FlexPaper的深入了解和应用
最近做项目需要用到flexpaper,所以想借此机会好好的研究一下。
这是官方的下载地址:http://flexpaper.devaldi.com/download/,flexpaper是一款付费的软件,它有免费版本但是有限制的(浏览时会显示flexpaper的logo并且限制只能浏览10页)。当然网上有许多破解版本可以使用网上很容易找到。我们公司项目会用到正版但还没有到位,所以本文是以试用版本(有限制的)来研究的。话不多说我们开始。
首先我做的是web项目所以下载时选择ASP.NET/PHP/Java选项
接下来是下载的部分,我们可以看到有PDF2JSON、PDFTk、SWFTOOLS,这三个是PDF文件的转换工具我们一并下载。Zine/Classic是flexpaper的不同版本他们在具体样式上也有所不同,具体的可以在官网的examples上看到。我们这里下载Classic,因为这个版本是可以添加标签和注解的。
下载完我们可以看到它的目录结构,我们需要的是css、js、locale、FlexPaperViewer.swf以及UI_开头的html文件
接下来我们新建一个web项目,把css、images、js、FlexPaperViewer.swf、UI_开头的html导入项目,建立docs和pdf文件夹把转换好的格式文件放进去
至于pdf文件的转换我值写出控制台的命令就不再这里细说了:
pdf转换成单个swf文件
pdf2swf.exe H:\Paper.pdf -o H:\Paper.swf -f -T 9 -t -s storeallcharacters -s linknameurl
pdf按页转换成带页号的swf文件(pdf名_页号.swf)
pdf2swf.exe H:\Paper.pdf -o H:\pages\Paper_%.swf -f -T 9 -t -s storeallcharacters -s linknameurl
pdf转换成单个json文件
pdf2json.exe H:\Paper.pdf -enc UTF-8 -compress H:\Paper.js
pdf按页转换成带页号的js文件(pdf名_页号.js)
pdf2json.exe H:\Paper.pdf -enc UTF-8 -compress -split 28 H:\pages\Paper_%.js
把pdf按页分割
pdftk.exe H:\Paper.pdf burst output H:\pages\Paper_%02d.pdf compress
以上就是转换命令了,只要打开相应的exe文件所在的目录SHIFT+右键打开命令行,修改成自己要转换的文件跟路径就可以了。
接下来就是关键的页面了
<%@ page language="java" contentType="text/html; charset=utf-8" pageEncoding="utf-8"%> <!DOCTYPE html> <html> <head> <title>flexpaper_demo</title> <meta content="charset=utf-8"> <link rel="stylesheet" type="text/css" href="/css/flexpaper.css" /> <script type="text/javascript" src="/js/jquery.min.js"></script> <script type="text/javascript" src="/js/jquery.extensions.min.js"></script> <script type="text/javascript" src="/js/flexpaper.js"></script> <script type="text/javascript" src="/js/FlexPaperViewer.js"></script> <script type="text/javascript" src="/js/flexpaper_handlers.js"></script> </head> <body> <div id="documentViewer" class="flexpaper_viewer" style="position: absolute; left: 10px; top: 10px; width: 800px; height: 500px"></div> <script type="text/javascript"> //判断是否是触屏(移动设备) $.get((!window.isTouchScreen) ?

package com.demo.util; import java.io.File; import java.io.FileInputStream; public class FlexPaperUtil { /** * 以二进制形式获取文件内容 * * @param filePath * 文件路径 * @return */ public static byte[] file_get_contents(String filePath) { byte[] con = { 0 }; // 判断路径是否为空 if (filePath == null || filePath == "") return con; try { File f = new File(filePath); // 判断是否为文件及是否可读 if (!f.isFile() || !f.canRead()) return con; FileInputStream fstream = new FileInputStream(filePath); con = new byte[(int) f.length()]; fstream.read(con); fstream.close(); } catch (Exception e) { e.printStackTrace(); } return con; } }
定义一个controller
package com.demo.web; import java.io.*; import javax.servlet.http.HttpServletRequest; import javax.servlet.http.HttpServletResponse; import org.springframework.stereotype.Controller; import org.springframework.web.bind.annotation.PathVariable; import org.springframework.web.bind.annotation.RequestMapping; import org.springframework.web.bind.annotation.RequestParam; import com.demo.util.FlexPaperUtil; @Controller public class FlexController { @RequestMapping(value = "/flex") public String flex(HttpServletRequest request, HttpServletResponse response) { return "flexpaper"; } @RequestMapping(value = "/flex/view/{name}") public void view(HttpServletRequest request, HttpServletResponse response, @PathVariable String name) throws IOException { BufferedOutputStream outs = new BufferedOutputStream(response.getOutputStream()); String mySwfFilePath = request.getSession().getServletContext().getRealPath("/") + "\\docs\\pages\\" + name + ".swf"; System.out.println(mySwfFilePath); byte[] content = FlexPaperUtil.file_get_contents(mySwfFilePath); response.setContentLength(content.length); outs.write(content); outs.flush(); outs.close(); } @RequestMapping(value = "/flex/view") public void view2(HttpServletRequest request, HttpServletResponse response, @RequestParam String name) throws IOException { String dir = ""; if (name.contains("pdf")) { dir = "\\pdf\\"; } else { dir = "\\docs\\"; } BufferedOutputStream outs = new BufferedOutputStream(response.getOutputStream()); String mySwfFilePath = request.getSession().getServletContext().getRealPath("/") + dir + name; System.out.println(mySwfFilePath); byte[] content = FlexPaperUtil.file_get_contents(mySwfFilePath); response.setContentLength(content.length); //弹出错误对话框 // outs.write("Error:aaa".getBytes()); outs.write(content); outs.flush(); outs.close(); } }
接下来是通用api:
页数跳转: $FlexPaper("documentViewer").gotoPage(5); 适应控件宽度: $FlexPaper("documentViewer").fitWidth(); 适应控件高度: $FlexPaper("documentViewer").fitHeight(); 获取当前页数: $FlexPaper("documentViewer").getCurrPage(); 打印: $FlexPaper("documentViewer").printPaper(); 下一页: $FlexPaper("documentViewer").nextPage(); 上一页: $FlexPaper("documentViewer").prevPage(); 搜索: $FlexPaper("documentViewer").searchText(""); 切换显示模式:Two Page双页/Portrait单页 $FlexPaper("documentViewer").switchMode("Portrait");
==============================================================================================
最后是注释的api:
添加高亮:
$FlexPaper("documentViewer").addMark({ id : "1", type : "highlight", pageIndex : 1, displayFormat : "flash", readonly : false, selection_text : "The UK", selection_info : "1;0;5", color : "#c2f785", });
为高亮部分添加注释:不知道什么原因要运行两次才能出现注释框
$FlexPaper("documentViewer").addMark({ id : "2", type : "highlight", pageIndex : 1, displayFormat : "flash", readonly : false, has_selection : true, selection_text : "The UK", selection_info : "1;0;5", note : "这是注释", color : "#c2f785", //注释框顶点坐标 positionX : 350, positionY : 150, //注释框尺寸 width : 200, height : 200 });
在指定点插入注释:
$FlexPaper("documentViewer").addMark({ id : "3", type : "note", pageIndex : 1, displayFormat : "flash", readonly : false, //注释框是否收起 collapsed : false, note : "这是注释", points : "100,10", //注释框顶点坐标 positionX : 100, positionY : 150, //注释框尺寸 width : 200, height : 200, });
框选指定区域插入注释:
$FlexPaper("documentViewer").addMark({ id : "4", type : "drawing", pageIndex : 1, displayFormat : "flash", note : "这是注释", //框选区域的顶点坐标和对角点坐标 points : "10,10:200,150", color : "#c2f785", //注释框顶点坐标 positionX : 350, positionY : 150, //注释框尺寸 width : 200, height : 200, });
添加涂鸦:这个点会比较多
$FlexPaper("documentViewer").addMark({ id : "5", type : "drawing", pageIndex : 1, displayFormat : "flash", points : "91.55766944114157,174.79191438763377:85,174:82,174:82,168:76, 168:74,168:68,168:65,168:59,168:56,168:50,168:47,168:41,168:38, 168:32,168:29,168:23,168:23,174:23,177:20,177:20,183:20,186:20, 192:20,195:20,201:20,204:20,210:20,213:20,219:23,219:23,222:23, 228:29,228:29,231:29,237:32,237:32,240:32,245:38,245:38,248:38, 254:41,254:47,254:47,257:50,257:50,263:56,263:59,263:65,263:65, 266:68,266:74,266:74,272:76,272:82,272:85,272:91,272:94,272:94, 275:100,275:103,275:109,275:112,275:118,275:121,275:127,275:130, 275:136,275:139,275:139,281:145,281:148,281:154,281:157,281:162, 281:165,281:171,281:174,281:180,281:180,275:183,275:189,275:192, 275:198,275:198,272:201,272:207,272:210,272:216,272:216,266:219, 266:219,263:225,263:225,257:225,254:225,248:225,245:225,240:225, 237:225,231:225,228:225,222:225,219:225,213:225,210:219,210:219, 204:216,204:216,201:210,201:207,201:207,195:201,195:198,195:198, 192:192,192:189,192:183,192:180,192:180,186:174,186:171,186:171, 183:165,183:162,183:157,183:154,183:148,183:145,183:145,177:139, 177:139,174:136,174:130,174:127,174:121,174:118,174:112,174:109, 174:103,174:100,174:94,174:91,174", color : "#FA1100", });
最后是获取当前页的所有注释:可以根据下面的属性把注释存入数据库
var marks = $FlexPaper('documentViewer').getMarkList(); for (var i = 0; i < marks.length; i++) { console.log("id:" + marks[i].id); console.log("type:" + marks[i].type); console.log("pageIndex:" + marks[i].pageIndex); console.log("displayFormat:" + marks[i].displayFormat); console.log("readonly:" + marks[i].readonly); console.log("collapsed:" + marks[i].collapsed); console.log("has_selection:" + marks[i].has_selection); console.log("selection_text:" + marks[i].selection_text); console.log("selection_info:" + marks[i].selection_info); console.log("note:" + marks[i].note); console.log("points:" + marks[i].points); console.log("color:" + marks[i].color); console.log("positionX:" + marks[i].positionX); console.log("positionY:" + marks[i].positionY); console.log("width:" + marks[i].width); console.log("height:" + marks[i].height); }
