I am writing to you all today because I have an interpolation issue (possibly a software bug).
I am creating a font family with multiple weights. The glyphs with flat edges on both sides have LSB and RSB values of 60 units for the lightest weight. The heaviest version of my font uses 30 units for left and right flat edges. Letters like “T” have consistent side bearings for both weight extremes (10 units on both sides).
If I view my font in an intermediate weight, the distance between a flat edge and the left side of the “T” is greater than the distance to a flat edge from the right of the “T.”
Any help troubleshooting would be much appreciated!
