--- Comment #10 from Henry Hu henry.hu.sh@gmail.com --- This simsun seems to have a strange GASP table. It says: (version 3.03 rev 2) ppem <= 8: no grid fit, aa ppem <= 24: grid fit, no aa ppem <= 65535: grid fit, aa It has bitmaps for 12, 14, 16
Another simsun from win8.1: (version 5.13) ppem <= 7: no grid fit, aa, sym-smooth, no grid fit w/ sym-smooth ppem <= 17: grid fit, no aa, no sym-smooth, grid fit w/ sym-smooth ppem <= 59: grid fit, aa, sym-smooth, grid fit w/ sym-smooth ppem <= 65535: grid fit, aa, sym-smooth, grid fit w/ sym-smooth It has bitmaps for 12, 13, 14, 15, 16, 17
With the new simsun it seems to work fine...
