Transforms and flattens a path, and then converts the path's data points so that they represent only the outline of the path
#include <GDIPlus.au3>
_GDIPlus_PathWindingModeOutline ( $hPath [, $hMatrix = 0 [, $fFlatness = 0.25]] )
| $hPath | Pointer to a GraphicsPath object |
| $hMatrix | [optional] Pointer to a Matrix object that specifies the transformation. If 0, no transformation is applied |
| $fFlatness | [optional] Real number that specifies the maximum error between the path and its flattened approximation. Reducing the flatness increases the number of line segments in the approximation. |
| Success: | True. |
| Failure: | False and sets the @error flag to non-zero, @extended may contain GPSTATUS error code ($GPIP_ERR* see GPIPlusConstants.au3). |
