The Graphics::DrawPie method draws a pie.

Syntax

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

Parameters

pen

Pointer to a pen that is used to draw the pie.

rect

Rectangle that bounds the ellipse in which to draw the pie.

startAngle

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

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

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 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);
}
