Re: [ft] Font rendering quality

[Tudor, Dacian]

Hi all,

I have integrated version 2.5.0 and enabled TT_CONFIG_OPTION_SUBPIXEL_HINTING 
and we get perfect results. All the distortions are gone. Thanks a lot for your 
support!

Regards,
Dacian

Well, I think the hinting is amazing, actually: The font doesn't contain a 
single DELTA instruction, and the B/W rendering is very good globally.  Of 
course, the cost for this is extreme distortion of the glyph outlines (before 
rendering), and no chance to get decent results with AA rendering.
