GraphicsPath::AddArc method

The GraphicsPath::AddArc method adds an elliptical arc to the current figure of this path.

Syntax

Status AddArc(
  IN const RectF & rect,
  IN REAL          startAngle,
  IN REAL          sweepAngle
);

Parameters

rect

Reference to a rectangle that bounds the ellipse that contains the arc.

startAngle

Real number that specifies the clockwise angle, in degrees, between the horizontal axis of the ellipse and the starting point of the arc.

sweepAngle

Real number that specifies the clockwise angle, in degrees, between the starting point (startAngle) and the ending point of the arc.

Return Value

Type: Status

If the method succeeds, it returns Ok, which is an element of the Status enumeration.

If the method fails, it returns one of the other elements of the Status enumeration.

Remarks

Examples

The following example creates a GraphicsPath object path, adds an arc to path, closes the arc, and then draws path.

VOID AddArcExample(HDC hdc)
{
   Graphics graphics(hdc);
   RectF rect(20.0f, 20.0f, 50.0f, 100.0f);

   GraphicsPath path;
   path.AddArc(rect, 0.0f, 180.0f);
   path.CloseFigure();

   // Draw the path.
   Pen pen(Color(255, 255, 0, 0));
   graphics.DrawPath(&pen, &path);
}
