I'm surprised that the output on screen doesn't look better.

Usually Quartz does an extremely good job...

Are there any other settings I can adjust with regard to the anti- aliasing? (Not talking about flatness of Bezier curves here). Is this perhaps due to the floating point user space to device space conversion? and/or non pixel-perfect rendering?

...though quite what "pixel-perfect" is supposed to mean when we're talking about anti-aliasing, I'm not certain.

Are you looking at the screen from an angle? Sometimes if you do that, it will de-emphasise the anti-aliasing effect, I find... if so, try looking at the screen straight on and see if that's better.

If that isn't the issue, maybe you need to re-post your question to quartz-dev instead, since that's the right place to discuss rendering issues like this.

Kind regards,

Alastair.
