Anyone who has spent more than 1 minute looking at aliased and antialiased fonts at the same (small) size will know this without having to be told, but the research supports it also. Readability is measurably improved. Some research *has* been done into the eyestrain issue. The initial indications are that antialiasing reduces eyestrain, but further work is needed. >It's not worth >doing unless you implement sub-pixel positioning, i.e. the ability to >place a character (logically) on a grid that is finer than the screen >resolution, using gray to "blur" it into the right place. Yes. That's why Sun's new GX graphics card implements quarter-pixel positioning for text and graphics. (Now if I could just afford a SparcStation to stick it in ... :-) Howard A.
