I'd say it is probably a feature of FontForge rather than a bug, to actually sum all the bound boxes. OTOH, surely global ascender /descender is not related to line-spacing at all? It is entirely conceivable, though extremely unlikely, that a font is, by design, having a lot of hanging-below and sticking-above bits, or having very line-spacings within nothing much between. I think the Zapfino font ( https://en.wikipedia.org/wiki/Zapfino ) is a good illustration of the "lots of hanging-below and sticking-above bits" idea... _______________________________________________ Freetype-devel mailing list Freetype-devel@nongnu.org https://lists.nongnu.org/mailman/listinfo/freetype-devel
