用gdi +和点向量绘制多边形

Question

我有一个PointF's的向量，我试图用GDI +绘制一个多边形：

void Polygons::create_polygons(CDC& dc, std::array<Gdiplus::Color, 6>& cols)
{
    Gdiplus::Graphics gr{ dc };
    find_poly_vertices();
    Gdiplus::Pen pen{ Gdiplus::Color(255,0,0,0) };
    auto old_brush = dc.GetCurrentBrush();
    for (int i = 0; i != points.size(); ++i)
    {

        Gdiplus::SolidBrush br{ cols[i] };
        gr.DrawPolygon(&pen, points[i], points[i].size());
        gr.FillPolygon(&br, points[i], points[i].size());
    }
    dc.SelectObject(old_brush);
}

find_poly_vertices（）将多边形的点保存在Polygons中的向量数组中。

在Visual Studio中编译时，出现错误C2664：

cannot convert argument 2 from"std::vector<Gdiplus::PointF,std::allocator<_Ty>>" to "const Gdiplus::PointF *"
