iText没有生成预期的PDF格式 [英] iText not generating expected PDF format
问题描述
我正在使用iText进行PDF生成，下面是代码片段。
String template =; //下面给出的内容是为了提高可读性
OutputStream file = new FileOutputStream（new File（D：\\Test.pdf））;
凭证凭证=新凭证（）;
PdfWriter writer = PdfWriter.getInstance（document，file）;
document.open（）;
InputStream is = new ByteArrayInputStream（k.getBytes（））;
XMLWorkerHelper.getInstance（）。parseXHtml（writer，document，is）;
我的模板如下所示：
< HTML>
< head>
< style> .col {padding：3px 20px 3px 20px}< / style>
< / head>
< body style =font-family：tahoma>
< div style =background：rgb（230,230,230）; padding：5px; border：1px solid black;>
< b style =color：rgb（51,153,255）>样本标题< / b>
< img style =float：rightheight =25pxwidth =80pxsrc =resources / images / itext.png/>
< / div>
< br />
< table border ='0'style ='border-collapse：collapse;'>
< tr>
< td class =col> String 1< / td>
< td class =col>：1234354545< / td>
< / tr>
< tr>
< td class =col> String 2< / td>
< td class =col>：rere< / td>
< / tr>
< tr>
< td class =col> String 3< / td>
< td class =col>：ureuiu< / td>
< / tr>
< tr>
< td class =col>日期< / td>
< td class =col>：dfdfjkdjk< / td>
< / tr>
< / table>

< / body>
< / html>
它看起来像浏览器中的给定图像
但在PDF格式中我得到的结果是这样的
我无法找到解决方法。
请查看
你的结果有什么不同？
在你的结果中，您正在使用< br /> 标签，这会导致新的线路操作考虑到前导。当你开始一个新的页面时，前导是0.一旦你有一些正常的段落首次定义一个前导，领先的变化。
在你的例如，领导的定义永远不会发生，所以你必须自己做。例如：
PdfWriter writer = PdfWriter.getInstance（document，file）;
writer.setInitialLeading（12）;
现在，当您使用<$时，前导的值将导致12个用户单位的空行c $ c>< br /> 代码。
至于徽标的对齐方式：我建议您将徽标放入一个两列表，其中文本被添加到第一列，徽标被添加到第二列。
I am working on PDF generation using iText, Below is the code snippet.
String template="";//content given below for more readability
OutputStream file = new FileOutputStream(new File("D:\\Test.pdf"));
Document document = new Document();
PdfWriter writer = PdfWriter.getInstance(document, file);
document.open();
InputStream is = new ByteArrayInputStream(k.getBytes());
XMLWorkerHelper.getInstance().parseXHtml(writer, document, is);
My template looks like this:
<html>
<head>
<style>.col{padding:3px 20px 3px 20px}</style>
</head>
<body style="font-family:tahoma">
<div style="background:rgb(230,230,230); padding:5px ;border:1px solid black;">
<b style="color:rgb(51,153,255)">Sample header</b>
<img style="float:right" height="25px" width= "80px" src="resources/images/itext.png" />
</div>
<br />
<table border='0' style='border-collapse: collapse;'>
<tr>
<td class="col">String 1</td>
<td class="col">: 1234354545</td>
</tr>
<tr>
<td class="col">String 2</td>
<td class="col">: rere</td>
</tr>
<tr>
<td class="col">String 3</td>
<td class="col">: ureuiu</td>
</tr>
<tr>
<td class="col">Date</td>
<td class="col">: dfdfjkdjk</td>
</tr>
</table>

It looks like the given image in browser
But in PDF i am getting something like this
I am not able to find how to fix this.
Please take a look at the ParseHtml12 and the corresponding result: test2015-11.pdf
What is the difference with your result?
In your result, you are using <br /> tags which result in new line operations that take into account the leading. When you start a new page, the leading is 0. The leading changes as soon as you have some normal paragraphs where a leading is defined for the first time.
In your case, the definition of the leading never happens, so you have to do it yourself. For instance:
PdfWriter writer = PdfWriter.getInstance(document, file);
writer.setInitialLeading(12);
Now the value of the leading will result in empty lines of 12 user units when you use the <br /> tag.
As for the alignment of the logo: I suggest that you put that logo in a two column table where the text is added to the first column and the logo to the second column.
