Creates a region that is defined by a rectangle
#include <GDIPlus.au3>
_GDIPlus_RegionCreateFromRect ( $nX, $nY, $nWidth, $nHeight )
| $nX | The X coordinate of the upper left corner of the rectangle |
| $nY | The Y coordinate of the upper left corner of the rectangle |
| $nWidth | The width of the rectangle |
| $nHeight | The height of the rectangle |
| Success: | a handle to a new Region object. |
| Failure: | 0 and sets the @error flag to non-zero, @extended may contain GPSTATUS error code ($GPIP_ERR* see GPIPlusConstants.au3). |
After you are done with the object, call _GDIPlus_RegionDispose() to release the object resources.
