Pie

The Pie function draws a pie-shaped wedge bounded by the intersection of an ellipse and two radials. The pie is outlined by using the current pen and filled by using the current brush.

BOOL Pie(
  HDC hdc,         // handle to device context
  int nLeftRect,   // x-coord of bounding rectangle's upper-left corner
  int nTopRect,    // y-coord of bounding rectangle's upper-left corner
  int nRightRect,  // x-coord of bounding rectangle's lower-right corner
  int nBottomRect, // y-coord of bounding rectangle's lower-right corner
  int nXRadial1,   // x-coord of first radial's endpoint
  int nYRadial1,   // y-coord of first radial's endpoint
  int nXRadial2,   // x-coord of second radial's endpoint
  int nYRadial2    // y-coord of second radial's endpoint
);
 

Parameters

hdc
Handle to the device context.
nLeftRect
Specifies the x-coordinate of the upper-left corner of the bounding rectangle.
nTopRect
Specifies the y-coordinate of the upper-left corner of the bounding rectangle.
nRightRect
Specifies the x-coordinate of the lower-right corner of the bounding rectangle.
nBottomRect
Specifies the y-coordinate of the lower-right corner of the bounding rectangle.
nXRadial1
Specifies the x-coordinate of the endpoint of the first radial.
nYRadial1
Specifies the y-coordinate of the endpoint of the first radial.
nXRadial2
Specifies the x-coordinate of the endpoint of the second radial.
nYRadial2
Specifies the y-coordinate of the endpoint of the second radial.

Return Values

If the function succeeds, the return value is nonzero.

If the function fails, the return value is zero.

Windows NT: To get extended error information, call GetLastError.

Remarks

The curve of the pie is defined by an ellipse that fits the specified bounding rectangle. The curve begins at the point where the ellipse intersects the first radial and extends counterclockwise to the point where the ellipse intersects the second radial. (A radial is a line drawn from the center of the ellipse to the specified endpoint on the ellipse.)

The current position is neither used nor updated by the Pie function.

Windows 95 and Windows 98: The sum of the coordinates of the bounding rectangle cannot exceed 32,767. The sum of nLeftRect and nRightRect or nTopRect and nBottomRect parameters cannot exceed 32,767.
