Re: [ft] freetype render mingliu.ttc

[Peter Hanzel]

Hello.

I have just discovered that using FT_New_Face(library, "mingliu.ttc", 1, 
&face) I get correct advance for glyphs. So latin are proportional and so 
on.
So the algorithm is good. But using FT_New_Face(library, "mingliu.ttc", 0, 
&face) I get always advance = 17 << 6.

Mingliu.ttf has two faces. Mingliu and PMingLiu.
My freetype is version 2.3.9.

Regards.
