MFC和GDI+一起使用

VS2010，新建MFC项目，在头文件stdafx.h中添加：

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

定义类的变量 ULONG_PTR   gdiplusToken;

在BOOL CGDALDesktopApp::InitInstance()中添加：

 GdiplusStartupInput gdiplusStartupInput;
2 GdiplusStartup(&gdiplusToken, &gdiplusStartupInput, NULL);

在ExitInstance()中添加：

 int CGDALDesktopApp::ExitInstance()
 {
     //TODO: 处理可能已添加的附加资源
     AfxOleTerm(FALSE);
      GdiplusShutdown(gdiplusToken);
     return CWinAppEx::ExitInstance();
 }

添加绘制的代码：

 void CGDALDesktopView::OnDraw(CDC* pDC)
 {
     CGDALDesktopDoc* pDoc = GetDocument();
     ASSERT_VALID(pDoc);
     if (!pDoc)
         return;
 
     //Graphics graphics(*pDC);
         Graphics g( pDC->GetSafeHdc() );
     //建立画笔
      Pen pen_black(Color::Black);
      Pen pen_white(Color::White);
     //使用画笔绘制图形
     pen_black.SetWidth(); //设置画笔宽度
     pen_black.SetStartCap(LineCapRoundAnchor); //设置开始笔帽
     pen_black.SetEndCap(LineCapArrowAnchor); //设置结束笔帽
     g.DrawLine(&pen_black, , , , );
     Rect rect1(,, , );
     Rect rect2( + , , , );
     Rect rect3( + *, , , );
     Rect rect4( + *, , , );
     g.DrawRectangle(&pen_black, rect1);
      g.DrawRectangle(&pen_black, rect2);
      g.DrawRectangle(&pen_black, rect3);
      g.DrawRectangle(&pen_black, rect4);
     //建立画刷
      //实色画刷
     SolidBrush brush_black(Color::Black);
      SolidBrush brush_white(Color::White);
      SolidBrush brush_blue(Color::Blue);
      g.FillRectangle(&brush_blue, rect1);
      //网格画刷
      HatchBrush brush_hatch( HatchStyleDiagonalBrick, Color(, , , ), Color(, , , ));
     g.FillRectangle(&brush_hatch, rect2);
      //贴图画刷
      Image image(L"res\\qq.gif");
      TextureBrush brush_texture(&image);
      g.FillRectangle(&brush_texture, rect3);
      //渐变画刷(线形渐变)
      LinearGradientBrush brush_gradient_line( Point(, ), Point(, ),Color(, , , ), Color(, , , ));
      g.FillRectangle(&brush_gradient_line, rect4);
      //渐变画刷(路径渐变)
      //PathGradientBrush......................
     //贴图画笔
      Pen pen_texture(&brush_texture, );
     g.DrawEllipse(&pen_texture, , ,  ,);
     //启动抗锯齿功能
      pen_black.SetWidth();
      g.SetSmoothingMode(SmoothingModeAntiAlias);
      g.DrawLine(&pen_black, , ,  , );
     //绘制图像
     // 不进行缩放
      g.DrawImage(&image, ,);
      // 使用低质量的插补算法
      g.SetInterpolationMode(InterpolationModeNearestNeighbor);
      g.DrawImage( &image, Rect(,, , ));
      // 使用中等质量的插补算法
      g.SetInterpolationMode(InterpolationModeHighQualityBilinear);
      g.DrawImage( &image, Rect(,, , ));
      // 使用高质量的插补算法
      g.SetInterpolationMode(InterpolationModeHighQualityBicubic);
      g.DrawImage( &image, Rect(,, , ));
     //路径
     GraphicsPath path1;
     path1.AddLine(, ,  ,);
     path1.AddArc(, , , , , -);
     g.DrawPath(&pen_black, &path1);
     g.FillPath(&brush_black, &path1);
     //区域
     GraphicsPath pathOuter;
     pathOuter.AddRectangle(Rect(, ,  ,));
     GraphicsPath pathInner;
      pathInner.AddEllipse(Rect(, ,  ,));
      Region rgn(&pathOuter);
      rgn.Exclude(&pathInner);
     g.FillRegion(&brush_blue, &rgn);
     // TODO: 在此处为本机数据添加绘制代码
