1. stdafx.h에 추가
#include <gdiplus.h>
using namespace Gdiplus;
#pragma comment(lib, "gdiplus.lib")

2. 초기화, 닫기
        GdiplusStartupInput gdiplusStartupInput;
        ULONG_PTR           gdiplusToken;
    - InitInstance()에서 초기화   
        GdiplusStartup(&gdiplusToken, &gdiplusStartupInput, NULL);
    - ExitInstance()에서 닫기
        GdiplusShutdown(gdiplusToken);

3. 그리기
void CGdiPlusView::OnDraw(CDC* pDC)
{
...
    Graphics graphics(pDC->m_hDC);
    LinearGradientBrush linGrBrush(Point(0, 10),
                                   Point(200, 10),
                                   Color(255, 255, 0, 0),   // opaque red
                                   Color(255, 0, 0, 255));  // opaque blue

    Pen pen(&linGrBrush);
    graphics.DrawLine(&pen, 0, 10, 200, 10);
    graphics.FillEllipse(&linGrBrush, 0, 30, 200, 100);
    graphics.FillRectangle(&linGrBrush, 0, 155, 500, 30);
