Gets the next marker-delimited section of an iterator's associated path
#include <GDIPlus.au3>
_GDIPlus_PathIterNextMarkerPath ( $hPathIter, $hPath )
| $hPathIter | Pointer to a GraphicsPathIterator object |
| $hPath | Pointer to a GraphicsPath object |
| Success: | the number of point in the retrieved section or 0 if no more sections to be retrieved |
| Failure: | -1 and sets the @error flag to non-zero, @extended may contains GPSTATUS error code ($GDIP_ERR* see GDIPlusConstants.au3). |
This function sets the data points of the specified GraphicsPath object to match the data points of the retrieved section.
