milliradians (mrad). 1 mrad is the angle under which you see a 1 mm large pixel in 1 meter distance (or 1 cm large pixel in 10 m distance, etc.). Extremely simple, intuitive and convenient to use, especially when working with monitors as well as projectors. Example: I am sitting in front of a 320x240 mm large screen with 1024x768 pixels at a distance of 0.5 m -> pixel size is 0.3 mm and I can see it under 0.6 mrad. Anyone thinking about introducing new units of measurements on this planet, please read ISO 31-0 first, stick strictly to it and don't even think considering anything related to medieval US abdominations such as inch, point, or worst of all reciprocal length. The use of the units "point" and "dpi" makes the entire font selection business extremely userunfriendly. *PLEASE* don't do this in new APIs!!! Markus -- Markus G.
