Pie function (wingdi.h)
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.
Syntax
BOOL Pie(
[in] HDC hdc,
[in] int left,
[in] int top,
[in] int right,
[in] int bottom,
[in] int xr1,
[in] int yr1,
[in] int xr2,
[in] int yr2
);
Parameters
[in] hdc
A handle to the device context.
[in] left
The x-coordinate, in logical coordinates, of the upper-left corner of the bounding rectangle.
[in] top
The y-coordinate, in logical coordinates, of the upper-left corner of the bounding rectangle.
[in] right
The x-coordinate, in logical coordinates, of the lower-right corner of the bounding rectangle.
[in] bottom
The y-coordinate, in logical coordinates, of the lower-right corner of the bounding rectangle.
[in] xr1
The x-coordinate, in logical coordinates, of the endpoint of the first radial.
[in] yr1
The y-coordinate, in logical coordinates, of the endpoint of the first radial.
[in] xr2
The x-coordinate, in logical coordinates, of the endpoint of the second radial.
[in] yr2
The y-coordinate, in logical coordinates, of the endpoint of the second radial.
Return value
If the function succeeds, the return value is nonzero.
If the function fails, the return value is zero.
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.
The current position is neither used nor updated by the Pie function.
