The following example defines a polygon and fills it.
C++
VOID Example_FillPolygon4(HDC hdc)
{
Graphics graphics(hdc);
// Create a SolidBrush object.
SolidBrush blackBrush(Color(255, 0, 0, 0));
// Create an array of PointF objects that define the polygon.
PointF point1(100.0f, 100.0f);
PointF point2(200.0f, 130.0f);
PointF point3(150.0f, 200.0);
PointF point4(50.0f, 200.0f);
PointF point5(0.0f, 130.0f);
PointF points[5] = {point1, point2, point3, point4, point5};
// Fill the polygon.
graphics.FillPolygon(&blackBrush, points, 5, FillModeAlternate);
}
