For NinjaScript development purposes, we document only essential members in the structure of this page.

 

 

Definition

Describes a geometric path that can contain lines, arcs, cubic Bezier curves, and quadratic Bezier curves.

(See also unmanaged API documentation)

 

Notes:  

1.To create a GeometrySink, describe a PathGeometry and retrive the object using the PathGeometry.Open() method
2.A geometry sink consists of one or more figures. Each figure is made up of one or more line, curve, or arc segments. To create a figure, call the BeginFigure method, specify the figure's start point, and then use its Add methods (such as AddLine) to add segments. When you are finished adding segments, call the EndFigure method. You can repeat this sequence to create additional figures. When you are finished creating figures, call the Close method.

 

Syntax

interface GeometrySink

 
Methods

AddArc()

Adds a single arc to the path geometry.

AddLine()

Creates a line segment between the current point and the specified end point and adds it to the geometry sink.

AddLines()

Creates a sequence of lines using the specified points and adds them to the geometry sink.

BeginFigure()

Starts a new figure at the specified point.

Close()

Closes the geometry sink, indicates whether it is in an error state, and resets the sink's error state.

Dispose()

Performs application-defined tasks associated with freeing, releasing, or resetting unmanaged resources.  (Inherited from SharpDX.DisposeBase.)

EndFigure()

Ends the current figure; optionally, closes it.

SetFillMode()

Specifies the method used to determine which points are inside the geometry described by this geometry sink and which points are outside.
