Apparently, there's a bug that affects PDF output for fonts with different funits/em values. Even microseconds add up if many operations are performed when rendering text for the screen on zooming in or reflowing text.įor Mac OX, 1,000 funits/em is recommended.
I think there is still a good reason for sticking to multiples of 2^ however fast modern computer chips may be, and in spite of Microsoft's recommendations being made in 2002. One foundry that deserves to remain anonymous (but not for that reason) uses 4096 funits/em.įile size increase for my Guru Italic font with 2,893 glyphs (and 1,265 composites) is as follows:

Note: This is a free app, but donations of 10 USD or more on the developer page are encouraged and allow you to download the commercial version of BirdFont, which allows you to create proprietary fonts. I have only come across a few that used 8192, and as I said Gabriola uses 4096. BirdFont is a free font editor that lets you create vector graphics and export TTF, EOT, and SVG fonts. Are there many fonts that do this? Is the only reason _not_ to that it will increase file size because you're using larger integers? Does that have that much of an impact? Thanks for feeding my curiosity. I presumed that the main reason for increasing the funits/em would be to support delicate features, but I never would have imagined going to 4096 or 8192 funits/em. Buka Bird December Bullet Journal, Bullet Journal Spread, Lilo Stitch, Lettering Fonts. On the other hand, perhaps it's better that the font editor not round off any transformation at all, except at the final TTF/OTF generation stage? Are there many fonts that do this? Is the only reason _not_ to that it will increase file size because you're using larger integers? Does that have that much of an impact? Thanks for feeding my curiosity.įor MM families is it better to use these higher numbers so interpolated instances are more precise and less affected by integer round-off error? Or does it matter? I guess it probably depends on the complexity of the design.
I presumed that the main reason for increasing the funits/em would be to support delicate features, but I never would have imagined going to 4096 or 8192 funits/em. Scripts with fine lines like Gabriola use 4096 funits/em. If a font contains very fine details, use a higher funits/em value.Īt 2048 funits/em very small circles will no longer be circular, so increase the value to 4096 or 8192 funits/em.
