A few years back there was a sample code app that would use a key

Sorry, in the last message I posted some stupid code which was written too late

Thanks David. My users are used to very crisp fonts from previous releases of
my software, so some of them are asking why the new version is not quite as
good as the previous one. I'm pretty much taking your reply to mean that I'm

Sometimes the layer is transparent, and sometimes it will have a color drawn
behind where the text is (not a background color for the layer though). The
superlayer is transparent, but behind that is an opaque view.
Even where there is an opaque fill drawn behind the text on the layer, it's

Do you draw a background for your text? If you are drawing over transparency
then sub-pixel antialiasing doesn't work and when you do the final composite
