As well as a minimum physical size based upon viewing distance and eyesight, you also need a minimum number of pixels, regardless of the size (subtended angle) of those pixels. Satisfying the former constraint doesn't automatically mean that you will satisfy the latter. Also, it's not as if either "minimum" is an absolute. There's a difference between being able to read something and being able to read it comfortably. Between the two, other factors may come into play. If I'm reading text formatted to e.g. 80 columns, and the "comfortable" size only gives me 70 columns, a slightly smaller font would almost certainly be preferable. An obsession with physical size makes no more sense than an obsession with pixel sizes. Actually, it makes less sense. At least the historical fixation on pixel sizes had a rational basis: rescaled bitmaps look so bad that they're almost never useful. -- Glynn Clements <[email protected]> _______________________________________________ xorg mailing list [email protected] http://lists.freedesktop.org/mailman/listinfo/xorg
