Adds an elliptical arc to the current figure of a path
#include <GDIPlus.au3>
_GDIPlus_PathAddArc ( $hPath, $nX, $nY, $nWidth, $nHeight, $fStartAngle, $fSweepAngle )
| $hPath | Pointer to a GraphicsPath object |
| $nX | X coordinate of the upper-left corner of the ellipse that contains the arc |
| $nY | Y coordinate of the upper-left corner of the ellipse that contains the arc |
| $nWidth | Width of the bounding rectangle for the ellipse that contains the arc |
| $nHeight | Height of the bounding rectangle for the ellipse that contains the arc |
| $fStartAngle | The angle, in degrees, between the X axis and the starting point of the arc |
| $fSweepAngle | The angle, in degrees, between the starting and ending points of the arc |
| Success: | True. |
| Failure: | False and sets the @error flag to non-zero, @extended may contain GPSTATUS error code ($GPIP_ERR* see GPIPlusConstants.au3). |
