[ft-devel] Where to find OpenType/TrueType font format specification or doc

[Aaron Elkins]

Hi forum,

I need some font formats (Both OpenType and TrueType) to understand how 
FreeType works, and It seems hard for me to find those specs/docs, can anyone 
point me the way to get those font specs or docs, the more the better.

BTW, I am going to write my own font parser & writer in C.

Best,
Aaron
