         <i>nPitchAndFamily</i> 字体间的间距<br>
        <i>lpszFacename</i> 指定字体名称，为了得到系统所拥有的字体可以利用EmunFontFamiliesEx。（可以参考文章<a 
            href="../../vchelp.163.net/refer/gb_big5_dis.htm" 
            target=_blank>在同一系统中显示GB字符和BIG5字符</a>）<br>

        <p></p>
        <p class="unnamed1"> 此外可以利用CFontDialog来得到用户选择的字体的LOGFONT数据。</span></p>
        <p class="unnamed1"> 最后我讲一下文本坐标的计算，利用CDC::GetTextExtent( 
          const CString&amp; str )可以得到字符串的在输出时所占用的宽度和高度，这样就可以在手工输出多行文字时使用正确的行距。另外如果需要更精确的对字体高度和宽度进行计算就需要使用CDC::GetTextMetrics( 
          LPTEXTMETRIC lpMetrics ) 该函数将会填充TEXTMETRIC结构，该结构中的分量可以非常精确的描述字体的各种属性。</span></p>
