Methods
| Name | Description |
|---|---|
| ArcTo | Draws an arc to the specified point. |
| BeginFigure | Begins a new figure. |
| CubicBezierTo | Draws a Bezier curve to the specified point. |
| EndFigure | Ends the figure started by Avalonia.Platform.IGeometryContext.BeginFigure(Avalonia.Point,bool). |

| QuadraticBezierTo | Draws a quadratic Bezier curve to the specified point |
| SetFillRule | Sets path's winding rule (default is EvenOdd). You should call this method before any calls to BeginFigure. |
ArcTo Method
Draws an arc to the specified point.
public void ArcTo(Avalonia.Point point, Avalonia.Size size, double rotationAngle, bool isLargeArc, Avalonia.Media.SweepDirection sweepDirection, bool isStroked)
Parameters
point Avalonia.Point
The destination point.
size Avalonia.Size
The radii of an oval whose perimeter is used to draw the angle.
rotationAngle double
The rotation angle (in radians) of the oval that specifies the curve.
isLargeArc bool
true to draw the arc greater than 180 degrees; otherwise, false.
sweepDirection Avalonia.Media.SweepDirection
A value that indicates whether the arc is drawn in the Clockwise or Counterclockwise direction.
isStroked bool
Whether the segment is stroked
BeginFigure Method
Begins a new figure.
public void BeginFigure(Avalonia.Point startPoint, bool isFilled)
Parameters
startPoint Avalonia.Point
The starting point for the figure.
isFilled bool
Whether the figure is filled.
CubicBezierTo Method
Draws a Bezier curve to the specified point.
public void CubicBezierTo(Avalonia.Point controlPoint1, Avalonia.Point controlPoint2, Avalonia.Point endPoint, bool isStroked)
Parameters
controlPoint1 Avalonia.Point
The first control point used to specify the shape of the curve.
controlPoint2 Avalonia.Point
The second control point used to specify the shape of the curve.
endPoint Avalonia.Point
The destination point for the end of the curve.
isStroked bool
Whether the segment is stroked
EndFigure Method
Ends the figure started by Avalonia.Platform.IGeometryContext.BeginFigure(Avalonia.Point,bool).
public void EndFigure(bool isClosed)
Parameters
isClosed bool
Whether the figure is closed.
LineTo Method
Draws a line to the specified point.
public void LineTo(Avalonia.Point point, bool isStroked)
Parameters
point Avalonia.Point
The destination point.

endPoint Avalonia.Point
The destination point for the end of the curve.
isStroked bool
Whether the segment is stroked
SetFillRule Method
Sets path's winding rule (default is EvenOdd). You should call this method before any calls to BeginFigure.
