Unfortunately, this only takes a boolean (not the 4 levels the user
can specify in the Appearance panel) and while setting it has *some*
effect on the text that is rendered, it's only a pale approximation of
what is seen on the screen (I'll accept an argument that all that is
needed is a boolean because the end-user gets to choose the *amount*
of smoothing but the call doesn't duplicate what's on the screen
either way).
So, has anyone else run up against this? What was your solution?
I haven't seen an answer to this, so I'll venture my guess: font
smoothing has special modes that use LCD sub-pixel rendering. These
can only work when you are actually going to the screen. Take a screen
grab of some text from an LCD screen with special LCD-only smoothing
turned on. Then magnify that grab. You will notice that the pixels
are colored.
Google "cleartype" for more information.
Cheers,
Marcel
