   Collapse AllThis method creates an elliptically curved path between angles.
|
| HRESULT PDFPAGE_Arc2 ( DOUBLE centerX, DOUBLE centerY, DOUBLE radiusX, DOUBLE radiusY, DOUBLE degreeStartAngle, DOUBLE degreeSweepAngle, DOUBLE* currentX, DOUBLE* currentY ) |
Parameters
centerX
X coordinate of the center of the ellipse center
centerY
Y coordinate of the center of the ellipse
radiusX
Horizontal radius of the ellipse.
radiusY
Vertical radius of the ellipse.
degreeStartAngle
Start angle of the arc.
degreeSweepAngle
Sweep angle of the arc.
currentX
X coordinate of the current point of the arc
currentY
Y coordinate of the current point 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 returns the current point position specified by the last two parameters.
