equivalent to cleartype

Posted:
in macOS edited January 2014
winxp has this function "cleartype" which makes reading easier on LCD.



is there a similar function in OS X?

    The anti-aliasing that's on automatically in OS X is the closest you'll get to cleartype. AFAIK, there is no sub-pixel anti-aliasing on the Mac.



    Out of curiosity, which do you prefer, cleartype or X's anti-aliasing? Some people prefer one or the other. I'm still not used to the blur I get on this 17" LCD I'm using.

    I detest Cleartype, period. Unfortunately, the regular AA in Windows XP is not very good either.

    ClearType gives people headaches.



    Me included.



    Gimme Quartz AA. Looks like paper.

    I used to think XP's antialiasing was ugly, until I spent some time with it and discovered exactly how much more readable it is than OS X's. I really think people should benefit from being able to choose between readability and prettiness.

    I agree.



    Actually, there is a ClearType equivalent technology for MacOS, it's built into Adobe Acrobat 5.x and Adobe's type rendering engine "CoolType". I would guess that Adobe will roll out this implementation in other applications, because CoolType is a common technology between all of Adobe's apps.



    And yes, Apple did "invent" sub-pixel positioning.



    Real problem with all of these sub-pixel techs is that they canot really handle colour very well, black text on white backgrounds works best, reversing out text can look awful.

    To pick nits, it's based on the technology Woz created and patented for the Apple ][ monitors, but's not verbatim. MS got to develop ClearType as part of the deal with Apple five years ago -- it included patent sharing. Hey, remember what displays were like in those days? :eek:

    I'm not sure that patent sharing thing is true, MS were applying for a patent on their ClearType development.

    Patents only last 20 years, so if Apple patented subpixel font rendering it would have expired 3 or 4 years ago. But ClearType isn't the same as what the Apple ][ did anyway.

    Cleartype gives me headaches too. <img src="graemlins/hmmm.gif" border="0" alt="[Hmmm]" />



    I don't think any of my Windows buddies use it.

    There's a hack to switch off anti-aliasing in some situations, but IMO apple really dropped the ball for type rendering/choices in some situations in X.

    The antialiasing looks great on my CRT, but it seems virtually unreadable on a LCD (powerbook G4).



    You would've thought that Apple might have optimized it's OS for it's own monitors, but oh well.

    yeah, it times out after a while... basically it's a patent filing on behalf of Apple for ChromaType.
