GraphicsPath::AddPie(constRectF&,REAL,REAL) method (gdipluspath.h)

Article
02/22/2024

The GraphicsPath::AddPie method adds a pie to this path. An arc is a portion of an ellipse, and a pie is a portion of the area enclosed by an ellipse. A pie is bounded by an arc and two lines (edges) that go from the center of the ellipse to the endpoints of the arc.

Syntax

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

Parameters

rect

Reference to a rectangle that bounds the ellipse that bounds the pie.

startAngle

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

sweepAngle

Real number that specifies the clockwise angle, in degrees, between the starting and ending points of the arc that defines the pie.

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 a pie to path, and then draws path.

VOID Example_AddPie(HDC hdc)
{
   Graphics graphics(hdc); 

   RectF rect(50.0f, 50.0f, 100.0f, 100.0f);

   GraphicsPath path;
   path.AddPie(rect, 20.0f, 45.0f);

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

   graphics.DrawPath(&pen, &path);
}
