Addendum to my first post:

This does only work properly if the PlotRange of the graphics object is
set to reflect the values of "format" (had not used that one in a while).

So making sure your dimensions are correct by using ghostview is always
a good idea ;-)

So the right way to use this is:

gfx = Graphics[Line[{{10, 10}, {110, 10}, {110, 110}}],
  PlotRange -> {{0, 200}, {0, 200}}]

ExportScaled[filename_, gfx_, format_: {210, 297}, opts___?OptionQ] :=
  Module[{mm}, mm = 72/25.4;
  Export[filename,
   Show[gfx, ImageSize -> format*mm, ImageMargins -> 0,
    ImagePadding -> None, AspectRatio -> Automatic], opts]]

ExportScaled["test.eps", gfx, -Subtract @@@ (PlotRange /.
     Options[gfx, PlotRange])]

It is a good idea to set the PlotRange values for your graphics object
*explicitely*, because extracting the with FullOptions can result in
added whitespace (at least in some cases).

Regards,
Yves
