This method creates an elliptically curved path between angles.

Syntax

HRESULT DrawAngleArc (
FLOAT centerX,
FLOAT centerY,
FLOAT radiusX,
FLOAT radiusY,
FLOAT degreeStartAngle,
FLOAT degreeSweepAngle
)
Parameters
centerX
X coordinate of the ellipse center

centerY
Y coordinate of the ellipse center

radiusX
Horizontal radius of the ellipse

radiusY
Vertical radius of the ellipse

degreeStartAngle
Start angle of the arc.

degreeSweepAngle
Sweep angle of the arc.

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 arc 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. This method also draws a line from the current position to the starting point.
