MFC中CDC相关图形，文本的一些使用方法（转）

    CPen* PenOld,PenNew;
    CBrush* BrushOld,BrushNew;

    //选用库存黑色画笔
    PenOld = (CPen*)pDC->SelectStockObject(BLACK_PEN);

    //选用库存浅灰色画刷
    BrushOld = (CBrush*)pDC->SelectStockObject(LTGRAY_BRUSH);
    pDC->Rectangle(100,100,300,300);

    //关联GDI 库存对象
    PenNew.CreateStockObject(WHITE_PEN);
    pDC->SelectObject(&PenNew);
    pDC->MoveTo(100,100);
    pDC->LineTo(300,300);
    pDC->MoveTo(100,300);
    pDC->LineTo(300,100);

    //恢复系统默认的GDI对象
    pDC->SelectObject(PenOld);
    pDC->SelectObject(BrushOld);

    PenNew.DeleteObject();

    //创建有一个实心的画刷
    CBrush* brush = new CBrush;
    brush->CreateSolidBrush(RGB(255,0,0));
    pDC->SelectObject(brush);
    pDC->Rectangle(400,400,500,500);

    //创建阴影画刷
    CBrush BrushOl;
    BrushOl.CreateHatchBrush(HS_BDIAGONAL,RGB(0,0,255));
    pDC->SelectObject(&BrushOl);
    pDC->Rectangle(200,400,300,500);

    //创建位图刷函数
    CBrush BrushBit;
    CBitmap Bitmap;
    Bitmap.LoadBitmap(IDB_BITMAP1);
    BrushBit.CreatePatternBrush(&Bitmap);
    pDC->SelectObject(&BrushBit);
    pDC->Rectangle(0,0,100,100);

    //设置文本背景
    pDC->SetBkColor(RGB(0,255,0));//背景颜色
    pDC->SetBkMode(OPAQUE);//背景模式
    pDC->SetTextAlign(TA_LEFT|TA_BOTTOM);//设置文本对齐方式
    pDC->TextOut(0,100,"哈哈~~~//设置文本背景~~~");

    //设置文本字体
    CFont font;
    VERIFY(font.CreatePointFont(200, "黑体", pDC));
    pDC->SelectObject(&font);
    pDC->TextOut(400,300,"哈哈~~~//设置文本字体~~~");

    //使用CBitmap类,显示位图
    CBitmap* pBitmap = new CBitmap;
    pBitmap->LoadBitmap(IDB_BITMAP2);//将位图装入内存
    CDC MemDc;
    MemDc.CreateCompatibleDC(pDC);//创建内存设备环境
    //将位图对象选入设备环境中,并保存原来设备环境的指针
    CBitmap* pBitmapOld = MemDc.SelectObject(pBitmap);
    BITMAP stBitmap;
    pBitmap->GetBitmap(&stBitmap);//获取位图信息
    //输出位图函数: 把源设备环境中的位图复制到目标设备环境中//显示位图
    pDC->BitBlt(70,70,stBitmap.bmWidth,stBitmap.bmHeight,&MemDc,0,0,SRCCOPY);
    pDC->SelectObject(pBitmapOld); //恢复设备环境

最近做的项目与MFC的图像方面比较有联系，所以搜藏下
