Overload Details

Overload 1

procedure Ellipse(Rx, Ry: TFloat; Steps: Integer = DefaultCircleSteps); overload; virtual;

Appends an ellipse centered at CurrentPoint with radii Rx and Ry.

Parameter	Type	Description
Rx	TFloat	Horizontal radius.
Ry	TFloat	Vertical radius.
Steps	Integer	Number of linear segments used to approximate the ellipse (default is DefaultCircleSteps).

Overload 2

procedure Ellipse(const Cx, Cy, Rx, Ry: TFloat; Steps: Integer = DefaultCircleSteps); overload; virtual;

Appends an ellipse centered at (Cx, Cy) with radii Rx and Ry.

Parameter	Type	Description
Cx, Cy	TFloat	Center X and Y coordinates.
Rx, Ry	TFloat	Horizontal and vertical radii.
Steps	Integer	Number of linear segments used to approximate the ellipse.

Description

Ellipse constructs an elliptical closed polygon path with horizontal radius Rx and vertical radius Ry and appends it to the path builder.

• If center coordinates (Cx, Cy) are omitted, the ellipse is centered at CurrentPoint.
• Steps controls the number of polygonal segments generated around the ellipse perimeter (defaulting to DefaultCircleSteps).

Calling Ellipse automatically starts a new closed sub-path.

Example

var
  Canvas: TCanvas32;
begin
  Canvas := TCanvas32.Create(MyBitmap);
  try
    // Draw an ellipse centered at (100, 100) with Rx=80, Ry=40
    Canvas.Ellipse(100.0, 100.0, 80.0, 40.0);
  finally
    Canvas.Free;
  end;
end;
