◆ LW_LINEARIZE_TOLERANCE_TYPE

Semantic of the tolerance argument passed to lwcurve_linearize.

Enumerator
LW_LINEARIZE_TOLERANCE_TYPE_SEGS_PER_QUAD 

Tolerance expresses the number of segments to use for each quarter of circle (quadrant).

Must be an integer.

LW_LINEARIZE_TOLERANCE_TYPE_MAX_DEVIATION 

Tolerance expresses the maximum distance between an arbitrary point on the curve and the closest point to it on the resulting approximation, in cartesian units.

LW_LINEARIZE_TOLERANCE_TYPE_MAX_ANGLE 

Tolerance expresses the maximum angle between the radii generating approximation line vertices, given in radiuses.

A value of 1 would result in an approximation of a semicircle composed by 180 segments
