Method TransformBy

Namespace: GeometryHelper.Geometry

Assembly: GeometryHelper.dll

TransformBy(GeoTransform2)

Gets the loop under a transformation.

public GeoPolygonArc2 TransformBy(GeoTransform2 transform)

Parameters

transform GeoTransform2: The transformation to apply.

Returns

GeoPolygonArc2: The transformed loop.

Remarks

Mirroring turns every arc the other way, so the bulges change sign, and the mirrored vertices trace the opposite winding, so a loop that ran counter-clockwise comes back clockwise. A transformation that scales the axes differently would make an arc part of an ellipse, and is refused.

Exceptions

ArgumentNullException: Thrown when the transformation is null.
InvalidOperationException: Thrown when the transformation would stretch an arc into part of an ellipse.
