Graphics graphics(hdc);
Point points[] = {
Point(110, 20),
Point(120, 30),
Point(100, 60),
Point(120, 70),
Point(150, 60),
Point(140, 10)};
Rect rect(65, 15, 70, 45);
GraphicsPath path;
SolidBrush solidBrush(Color(255, 255, 0, 0));
path.AddClosedCurve(points, 6);
// Create a region from a path.
Region pathRegion(&path);
// Create a region from a rectangle.
Region rectRegion(rect);
// Update the region to the portion that intersects with another region.
pathRegion.Intersect(&rectRegion);
graphics.FillRegion(&solidBrush, &pathRegion);
}
