Re: [Devel] Problem with drawing of Japanese characters ( the face size is 10 )

[David Turner]

Hello,

I don't know FTGL enough, but it might be that your font includes
embedded bitmaps for character sizes < 22. By default, FreeType
returns the bitmap instead of the outline. I suspect that FTGL
is not checking this or using the FT_LOAD_NO_BITMAP flag when
loading the glyph image.

Well, maybe I'm wrong too, but until we get more details, it looks
like a FTGL bug rather than a FreeType one...

Hope this helps,
