It's an autohinter -- it's doing the best job it can with the limited information it's got. The Freetype guys have done wonders with it over the last couple of years; it's not quite as good as a human type designer can manage yet, but in the latest releases it's often hard to tell the difference. I've found it's worth playing with unhinted font rendering if you're on a big display, though, since that avoids the glyph distortion that hinting introduces. David Turner and Jinghua Luo (among others) did some experimental work which used FIR filtering to produce extremely nice unhinted text rendering on subpixel-capable displays without the colour fringing that cairo/libXft usually produce; I've put the patches I'm currently using here: http://offog.org/stuff/cairo-fir.diff http://offog.org/stuff/libXft-fir.diff (If you want to see how this looks without messing with your system libraries, the Gargoyle IF interpreter has a built-in text renderer that uses the same approach: http://ccxvii.net/gargoyle/ Trying to figure out why Gargoyle's text looked nice on my display was how I found the patches above...) -- Adam Sampson <address@hidden> <http://offog.org/>
