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

            });  
        });  
    </script>  
</body>  
</html>  
前台好了现在是后台,定义一个工具类 
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();  
    }  
}  
运行后的结果



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);
}
