一个关与利用iText生成PDF文件的问题

Question

利用iText生成PDF文件,
我做了个PDF模板,这个模板只有一页,如何利用这个模板生成几页的新的 
PDF文件呢?每一页都跟模板相同
我只知道 模板是怎样我生成的PDF文件的布局就是怎样的,模板几页生成的PDF文件就是几页
不知道在此基础上变更
有没有用过这个的教教我
只要告诉我怎么利用只有一页的模板生成有两页内容一模一样的PDF文件就可以了
谢谢了,能有简单的代码就更好了

Answer 1

没人知道吗,用C#生成PDF的好象少啊

生成PDF文件代码如下

}要解决这个问题的思想是想把数据填好,然后在把生成的几个PDF文件合并

Answer 3

要解决这个问题的思想是想把数据填好,然后在把生成的几个PDF文件合并
合并代码如下
 string[] args ={ "C:\\Result.pdf", "C:\\test1.pdf", "C:\\test2.pdf" };
                   try  
                   {

                       // we retrieve the total number of pages 
                       int n = reader.NumberOfPages;

                       document.Open(); 
                       PdfContentByte cb = writer.DirectContent; 
                       PdfImportedPage page; 
                       int rotation; 
                       // step 4: we add content

                               document.SetPageSize(reader.GetPageSizeWithRotation(i)); 
                               document.NewPage(); 
                               page = writer.GetImportedPage(reader, i); 
                               rotation = reader.GetPageRotation(i);

                               } 
                               Console.WriteLine("Processed page " + i); 
                           } 
                           f++; 
                           if (f < args.Length)  
                           {
