field_merge: Example code of Early Access iText(how to fill PDF form with iTextSharp)-优快云博客

本示例代码展示了如何使用iTextSharp库在PDF文件中进行字段合并及展平操作。通过命令行参数接收输入PDF文件路径、输出PDF文件路径及待设置的字段值。代码首先读取源PDF文件，然后利用PdfStamper对象将字段值写入并选择是否展平表单字段。

using System;
using iTextSharp.text;
using iTextSharp.text.pdf;
using System.IO;
public class field_merge
{

     private static void   usage()
    {

        System.Console.Out.WriteLine( " Field merging and flattening " );
        System.Console.Out.WriteLine( " usage: field_merge [-f] infile_pdf outfile_pdf [[name1=value1]

[namex=valuex]] " );
        System.Console.Out.WriteLine( "     -f - flatten the fields " );
    }


    [STAThread]
     public static void   Main( string [] args)
    {
         if (args.Length < 2 )
        {
            usage();
             return ;
        }
         int idx = 0 ;
         if (args[ 0 ].Equals( " -f " ))
             ++ idx;
         if (args.Length - idx < 2 )
        {
            usage();
             return ;
        }
         string in_pdf = args[idx];
         string out_pdf = args[idx + 1 ];
         try
        {
            PdfReader reader = new PdfReader(in_pdf);
            PdfStamper stamp = new PdfStamper(reader, new FileStream(out_pdf, FileMode.Create));
            AcroFields form = stamp.AcroFields;
             for ( int k = idx + 2 ; k < args.Length; ++ k)
            {
                 string t = args[k];
                 int x = t.IndexOf((System.Char) ' = ' );
                 if (x > 0 )
                {
                     string field = t.Substring( 0 , (x) - ( 0 ));
                     string value_Renamed = t.Substring(x + 1 );
                    form.SetField(field, value_Renamed);
                }
            }
             if (idx > 0 )
                stamp.FormFlattening = ( true );
            stamp.Close();
            System.Console.Out.WriteLine( " Done. " );
        }
         catch (System.Exception e)
        {
            System.Console.Error.WriteLine(e.Message);
        }
    }
}
