A python version of Pablo Impallari's font family stem weights calculator for Robofont and GlyphsApp.
calculates and prints (three different sets of) stem values and the related interpolation values within a font family.
• Stem Values are calculated from the first stem of a reference glyph (e.g. "n") at a certain vertical postion (BeamPos) in two fonts (RoboFont) or two master layers (GlyphsApp).
• Or one can manually provide values for calculation in the script itself.
(for details take a look at OPTIONS in the script)
A Script for RoboFont and Glyphs App that creates a graph of stem weight calculations with DrawBot.
It draws 3 curves (Luc de Groot's interpolation theory, Pablo Impallari's proposal and a curve which lies in between both: the Schneider interpolation curve)
Requires the DrawBot extension:
GlyphsApp: https://github.com/schriftgestalt/DrawBotGlyphsPlugin
Robofont: https://github.com/typemytype/drawBotRoboFontExtension
