MFC画标尺

void CJjjView::OnPaint()
{
    CPaintDC dc(this);

    //屏幕初始化
    dc.SetMapMode(MM_LOENGLISH);//0.01in  ;1英寸映射
    dc.SetTextAlign(TA_CENTER|TA_BOTTOM);
    dc.SetBkMode(TRANSPARENT);

    //画尺子主题
    CBrush brush(RGB(,,));
    CBrush* pOldBrush=dc.SelectObject(&brush);
    dc.Rectangle(,-,,-);
    dc.SelectObject(pOldBrush);

    //画刻度
    for(int i=;i<;i+=){
        dc.MoveTo(i,-);
        dc.LineTo(i,-);
    }
    for(i=;i<;i+=){
        dc.MoveTo(i,-);
        dc.LineTo(i,-);
    }
    for(i=;i<;i+=){
        dc.MoveTo(i,-);
        dc.LineTo(i,-);

        CString string;
        string.Format(_T("%d"),(i/)-);
        dc.TextOutA(i,-,string);
    }

    //商标

    //CRect rect(125,-125,175,-150);
    //CString string=_T("晨光");
    //dc.DrawText(string,&rect,DT_SINGLELINE|DT_CENTER|DT_VCENTER);
    dc.SetTextColor(RGB(,,));
    dc.TextOutA(,-,"晨光");
}

没想到画标尺这么简单，另外这位小兄弟的博客比较有用，简直是后生可畏：
