Methods

ArrangeOverride(Size)

Arranges a Shape by evaluating its RenderedGeometry and Stretch properties.

protected override Size ArrangeOverride(Size finalSize)

Parameters

finalSize Size

The final evaluated size of the Shape.

Returns

Size

The final size of the arranged Shape element.

DefinedGeometry()

Get the geometry that defines this shape.

Based on Mark Feldman implementation.

protected Geometry DefinedGeometry()

Returns

Geometry

PointAtAngle(double)

Draws a point on the coordinates of the given angle.

Based on Mark Feldman implementation.

protected Point PointAtAngle(double angle)

Parameters

angle double

The angle at which to create the point.

Returns

Point

PropertyChangedCallback(DependencyObject, DependencyPropertyChangedEventArgs)

Event triggered when one of the key parameters is changed. Forces the geometry to be redrawn.
