Freely fill PDF form with the help of iText or iTextSharp
iText(java version) and iTextSharp(dotnet version) are very powerful libraries to create and manipulate PDF, but this time, I just want to talk about how to fill PDF form with the help of iText or iTextSharp.
for java version, please visit http://itextdocs.lowagie.com/tutorial/#part5, there are many examples about fill or create PDF form.
for dotnet version(C#),
the easiest example is
PdfReader reader = new PdfReader("SimpleRegistrationForm.pdf");
PdfStamper stamp1 = new PdfStamper(reader, new FileStream("registered.pdf",FileMode.Create));
AcroFields form1 = stamp1.AcroFields;
form1.SetField("name", "Steven");
form1.SetField("address", "http://blog.rubypdf.com");
form1.SetField("postal_code", "200051");
form1.SetField("email", "rocsky@gmail.com");
stamp1.Close();
reader.Close();
and if you want to fill CJK(Chinese, Japanese and Korean) characters to PDF from, have a look the following code,
BaseFont.AddToResourceSearch("iTextAsian-1.0.dll");
BaseFont.AddToResourceSearch("iTextAsianCmaps-1.0.dll");
BaseFont font = BaseFont.CreateFont("STSong-Light", "UniGB-UCS2-H", BaseFont.EMBEDDED);
//if you want to use truetype fonts
//BaseFont font = BaseFont.CreateFont("c:\\windows\\fonts\\STSONG.TTF", BaseFont.IDENTITY_H, BaseFont.EMBEDDED);
PdfReader reader = new PdfReader("SimpleRegistrationForm.pdf");
PdfStamper stamp1 = new PdfStamper(reader, new FileStream("registered.pdf",FileMode.Create));
AcroFields form1 = stamp1.AcroFields;
//if the field you want to fill CJK characters, but the font it used does not support cjk, you need modify it before fill.
form1.SetFieldProperty("name","textfont",font,null);
//fill the form now
form1.SetField("name", "小李");
form1.SetField("address", "http://blog.rubypdf.com");
form1.SetField("postal_code", "200051");
form1.SetField("email", "rocsky@gmail.com");
stamp1.Close();
reader.Close();
