* I used wqy-zenhei. Now I see it, this's a pretty old version: 0.8.34. Later versions have better bottom line alignment. http://sourceforge.net/projects/wqy/files/wqy-zenhei/ * Plain git freetype autogen.sh. I defined AF_DEBUG=1 at ./configure. Also I assigned _af_debug=1 at src/autofit/afmodule.c to read debug output. * I used freetype's ftstring. * The string is the text used to calculate bottom blue zone. The 2nd one, with flat bottoms. At 11pt, the bottom of the last few chars will clearly show the effect. I attached an pic with anti-alias off. anti-aliased version also shows the effect.
#!/bin/sh # vim :set fileencoding=utf-8 ./ftstring -m "主些因它想意理生當看着置者自著裡过还进進過道還里面" 11 ~/.fonts/wqy-zenhei.ttc ; exit ./ftstring -m "Y" 11 ~/.fonts/wqy-zenhei.ttc ; exit
