MakeThickenedTransformedCircle:
PROC [strokeWidth:
REAL, m: Transformation, thickening:
VEC ¬ [0.0, 0.0], minThickness:
VEC ¬ [0.0, 0.0]]
RETURNS [Pen];
A convenience; the translation part of m is ignored; thickening is in device space and can be negative (i.e. thinning is OK); minThickness is in device space and should be non-negative.
