注解

PathGeometry个对象都定义对象PathFigure的集合。Each PathGeometry object defines a collection of PathFigure objects. 每个PathSegment ArcSegment LineSegment对象都由一个或多个对象组成,如和,它们实际定义其形状。 PathFigureEach of the PathFigure objects is composed of one or more PathSegment objects, such as ArcSegment and LineSegment, which actually define their shape.

的填充PathGeometry区域是通过获取所有包含IsFilled PathFigure的对象(其属性设置为true ),并应用FillRule来确定封闭区域来定义的。The filled area of the PathGeometry is defined by taking all of the contained PathFigure objects that have their IsFilled property set to true and applying the FillRule to determine the enclosed area.
