Can someone post a screenshot of each of the four different types of antialiasing in Jaguar? I'd like to see just what the idea behind them is. Are they like CoolType in Acrobat?

LCD

One of the big problems with anti-aliasing in OS X is that it doesn't look very good on LCD screens, which Apple is moving toward in every product other than the eMac. Instead of looking slearer, it just looks fuzzy. :cool:

cleartype sucks in xp

I have been using it and every time you scroll, or cause the a box or window to appear over the text, the text underneath loses the "clearness" the only way to rectify this is to highlight the text. it is a pain in the ass on webpages.

That's not really a flaw in the Cleartype "technology" (i.e. sub-pixel rendering), it's just that XP only applies anti-aliasing selectively (using vi in a terminal window on XP is a very weird experience) particularly where text boxes, etc, are concerned, and seems to have occasional problems with re-drawing parts of the screen properly.

However, when Cleartype works, it's definitely got an edge on the current OS X anti-aliasing in terms of clarity, the only downside is that you sometimes if you've got a sharp white to black transition you can see a reddish tinge on the left-hand side of the transition. There's presumably a corresponding tinge on the right-hand side of a transition from black to white (green or blue tinged, I can never remember the order of LCD elements).

I've seen some mention that one of the anti-aliasing options for Jaguar that's listed as "best for LCD" actually does sub-pixel rendering, not sure how true that is. It'd certainly be nice, since OS X doesn't appear to have any problems with anti-aliasing text as it's entered.
