This method creates an elliptical pie-shaped path between angles.

Syntax

HRESULT DrawAnglePie (
FLOAT left,
FLOAT top,
FLOAT right,
FLOAT bottom,
FLOAT degreeStartAngle,
FLOAT degreeSweepAngle
)
Parameters
left
X coordinate of the top-left corner of the bounding rectangle

top
Y coordinate of the top-left corner of the bounding rectangle

right
X coordinate of the bottom-right corner of the bounding rectangle

bottom
Y coordinate of the bottom-right corner of the bounding rectangle.

degreeStartAngle
Start angle

degreeSweepAngle
Sweep angle

Return value
If successful, this method returns S_OK. If it fails, this method should return one of the error values.

Remarks

This method draws a path as a part of an ellipse whose center is a point (centerX, centerY) and radius defined by the pair (radiusX, radiusY). The pie is drawn following the perimeter of the ellipse, counterclockwise, from the starting point to the sweeping angle degreeSweepAngle. The starting point is defined by the intersection of the ellipse and a line drawn by the angle degreeStartAngle. Both angles are measured in degrees.
