Pie info Overview Group

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: Identifies 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. 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: 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.
