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：

ADD_PRINT_BARCODE(Top,Left,Width,Height,BarCodeType,BarCodeValue);

关键参数含义:

Width 条码的总宽度，计量单位px（1px=1/96英寸）
Height 条码的总高度（一维条码时包括文字高度）
BarCodeType 条码的类型（规制）名称
BarCodeValue 条码值

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：

演示各种条码（条形码及二维码的生成）

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。

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。

示例代码：

<input type="button" value="打印预览" name="B3"  onclick="prn_Preview()"> 

function prn_Preview() {		
    CreatePrintPage();
    LODOP.PREVIEW();		
};

function CreatePrintPage() {
    LODOP=getLodop(document.getElementById('LODOP1'),document.getElementById('LODOP_EM1'));
