Usually Quartz does an extremely good job...
I know. That's why I'm confused.
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.
... just clutching at straws? I mean if 'it' was deciding on shading
values for 'pixels' assuming there were 72 ppi for example, whereas
actually I have about 110 ppi, it's conceivable that 'something' was
making a mess of things...
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.
No.
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.
Thanks I'll try that. I was hoping I'd made a cocoa blunder :-)
