I was concerned about loss of quality doing the rotation in raster space, particularly due to all of the trouble to get the hinting just right. (Though I'm not sure how much hinting to a grid matters when the glyphs aren't actually parallel with the grid anymore.) I suppose it's worth some experimentation, though, as that is definitely the path of least resistance. > One couldn't rotate individual > glyphs in a larger expression this way, but by far the most common > use case is to rotate the entire expression so this limitation doesn't > concern me much. Agreed. My usual response is: TeX doesn't support it, so why should we? ;) Cheers, Mike ------------------------------------------------------------------------- This SF.net email is sponsored by: Splunk Inc.
