篇首语:本文由小常识网(cha138.com)小编为大家整理,主要介绍了Java 浅析,生成OFD文件相关的知识,希望对你有一定的参考价值。
摘要:这几天遇到个需要,需要提供用户下载电子证照,文件格式为OFD,一上网查瞬间懵了,几乎没有相关的,Google上也没有(咱们国家的国标文件没有相关资料也正常),时间紧,选择最简单的方法来实现,我将需要生成的文件用word做了一份模板,利用网页工具转成OFD文件,这个网站非常良心,不干coder blackmail coder的事儿,这
是地址http://www.yozodcs.com/page/example.html(因为OFD文件没有专业软件帮助几乎很难代码实现),(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,有助于我们用代码操作:
Doc_1文件夹下面是主要内容
Pages下面存放OFD每个页面
下面简单说明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:Area> <ofd:Content> <ofd:Layer ID="0"> <ofd:ImageObject ID="7" ResourceID="6" Boundary="0 -0.3528 210.2557 297.0391" CTM="210.2557 0 0 297.0391 0 0"/> <ofd:TextObject ID="9" Font="8" Size="7.761115550994873" Boundary="47.2723 67.0278 261.0557 15.5222"> <ofd:CGTransform CodePosition="0" CodeCount="17" GlyphCount="17"> <ofd:Glyphs>11738 12862 7255 17457 12235 14764 13842 11859 12078 11931 15952 14729 11465 7256 11113 11465 13610</ofd:Glyphs> </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,这也是OFD文件为何如此DT的地方:
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,由此在页面上确定该box的位置,
也因为该属性,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,第一个值为ofd:TextCode标签内第一个字符和第二个字符的偏移量,有n个字符就有n-1个偏移量,多个用空格隔开,如果你显示的内容
可能存在折行,你需要在模板文件内将显示内容填充满,通过上一层ofd:TextObject标签的Boundary属性的第二个值获取折行Y轴偏移量,折行内容还放不下,你需要调整 Size 属性来
调整字体大小,(这里建议再弄一份小字体文件再需要缩小字体的时候设置对应的Size,DeltaX属性),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;
现在有了模板文件,知道了基本的属性作用,我使用dom4j来操作xml文件,上代码-->

工具类
package util; import java.io.File; import java.io.FileInputStream; import java.io.FileOutputStream; import java.io.IOException; import java.util.Scanner; public class OprationFile { @SuppressWarnings("static-access") public static boolean copyDir(String sourcePath, String newPath) throws IOException { File file = new File(sourcePath); String[] filePath = file.list(); if (!(new File(newPath)).exists()) { (new File(newPath)).mkdir(); } for (int i = 0; i < filePath.length; i++) { if ((new File(sourcePath + file.separator + filePath[i])) .isDirectory()) { copyDir(sourcePath + file.separator + filePath[i], newPath + file.separator + filePath[i]); } if (new File(sourcePath + file.separator + filePath[i]).isFile()) { copyFile(sourcePath + file.separator + filePath[i], newPath + file.separator + filePath[i]); } } return true; } public static void copyFile(String oldPath, String newPath) throws IOException { File oldFile = new File(oldPath); File file = new File(newPath); FileInputStream in = new FileInputStream(oldFile); FileOutputStream out = new FileOutputStream(file);; byte[] buffer=new byte[2097152]; int readByte = 0; while((readByte = in.read(buffer)) != -1){ out.write(buffer, 0, readByte); } in.close(); out.close(); } public static void deleteFiles(File file){ if (file.isDirectory()) { File[] files=file.listFiles(); for (int i = 0; i < files.length; i++) { if (files[i].isDirectory()) { deleteFiles(files[i]); }else { files[i].delete(); } } } file.delete(); } public static void main(String[] args) throws IOException { Scanner sc = new Scanner(System.in); String filePath = sc.nextLine(); deleteFiles(new File(filePath)); } }
下面这个方法来自https://www.cnblogs.com/yzuzhang/p/4763606.html大佬的分享,建议自己写,重载太多不方便传参,这里需要重点说明,OFD文件压缩采用ZIP,一定注意不能有根目录,以我的为例,直接将Doc_1文件夹和OFD.xml文件压缩,用电脑操作也是一样,
package util; import java.io.File; import java.io.FileInputStream; import java.io.FileOutputStream; import java.io.IOException; import java.util.zip.ZipEntry; import java.util.zip.ZipOutputStream; public class ZipUtil { private ZipUtil() { } public static void doCompress(String srcFile, String zipFile,String rootdDirectory) throws IOException { doCompress(new File(srcFile), new File(zipFile),rootdDirectory); } /** * 文件压缩 * * @param srcFile * 目录或者单个文件 * @param zipFile * 压缩后的ZIP文件 */ public static void doCompress(File srcFile, File zipFile,String rootdDirectory) throws IOException { ZipOutputStream out = null; try { out = new ZipOutputStream(new FileOutputStream(zipFile)); doCompress(srcFile, out,rootdDirectory); } catch (Exception e) { throw e; } finally { out.close();// 记得关闭资源 } } public static void doCompress(File file, ZipOutputStream out,String rootdDirectory) throws IOException { doCompress(file, out, "",rootdDirectory); } public static void doCompress(File inFile, ZipOutputStream out, String dir,String rootdDirectory) throws IOException { if (inFile.isDirectory()) { File[] files = inFile.listFiles(); if (files != null && files.length > 0) { for (File file : files) { String name = inFile.getName(); if (!"".equals(dir)) { name = dir + "/" + name; } ZipUtil.doCompress(file, out, name,rootdDirectory); } } } else {
//将根目录干掉,否则无法打开OFD文件 dir = dir.replaceAll(rootdDirectory, ""); ZipUtil.doZip(inFile, out, dir); } } public static void doZip(File inFile, ZipOutputStream out, String dir) throws IOException { String entryName = null; if (!"".equals(dir)) { entryName = dir + "/" + inFile.getName(); } else { entryName = inFile.getName(); } ZipEntry entry = new ZipEntry(entryName); out.putNextEntry(entry); int len = 0; byte[] buffer = new byte[1024]; FileInputStream fis = new FileInputStream(inFile); while ((len = fis.read(buffer)) > 0) { out.write(buffer, 0, len); out.flush(); } out.closeEntry(); fis.close(); } public static void main(String[] args) throws IOException { String rootdDirectory = "OFD"; doCompress("E:/OFD/", "E:/OFD.ofd",rootdDirectory); } }
没了。。。
