C# Class Perspex.Media.StreamGeometryContext

Describes a geometry using drawing commands.

This class is used to define the geometry of a StreamGeometry. An instance of StreamGeometryContext is obtained by calling StreamGeometry.Open.

Inheritance: IDisposable

QuadTo ( Point control, Point endPoint ) : void	Draws a quadratic Bezier curve to the specified point
StreamGeometryContext ( IStreamGeometryContextImpl impl ) : System	Initializes a new instance of the StreamGeometryContext class.

Draws an arc to the specified point.

public ArcTo ( Point point, Size size, double rotationAngle, bool isLargeArc, SweepDirection sweepDirection ) : void
point	Point	The destination point.
size	Size	The radii of an oval whose perimeter is used to draw the angle.
rotationAngle	double	The rotation angle of the oval that specifies the curve.
isLargeArc	bool	true to draw the arc greater than 180 degrees; otherwise, false.
sweepDirection	SweepDirection	/// A value that indicates whether the arc is drawn in the Clockwise or Counterclockwise direction. ///
Résultat	void
