Draw a polygon
#include <GDIPlus.au3>
_GDIPlus_GraphicsDrawPolygon ( $hGraphics, $aPoints [, $hPen = 0] )
| $hGraphics | Handle to a Graphics object |
| $aPoints | Array that specify the vertices of the polygon: [0][0] - Number of vertices [1][0] - Vertice 1 X position [1][1] - Vertice 1 Y position [2][0] - Vertice 2 X position [2][1] - Vertice 2 Y position [n][0] - Vertice n X position [n][1] - Vertice n Y position |
| $hPen | [optional] Handle to a pen object that is used to draw the polygon. If 0, a solid black pen with a width of 1 will be used. |
| Success: | True. |
| Failure: | False and sets the @error flag to non-zero, @extended may contain GPSTATUS error code ($GPIP_ERR* see GPIPlusConstants.au3). |
If the first and last points are not identical, a line is drawn between them to close the polygon.
