With this change, the computation of the scale factor becomes identical across the freetype and truetype packages, removing deviations in the font metrics that are derived from scale. The rounding computation is newer; it was introduced when the truetype.Face type was added in commit 6deea24. Fixes #85.

I just noticed there's a return fixed.Int26_6(x * float64(c.dpi) * (64.0 / 72.0))We should not change one without also changing the other, as that would fix #85 but introduce another inconsistency within this package. Hmm. |
Otherwise there may be deviations between the scale computation and the conversion done by PointToFixed in the same package.
Yeah, that's unfortunate. :-/ |

…inding = true in rasterizer; return !ok in GlyphAdvance if rune index == 0, consistent with opentype.

Apply the same change to the Context.PointToFixed method to
keep it in sync.

truetype.Face type was added in commit 6deea24.
Fixes #85.
