Visual C++ MFC绘制熊猫吉祥物的代码

以下是一个基于 MFC 的绘制熊猫吉祥物的示例代码：

void CPandaView::OnDraw(CDC* pDC)
{
    CPandaDoc* pDoc = GetDocument();
    ASSERT_VALID(pDoc);
    if (!pDoc)
        return;

    // 获取绘图区域的宽度和高度
    CRect rect;
    GetClientRect(&rect);
    int nWidth = rect.Width();
    int nHeight = rect.Height();

    // 计算熊猫头部的位置和大小
    int nHeadX = nWidth / 2;
    int nHeadY = nHeight / 3;
    int nHeadSize = nHeight / 3;

    // 绘制熊猫头部
    CPen pen(PS_SOLID, 3, RGB(0, 0, 0));
    CBrush brush(RGB(255, 255, 255));
    CPen* pOldPen = pDC->SelectObject(&pen);
    CBrush* pOldBrush = pDC->SelectObject(&brush);
    pDC->Ellipse(nHeadX - nHeadSize, nHeadY - nHeadSize, nHeadX + nHeadSize, nHeadY + nHeadSize);

    // 计算熊猫眼睛的位置和大小
    int nEyeSize = nHeadSize / 4;
    int nLeftEyeX = nHeadX - nHeadSize / 2 + nEyeSize * 2;
    int nRightEyeX = nHeadX + nHeadSize / 2 - nEyeSize * 2;
    int nEyeY = nHeadY - nHeadSize / 4;

    // 绘制熊猫眼睛
    CBrush blackBrush(RGB(0, 0, 0));
    CBrush* pOldBrush2 = pDC->SelectObject(&blackBrush);
    pDC->Ellipse(nLeftEyeX - nEyeSize, nEyeY - nEyeSize, nLeftEyeX + nEyeSize, nEyeY + nEyeSize);
    pDC->Ellipse(nRightEyeX - nEyeSize, nEyeY - nEyeSize, nRightEyeX + nEyeSize, nEyeY + nEyeSize);

    // 绘制熊猫鼻子
    CBrush redBrush(RGB(255, 0, 0));
    CBrush* pOldBrush3 = pDC->SelectObject(&redBrush);
    pDC->Ellipse(nHeadX - nEyeSize, nHeadY, nHeadX + nEyeSize, nHeadY + nEyeSize);

    // 绘制熊猫嘴巴
    CPen pen2(PS_SOLID, 2, RGB(0, 0, 0));
    CPen* pOldPen2 = pDC->SelectObject(&pen2);
    pDC->Arc(nHeadX - nHeadSize / 2, nHeadY, nHeadX + nHeadSize / 2, nHeadY + nHeadSize / 2, nHeadX - nHeadSize / 2, nHeadY, nHeadX + nHeadSize / 2, nHeadY);

    // 绘制熊猫耳朵
    CPoint pt[3];
    pt[0] = CPoint(nHeadX - nHeadSize / 2, nHeadY - nHeadSize / 2);
    pt[1] = CPoint(nHeadX - nHeadSize / 4, nHeadY - nHeadSize * 3 / 4);
    pt[2] = CPoint(nHeadX + nHeadSize / 4, nHeadY - nHeadSize / 2);
    pDC->Polygon(pt, 3);
    pt[0] = CPoint(nHeadX + nHeadSize / 2, nHeadY - nHeadSize / 2);
    pt[1] = CPoint(nHeadX + nHeadSize / 4, nHeadY - nHeadSize * 3 / 4);
    pt[2] = CPoint(nHeadX - nHeadSize / 4, nHeadY - nHeadSize / 2);
    pDC->Polygon(pt, 3);

    // 恢复画笔和画刷
    pDC->SelectObject(pOldPen);
    pDC->SelectObject(pOldBrush);
    pDC->SelectObject(pOldBrush2);
    pDC->SelectObject(pOldBrush3);
    pDC->SelectObject(pOldPen2);
}

在上述代码中，我们使用了 MFC 的绘图函数，如 `SelectObject`、`Ellipse`、`Polygon` 等，来绘制熊猫的各个部分。通过计算各个部分的位置和大小，我们可以将熊猫绘制在绘图区域的中央。
