在VC++中实现渐变字

        // 更改当前字体
        LOGFONT lf;
        pDC->GetCurrentFont()->GetLogFont(&lf);
        CFont font, *pOldFont;
        lf.lfCharSet=134;
        lf.lfHeight=-150;
        lf.lfWidth=0;
        strcpy(lf.lfFaceName, "隶书");
        font.CreateFontIndirect(&lf);
        pOldFont=pDC->SelectObject(&font);
        pDC->SetBkMode(TRANSPARENT);
        // 更改当前画笔为空
        CPen pen(PS_NULL, 1, RGB(255, 0, 0)), *pOldPen;
        pOldPen=pDC->SelectObject(&pen);
        // 更改当前刷子
        CBrush br, *pOldBrush;
        pOldBrush=pDC->SelectObject(&br);
        // 开始一个路径
        pDC->BeginPath();
        pDC->TextOut(10, 10, "渐变字");
        pDC->EndPath();
        // 绘制渐变效果
        pDC->SelectClipPath(RGN_COPY);
        for (int i=255; i>0; i--)
        {
            int iRadius=(600*i)/255;
            pDC->SelectObject(pOldBrush);
            br.DeleteObject();
            br.CreateSolidBrush(RGB(255, i, 0));
            pDC->SelectObject(br);
            pDC->Ellipse(-iRadius, -iRadius/3, iRadius, iRadius/3);
        }
        // 恢复设备上下文的原有设置　
        pDC->SelectObject(pOldFont);
        pDC->SelectObject(pOldPen);
        pDC->SelectObject(pOldBrush);
