The Graphics::DrawArc method draws an arc. The arc is part of an ellipse.

Syntax

Status DrawArc(
  [in]  const Pen *pen,
  [in]  REAL x,
  [in]  REAL y,
  [in]  REAL width,
  [in]  REAL height,
  [in]  REAL startAngle,
  [in]  REAL sweepAngle
);

Parameters

pen [in]
Type: const Pen*

Pointer to a pen that is used to draw the arc.
x [in]
Type: REAL

Real number that specifies the x-coordinate of the upper-left corner of the bounding rectangle for the ellipse that contains the arc.
y [in]
Type: REAL

Real number that specifies the y-coordinate of the upper-left corner of the bounding rectangle for the ellipse that contains the arc.
width [in]
Type: REAL

Real number that specifies the width of the ellipse that contains the arc.
height [in]
Type: REAL

Real number that specifies the height of the ellipse that contains the arc.
startAngle [in]
Type: REAL

Real number that specifies the angle between the x-axis and the starting point of the arc.
sweepAngle [in]
Type: REAL

Real number that specifies the angle between the starting and ending points of the arc.

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.

Examples

The following example draws a 90-degree arc.

VOID Example_DrawArc4(HDC hdc)
{
   Graphics graphics(hdc);

   // Set up the arc.
   Pen redPen(Color(255, 255, 0, 0), 3);
   REAL x = 0;
   REAL y = 0;
   REAL width = 200.0f;
   REAL height = 100.0f;
   REAL startAngle = 0.0f;
   REAL sweepAngle = 90.0f;

   // Draw the arc.
   graphics.DrawArc(&redPen, x, y, width, height, startAngle, sweepAngle);
}
