Graphics.DrawPolygon(const Pen*, const PointF*, INT*) method
Applies to: desktop apps only
The Graphics::DrawPolygon method draws a polygon.
Syntax
Status DrawPolygon(
[in] const Pen *pen,
[in] const PointF *points,
[in] INT *count
);
Parameters
pen [in]
Type: const Pen*Pointer to a pen that is used to draw the polygon.
points [in]
Type: const PointF*Pointer to an array of PointF objects that specify the vertices of the polygon.
count [in]
Type: INT*Integer that specifies the number of elements in the points array.
Return value
Type:
Type: Status****
If the method succeeds, it returns Ok, which is an element of the Status enumeration.
If the method fails, it returns one of the other elements of the Status enumeration.
Remarks
If the first and last coordinates in the points array are not identical, a line is drawn between them to close the polygon.
Examples
The following example draws a polygon, defined by an array of points.
VOID Example_DrawPolygon2(HDC hdc)
{
Graphics graphics(hdc);
// Create a Pen object.
Pen blackPen(Color(255, 0, 0, 0), 3);
// 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, 200.0f);
PointF point4(50.0f, 200.0f);
PointF point5(0.0f, 130.0f);
PointF points[5] = {point1, point2, point3, point4, point5};
PointF* pPoints = points;
// Draw the polygon.
graphics.DrawPolygon(&blackPen, pPoints, 5);
}
