ruler not 1:1

[Claus Atzenbeck]

Hi,

I use OmniGraffle on my 15'' PowerBook G4 with a screen resolution
1280x854.  The ruler shown by OmniGraffle at 100% magnification is not
1:1, that means that 1 cm shown by OmniGraffle equals approximately 0.7
cm in real live. Of course, the printing is correct.

Is there a way to adjust the ruler? There would be 2 ways:

(1) OmniGraffle recognizes screen size and resolution by itself and
calculates the correct size. (Would be best.)

(2) The user has to tell OmniGraffle manually what resolution and how
man dpi the computer uses. (This is OK if the screen resolution is not
changed. This is done by Gimp for example.)

Any idea or is there a hidden feature for that? If not, I would like the
Omni people to file this as a suggestion for the next release.

Greetings,
Claus
