What do you mean by "kern automatically"?
I have a few urdu ligatures that I wanna kern automatically. Only problem is: I dont know how to do it! I have seen snaps of Aziz Mustafas ''Reyhan.otf''. Although he hasnt use many ligatures, still his kerning was good between words.... Thats why I am begging u professionals for some advice in kerning of several ligatures. I have following font editors installed: FontLab, FontCreator, Fontographer....
Thnx....................
