c++ - 如何填充贝塞尔曲线gdi c

Question

我需要用颜色填充闭合贝塞尔曲线...任何人都可以帮助我改进此代码，因为它不起作用:

    COLORREF collor = RGB(100,50,150);
    CPen g(PS_INSIDEFRAME, 50, collor);
    pDC->SetBkColor(RGB(90, 100, 128));
    pDC->SelectObject(&g);
    CPoint Pt[10]=
{ 

    CPoint(400, 260),
    CPoint(480, 260),
    CPoint(500, 260),
    CPoint(470, 290),
    CPoint(450, 350),
    CPoint(470, 370),
    CPoint(430, 370),
    CPoint(420, 391),
    CPoint(405, 410),
    CPoint(400, 260),
};
    pDC->PolyBezier(Pt, 10);

谢谢!

您需要选择一个已创建为纯色且具有您想要填充的颜色的画笔。

CBrush brush;
brush.CreateSolidBrush(collor);
CBrush * pOldBrush = (CBrush *) pDC->SelectObject(&brush);
...
pDC->SelectObject(pOldBrush);
