calculateArrowheadSizes

public static Size[] calculateArrowheadSizes(Size startSize,
 Size endSize,
 double arrowLength,
 double arrowHalfWidth)

Calculates the two base coordinates of an arrowhead given a line segment. The arrowhead tip is at 'endSize'.

Parameters:

startSize - The starting Size of the line segment.

endSize - The ending Size of the line segment (arrowhead tip).

arrowLength - The length of the arrowhead (distance from tip to base).

arrowHalfWidth - The half-width of the arrowhead at its base.

Returns:

An array of two Size objects representing the base corners of the arrowhead. Returns null if the line segment has zero length (start and end Sizes are the same).
