Re: [ft] Bug in FT_Stroker ?

[David Turner]

Hello Marcus,

sorry for the late answer, but I really cannot reproduce the problem
with the current version of FreeType (and the stroker hasn't changed
since a lot of time anyway).

Could you send us a small/minimalistic compilable source that exhibits
what you're experiencing ?

Thanks in advance,
