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.
