[ft-devel] ttfautohint: broken components when ARGS_ARE_XY_VALUES is false
Hi, When composite glyphs have components with ARGS_ARE_XY_VALUES false, i.e. arg1 and arg2 are matched point indeces, `ttfautohint --composites` incorrectly increments the second matched point index. It should only change the second matched point if the component glyph has changed point indeces instead of all the time. For example, when Molengo-Reular.ttf (from https://github.com/moyogo/molengo-fonts/releases/download/v0.10/Molengo-fonts-0.10.tar.gz) goes through ttfautohint --composites, the composite glyphs are broken. The gravecomb glyph does not have any point index changes. However it is used as a component in Agrave, while ttfautohint correctly increments the first matched point, i.e. the point index to match on the whole composite Agrave, it also incorrectly increments the second matched point index (arg2), i.e. the point index being matched on gravecomb. The first point needs to be incremented since a '.ttfautohint' component with one point is added as the first component. But the second point should not since no point index where changed in gravecomb.

The two fonts each have missing characters, but put together they make a full set. This occurs whether you select Mercury, Sentinel or Witney. One font has only EHINXdorsuwz12356890 etc., the other is missing those characters. It’s possible the two different fonts are hinted differently. -- Denis Moyogo Jacquerye ___ Freetype-devel mailing list Freetype-devel@nongnu.org https://lists.nongnu.org/mailman/listinfo/freetype-devel
Re: [ft-devel] New Microsoft size-specific design selection mechanism
The reason given for not using the 'size' feature is the lack of implementation and the fact that 'size' is a GPOS feature, not the best place for this.

Re: [ft-devel] Latin, Cyrillic, and Greek fonts questions
Hi, Some designers have Cyrillic with slightly taller x-height (sometimes by a minute amount) to adjust the squareness of the script relative to the roundness of Latin, even glyphs that are usually components have adjusted outlines. Other designers recommend components but different spacing (slightly larger side bearings) instead of x-height to address the issue.

[ft-devel] 2.3.5 TrueType hinting bug
Hi, There seems to be a bug due to 2.2 to 2.3 changes in TrueType hinting. See the example aring U+00E5 in DejaVu Sans Book [1] where the ring above isn't properly rendered at some size with freetype 2.3.5. The problem seem to occur wiht some MDRP instructions. This also happens with a few other fonts.
