Could you elaborate? macOS doesn't typically do TrueType or CFF hinting. Kerning should be identical for modern rasterizers on all platforms nowadays.
- ggreer 8y agoThat was exactly the problem. The web font (a variant of Open Sans) had bad TrueType hinting, which macOS ignored. I viewed the site using Edge and it almost looked as if all antialiasing and subpixel rending was disabled.
- aasasd 8y agoTIL TrueType was developed by Apple, already with hinting as far as I can tell. Apparently the Mac font renderer ignores most of the hints but not all.
- pcwalton 8y agoApple's rasterizer doesn't do grid fitting, which essentially means it ignores the hinting instructions, but it does do pixel snapping in some cases.
