and now what happens if you're using a projector ? could you please factor in the distance to the screen and the field of view of the projector :)
just to say how scale is meaningless for pixel maps in an uncontrolled environment. nice hack by the way, but I'm not sure even your OS knows how many pixels it can fit in a screen inch. I think gimp makes you measure a line on the screen (with a real ruler) to configure that value. -- thomas On Tue, Dec 9, 2008 at 04:01, Rui Gomes <[EMAIL PROTECTED]> wrote: > Hi.
