mm).

This allows for 46mm overlap horizontally and 59mm overlap vertically.

I think my printer should be able to manage this, since it can do borderless printing at this size.

When using pdftilecut as follows:

pdftilecut -in Live\ Music\ A1.pdf -out "out.pdf" -tile-size "320mm x 450mm"

The resulting page size is 24.89 × 33.08 cm and so requires 9 pages.

I wonder if this is due to the space required for the margin? Could we possibly have an option to adjust margin size, which could mean using fewer pages?
