CalculateSignedArea()

static double TPG.Utils.PolygonUtils.CalculateSignedArea ( Point[]  polygonAreaPoints )

inlinestatic

Calculate signed area of polygon.

Parameters

polygonAreaPoints

Polygon boundary

Returns

Positive area if polygon is defined using clockwise orientation of boundary, negative if orientation is counterclockwise. If Y increases upwards, sign is reversed

IsOrientationClockwise()

static bool TPG.Utils.PolygonUtils.IsOrientationClockwise ( Point[]  polygonAreaPoints, YAxisDirection  yad  )

inlinestatic

Check if polygon boundary is defined using clockwise orientation.

Parameters

polygonAreaPoints	Polygon boundary
yad	Y axis direction

Returns

true if clockwise
