摘要 ：这几天遇到个需求，需要提供用户下载电子证照，最简单的方法实现:word做了一份模板，利用网页工具转成OFD文件,http://www.yozodcs.com/page/example.html用7Z工具解压ofd文件，压缩使用WinZip,压缩的时候不能带根路径;得到文件目录结构如下：
首先我们来看OFD文件的目录结构，OFD文件底层为XML，解析可查看相关文档，下面简述我了解的：
Doc_1文件夹下面是主要内容
Pages下面存放OFD每个页面的XML
简单说明Pages下面页面信息ＸＭＬ文件的标签及属性作用
<?xml version="1.0" encoding="UTF-8" standalone="yes"?>
<ofd:Page xmlns:ofd="http://www.ofdspec.org/2016">
<ofd:Area>
<ofd:PhysicalBox>0 0 209.90291 296.68628</ofd:PhysicalBox>
<ofd:ApplicationBox>0 0 209.90291 296.68628</ofd:ApplicationBox>
<ofd:ContentBox>0 0 209.90291 296.68628</ofd:ContentBox>

<ofd:TextObject ID="9" Font="8" Size="7.761115550994873" Boundary="47.2723 67.0278 261.0557 15.5222">

</ofd:CGTransform>
<ofd:TextCode X="0.0" Y="7.7611" DeltaX="7.7611 7.4083 7.4083 7.7611 7.7611 7.7611 7.7611 7.7611 7.7611 7.7611 7.7611 7.7611 8.1139 7.0556 7.7611 7.7611">填充字符填充字符填充字符填充字符填</ofd:TextCode>
</ofd:TextObject>
</ofd:Layer>
</ofd:Content>
</ofd:Page>
ofd:CGTransform：标签内的内容，为网站生成模板内，Res文件夹下的字体文件内的检索码，这里重点说明，我们通过网站得到的模板文件，在res文件加下面存放的字体文件只包含你OFD文件内存在的文字，所以你会发现这个字体文件特别小，你需要到你电脑的C:\Windows\Fonts下面找到你需要的字体文件，或者自己准备也行，这样可以保证OFD文件在各种环境下查看，打印字体的统一！！！然后在PublicRes.xml文件内设置你自己准备的字体，（自己准备的字体需要放到Res文件夹下面），ofd:CGTransform标签内存在内容（字符码），则去字体文件内寻找匹配的文字，没有则显示ofd:TextCode标签内的内容。这我选择使用ofd:TextCode显示内容，ofd:CGTransform标签则全部删掉。
字体文件设置文件 PublicRes.xml 如下
<?xml version="1.0" encoding="UTF-8" standalone="yes"?>
<ofd:Res BaseLoc="Res" xmlns:ofd="http://www.ofdspec.org/2016">
<ofd:Fonts>
<ofd:Font ID="" FontName="CBMOWR+STKaiti" FamilyName="CBMOWR+STKaiti">
<ofd:FontFile>font_1.otf</ofd:FontFile>
</ofd:Font>
<ofd:Font ID="8" FontName="STKaiti" FamilyName="STKaiti">
<FontFile>font.TTF</FontFile>
</ofd:Font>
</ofd:Fonts>
</ofd:Res>
注意 ofd:Font 标签内的ID属性，页面信息XML文件内 ofd:TextObject 标签的font属性和此处的id一致即可引用字体。至于ofd:Font标签内的FontName属性则需要填入字体正确
的头文件信息内的名称.
重点说明标签 ofd:TextObject
ofd:TextObject 标签下的 Boundary 属性：将ofd:TextObject看作一个box，前两个值分别为定位点的坐标，后两个值为X轴和Y轴相对与该定位点的偏移量，ofd:TextObject标签显示内容位 置与XML文件内的顺序无关
ofd:TextCode 标签下的 DeltaX 属性：为字符X轴偏移量，显示的内容有10个，偏移量最少得设置9个，如果显示内容字符数-偏移量数 > 1，则会发生字符重叠现象；
使用dom4j来操作xml文件，测试代码-->
