OK, I have the strangest problem. I'm drawing text with ATSUI via
ATSUDrawText, but the text is not being anti-aliased. I know this
because when I use universal access to zoom way in, it's clear
there's no aliasing. On top of that, the text just looks terrible:
the tracking and spacing of some glyphs seems to be just wrong.
FWIW, I've seen this happen when drawing very small text. Probably
font sizes that fall below the minimum text smoothing size set in the
system preferences. I haven't noticed this in a some time but I don't
know if it's changed or if it's because I've set my text smoothing
preference to the minimum value.
Hmm... yeah, that could be it ... I'm dealing a 6.5 font size, though
in this particular test case the context is scaled 400%. And sure,
enough, once I changed the point size to 26.0 and changed the
document's scale back to 100% the text looked correct.
This is quite a problem. Yes, in this case, I'm drawing 6.5 pt type,
but two questions:
1) Why does tracking get completely borked? Especially on spaces?
2) Shouldn't Quartz realize that the context is scaled and that the
type is ultimately coming out at 26 pt in this particular case?
At least I know I'm not going nuts now. So... the next question... is
there a way I can programmatically force anti-aliasing in these cases?
I thought that's what kATSLineApplyAntiAliasing was for, but that
doesn't seem to be the case.
