<h2><font color="#009999">演示如何打印条形码：</font>
</h2>
<p>Lodop绘制条码图功能让条码打印变得很简单，客户端不用安装专门的条码字库，该函数格式如下：<span LANG="ZH"><font color="#0000FF" size="3"><br>
ADD_PRINT_BARCODE(Top,Left,Width,Height,BarCodeType,BarCodeValue);</font></span></p>
<p>关键参数含义:</p>
<p><span LANG="ZH"><font color="#0000FF" size="3">Width</font></span><font color="#0000FF"> </font><font color="#000000">条码的总宽度，计量单位px（1px=1/96英寸）<br>
</font><span LANG="ZH"><font color="#0000FF" size="3">Height</font></span><font color="#0000FF"> </font><font color="#000000">条码的总高度（一维条码时包括文字高度）</font><span LANG="ZH"><font color="#0000FF" size="3"><br>
BarCodeType</font></span> 条码的类型（规制）名称<span LANG="ZH"><font color="#0000FF" size="3"><br>
BarCodeValue</font></span><font color="#0000FF"> </font><font color="#000000">条码值</font></p>
<p><font size="3">目前控件支持的条码类型有如下26种，包含24种一维码和2种二维码：

<p><b>一、演示各种条码</b></p>
<p>看看演示：<input type="button" value="打印预览" name="B3" onclick="prn_Preview()">
<input type="button" value="打印设计" name="B3" onclick="prn_Design()"></p>
<p>注意：打印设计中改变对象区域大小时，条码会自动随之适应调整，也可以360度范围随便定义旋转方向。</p>
<p>双击对象，在弹出的属性窗口中修改其它属性，然后生成程序代码看看其实现方法。</p>
<p><b>二、内嵌显示条码(及其它图形对象)</b></p>
1:先点击<a href="javascript:myShow1()">显示条码</a>在如下区域直接绘制一个条码：
<br>2:再进入<a href="javascript:myShow2()">打印设计</a>加几个图类对象(图表、条码、图形图线、图片)，用其程序代码绘制如下：<br>
