GDI+ 图像平铺

最近在做表格,需要用的图片的平铺

就上网找点了资料

做了下整理

方法1.

　　 HDC hdc=GetDC(m_HWND);
　   Gdiplus::Image* pImage=Gdiplus::Image::FromFile(L"gridhead.png",true);
    Gdiplus:: Graphics graphics(hdc);
    Gdiplus:: ImageAttributes ImgAtt;
    ImgAtt.SetWrapMode(Gdiplus:: WrapModeTileFlipXY);
    Gdiplus:: RectF rcDrawRect;//目标图像的RECT
    rcDrawRect.X=0;
    rcDrawRect.Y=0;
    rcDrawRect.Width=100;
    rcDrawRect.Height=30;
    graphics.DrawImage(pImage,rcDrawRect,0,0,1,30,Gdiplus:: UnitPixel,&ImgAtt);
    ReleaseDC(m_HWND,hdc);

方法2.

　　Gdiplus::Image* pImage=Gdiplus::Image::FromFile(L"gridhead.png",true);
　　TextureBrush headbrush(pImage, WrapModeTile );
　　graphics.FillRectangle(&headbrush, RectF(0, 0,100,30));
