[tex-k] Dvips: how to make -O option not to use 1in,1in offset?

[Igor Liferenko]

Hi,

I need to change -O option of dvips to count from top left corner of
page, not from 1in,1in offset.

I could just subtract this 1in from hoff/voff, but I'm not sure if
some rounding issues may appear. It would be cleaner to avoid adding
this offset in the first place. Does anybody know the place in the
source code where it is added?

Regards,
Igor
