The Graphics::DrawPie method draws a pie.

Syntax

Status DrawPie(
  [in]       const Pen *pen,
  [in, ref]  const RectF &rect,
  [in]       REAL startAngle,
  [in]       REAL sweepAngle
);

Parameters

pen [in]
Type: const Pen*

Pointer to a pen that is used to draw the pie.
rect [in, ref]
Type: const RectF

Rectangle that bounds the ellipse in which to draw the pie.
startAngle [in]
Type: REAL

Real number that specifies the angle, in degrees, between the x-axis and the starting point of the arc that defines the pie. A positive value specifies clockwise rotation.
sweepAngle [in]
Type: REAL

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

Return value

Type:

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

The following illustration shows the pie that is drawn in the ellipse that is bounded by the rectangle. The illustration also shows the horizontal axis of the ellipse and the direction of the startAngle and the sweepAngle.

Examples

The following example draws a pie.

VOID Example_DrawPie2(HDC hdc)
{
   Graphics graphics(hdc);

   // Create a Pen object.
   Pen blackPen(Color(255, 0, 0, 0), 3);

   // Define the pie.
   RectF ellipseRect(0, 0, 200, 100);
   REAL startAngle = 0.0f;
   REAL sweepAngle = 45.0f;

   // Draw the pie.
   graphics.DrawPie(&blackPen, ellipseRect, startAngle, sweepAngle);
}
