<title>WEB打印控件LODOP的样例八:打印网页图片</title>
<script language="javascript" src="LodopFuncs.js"></script>
</head>
<body>

<h2><b><font color="#009999">演示打印网页图片：</font></b></h2>
<p>利用<font color="#0000FF">ADD_PRINT_IMAGE和SET_PRINT_STYLEA</font>函数可以缩放打印图片，用IMG标签打印WEB图片，用全路径打印本地图片。 </p>

<p>下面是互联网上的一个图片： </p>

<img border="0" src="http://www.lodop.net/demolist/PrintSample8.jpg" width=345 height=250 />&nbsp;

<p>1：看到图片了吗（没有联网可能看不到哟）？如果能看到就可以打印出来，</p>

<p>&nbsp;先<a href="javascript:myPreview1()">打印预览1</a>，感觉满意可<a href="javascript:myPrint1()">直接打印</a>  
 ，如不满意可用<a href="javascript:myPrintSetup1()">打印维护</a>调整。</p>     

<p>&nbsp;这种（默认）方式为截取模式，即当设定区域小于实际图时会截掉剩余的。</p>

<p>下面演示另外两种模式：</p>

<p>2：(可变形)扩展缩放模式，放大成600px×250px看看<a href="javascript:myPreview2();">打印预览2</a>。</p>

<p>3：按原图比例（不变形）缩放打印模式，看看<a href="javascript:myPreview3();">打印预览3</a>。</p>

<p>4：打印透明图片见<a href="javascript:myPreview4();">打印预览4</a>或公章请参考<a href="PrintSample37.html">样例37</a>。
</p>

<p>5：用BASE64编码图片请参考<a href="PrintSample38.html">样例38</a>。
