msdfgen_edgeColoringByDistance⚠
The alternative coloring by distance tries to use different colors for edges that are close together. This should theoretically be the best strategy on average. However, since it needs to compute the distance between all pairs of edges, and perform a graph optimization task, it is much slower than the rest.
msdfgen_edgeColoringInkTrap⚠
The alternative “ink trap” coloring strategy is designed for better results with typefaces that use ink traps as a design feature. It guarantees that even if all edges that are shorter than both their neighboring edges are removed, the coloring remains consistent with the established rules.
msdfgen_edgeColoringSimple⚠
Assigns colors to edges of the shape in accordance to the multi-channel distance field technique. May split some edges if necessary. angleThreshold specifies the maximum angle (in radians) to be considered a corner, for example 3 (~172 degrees).
