Can anyone share a bit of the implementation details behind - [NSArrtibutedString drawInRect:]? I'm using it in -[NSView drawRect:] to place some text for printing.

I need to know the outputted text's height, but -[NSLayoutManager usedRectForTextContainer:] mysteriously cuts off the bottom 1/3 of the last line or two (depending on the size of the string). I figure this must be because of some sort of padding that's added to the string in -drawRect:, but I can't find any details as to how - drawRect: renders the text, so I don't know what variables I need to account for.


Take a look at Aki's post on typesetter behavior. That seems the most likely explanation of the discrepancy you are seeing.
