Re: [ft-devel] freetype opengl texture

[David Turner]

Hello,

I thought the documentation made it clear that FT_RENDER_MODE_NORMAL corresponds
to 8-bit gray maps with 256 levels of "gray"

see: 

http://www.freetype.org/freetype2/docs/reference/ft2-base_interface.html#FT_Render_Mode

hope this helps,
- David
