QuadraticConverter is an extension for RoboFont that converts Cubic (PostScript) UFO to Quadratic (TrueType) UFO.

It might be installed manually (download and double-click) or automatically with RoboFont Mechanic.

• 0.7.4
  • Updated code to use ufolib from fontTools
• 0.7.3
  • Updated code to RoboFont 3 (Python 3, FontParts API, Mechanic 2)
• 0.7.2
  • Fixed potential weird behavior when cubic source layer is chosen in the popup button (UI bug)
• 0.7.1
  • Fixed crash when the font has less than 20 glyphs
• 0.7
  • Improved the low-level approximation technique. This results in much fewer generated control points
• 0.6.2
  • Improved sensitivity of the closeness of a quadratic and a cubic curve. This lowers the number of control points required for given precision
• 0.6.1
  • Added a button to convert a single glyph from an existing cubic layer. This is useful for fine-tuning a converted font (use the "Cubic contour" layer)
• 0.6
  • Faster by not using the slow contour.autoStartSegment()
  • Optimized code
  • Slightly better approximation in non-smooth segments
• 0.5.9
  • The conversion avoids inserting some inflection points
  • The approximation of a cubic by a single quadratic is more robust
• 0.5.8
  • Fixed wrong approximation when a handle has length zero
• 0.5.7
  • Improved behavior when glyph has both contours and components
• 0.5.6
  • Added option to subdivide the smooth segments by arc-length (enabled by default)
• 0.5.5
  • The contours are correctly orderer for the hinting to perform correctly
• 0.5.4
  • Converting a UFO will create a new UFO. Converting a non-UFO modifies it in place
  • In any case, the original contour is saved in the layer Cubic contour
  • New control for the minimum length of a quadratic segment
