Re: [ft-devel] Patented bytecode interpretter and fallback to autohinter

I guess the ideal thing to do is to see the number of hinted glyphs for various fonts to get some idea about it. It's very probable that a font designer would add hinting for glyphs that only need them. So maybe just 10% of glyphs should be considered a 'yes.' Not sure of course. Mostafa On

On the other hand I see the problem you have. However, there is currently no possibility (built into FreeType, I mean) to find out whether a font has TrueType hints or not. It's straightforward to add such a function, and FontConfig might use it during the creation of the cache. That

Hi, In Fedora rawhide I enabled the patented bytecode interpretter a while ago since the patents expired. I've received reports since that this has resulted in degraded rendering of some fonts. Apparently, from what I hear, with Medium hinting, the autohinter is not used even if the font
