使用飞碟(xHTMLRenderer)和iText生成页眉/页脚

Question

使用飞碟(xHTMLRenderer)和iText生成页眉/页脚

fly*_*ine 25 java pdf itext flying-saucer

我意识到之前已经问过这个问题(我查看了所有解决方案并尝试了所有这些)但我仍然在尝试生成一个带有页眉和页脚的pdf文档,并在每个页面上重复.

我正在使用flying saucerR8,iText2.0.8我已经尝试了许多不同的方法来使其工作,但到目前为止无济于事.我测试的一些方法是https://gist.github.com/626264,使用运行元素和边距框 http://pigeonholdings.com/projects/flyingsaucer/R8/doc/guide/users-guide-R8.html# xil_40(css3功能),飞碟r7指南,不适用于r8 http://today.java.net/pub/a/today/2007/06/26/generating-pdfs-with-flying-saucer -and-itext.html #page-specific-features,很多其他方法对我不起作用.

我的标题div包含2个带图像的div,我的页脚仅用于页面编号.html被放入一个StringBuffer被调用的buf中.

buf.append("<head>");
    buf.append("<title>blabla</title> ");
    buf.append("<style type='text/css' media='print'>  ");
    buf.append("@page { size:8.5in 11in; padding:1em; @bottom-left { content: element(footer); } } ");
    buf.append("#footer { font-size: 90%; font-style: italic;  position: running(footer); top: 0; left: 0; }");
    buf.append("#pagenumber:before { content: counter(page); } ");
    buf.append("#pagecount:before { content: counter(pages); } ");
buf.append("</style></head>");
buf.append("<body>");
 buf.append("<div class='header' style='clear:both;'>");
    buf.append("<div id='moneyLogo' style='float:left'>"); 
    buf.append("<img src='logo.jpg' alt='Some alt text' />");
    buf.append("</div>");
    buf.append("<div id='canLogo' style='float:right'>");
    buf.append("<img src='someImg.gif' alt='alt text' />");
    buf.append("</div>");
    buf.append("<h3 style='text-align:center; clear:both;'>alt text</h3>");
    buf.append("<div style='text-align:center;'>");
    buf.append("Some texy text");
    buf.append("<br />"););
    buf.append("</div>");
    buf.append("</div><br /><br />");
buf.append("<div id='footer'>  Page <span id='pagenumber'/> of <span id='pagecount'/> </div>");

    buf.append("</body>");
    buf.append("</html>");

我的pdf生成正常,除了标题只出现在第一页,页脚只出现在最后一页的底部.当我把html通过w3c验证器时它出来很好,但是当我使用他们的CSS验证器时,它说它们是解析错误的行@page { size:8.5in 11in; padding:1em; @bottom-left { content: element(footer); } }

据我所知,我读到的所有指南都很好.我还听说W3C CSS验证器对于CSS3规范是不完整的,所以我认为它是验证者错了.

如果有人能给我一些关于在哪里寻找或想法的提示,那将使我的一周:)

ps必须使用飞碟R8和/或iText 2.0.8

这是一个工作示例:

package com.sg2net.test;

import java.io.FileNotFoundException;
import java.io.FileOutputStream;

import org.xhtmlrenderer.pdf.ITextRenderer;

import com.lowagie.text.DocumentException;

public class XHTMLRenderer8 {

    /**
     * @author Giovanni Cuccu
     */
    public static void main(String[] args) throws FileNotFoundException, DocumentException {
        ITextRenderer renderer = new ITextRenderer();
        String content="<html><head><style>\n" +
          "div.header {\n" +
          "display: block; text-align: center;\n" + 
          "position: running(header);}\n" +
          "div.footer {\n" +
          "display: block; text-align: center;\n" + 
          "position: running(footer);}\n" +
          "div.content {page-break-after: always;}" +
          "@page { @top-center { content: element(header) }}\n " +
          "@page { @bottom-center { content: element(footer) }}\n" +
          "</style></head>\n" +
          "<body><div class='header'>Header</div><div class='footer'>Footer</div><div class='content'>Page1</div><div>Page2</div></body></html>";
        renderer.setDocumentFromString(content);
        renderer.layout();
        renderer.createPDF(new FileOutputStream("test.pdf"));

    }

}

这是使用以下XHTML文档

<html>
<head>
<style>
div.header {
    display: block; text-align: center; 
    position: running(header);
}
div.footer {
    display: block; text-align: center;
    position: running(footer);
}
div.content {page-break-after: always;}
@page {
     @top-center { content: element(header) }
}
@page { 
    @bottom-center { content: element(footer) }
}
</style>
</head>
<body>
    <div class='header'>Header</div>
    <div class='footer'>Footer</div>
    <div class='content'>Page1</div>
    <div>Page2</div>
</body>
</html>

经过大量的研究和测试,我想出了一个真正有效的解决方案.

你可以控制:

- 编辑margin-top的标题高度;

- 通过编辑边距底部的页脚高度;

- 通过编辑div.content宽度的内容宽度.

页码显示在页脚.

见下面的代码:

<html>
<head>
<style>

@page{

    @bottom-left {                 
        content: element(footer);  
        vertical-align: top;
        padding-top: 10px;
/*      border: solid red;    */
    }

    @top-right {
        content: element(header); 
        vertical-align: bottom;
        padding-bottom: 10px;
/*          border: solid green;   */
    }

    size: A4 portrait;
    margin-top:5.5cm; 
    margin-left:3cm; 
    margin-right:2cm; 
    margin-bottom:3.3cm; 
}

div.header {
    display: block;                     
    position: running(header);
    border-bottom: 1px solid black;
}

div.footer {
    margin-top: 0.5cm;
    display: block;
    position: running(footer);
    border-top: 1px solid black; 
}

div.content {
/*  border: solid purple;  */
    display: block;
    width: 15.4cm; 
    text-align: justify;
}

#pagenumber:before {
    content: counter(page);
}

#pagecount:before {
    content: counter(pages);
}

</style>
</head>
<body>

    <div class="header">
        This is the header that will repeat on every page at top
    </div>

    <div class="footer" >
        <p>This is the footer that will repeat on every page at bottom</p>
        <p>Page <span id="pagenumber"></span> of <span id="pagecount"></span></p>/
    </div>

    <div class="content">
        <p>This is the content</p><p>This is the content</p><p>This is the content</p>
        <p>This is the content</p><p>This is the content</p><p>This is the content</p>
