Cubic vs. Quadratic

Post by jedbadda » Sun Jan 13, 2019 11:15 pm

Will converting contours from Cubic to Quadratic (or vice-verse) alter the shape/outline of the glyphs?

If I am copy-pasting glyphs from Adobe Illustrator, they will be Quadratic, correct? Any advantage to converting to Cubic if I am exporting the fonts as CFF?

And finally, will the fonts look better on screen as Quadratic or Cubic outlines?

  1. How the vectors are imported will depend on whether you selected TrueType Outline Format in Export Settings, or CFF Outlines
  2. Converting curves will alter the shape slightly. Try importing a vector with export options set to TrueType, then change the setting to CFF, and import it again. See screen shots below.
  3. CFF outlines do not support hinting, which might affect how they look on screen. Try each method, and see which you prefer. You can test a font in your target application without installing it by selecting the temporary font name generated in the Font Test Window while leaving the Font Test window open and switching to your target application.
