我使用itextsharp從模板pdf文件創建pdf。但新的PDF文件被創建爲動態PDF格式。我想將這個文件轉換爲靜態的pdf文件,所以我試圖使用xfaworker。我從itextsharp.licensekey.dll得到「Signature was corrupted」錯誤。我怎樣才能使用xfaworker或其他dll的flatten動態pdf?使用iTextSharp平展動態pdf
public string Create(FaxPDFModel model, MemoryStream ms)
{
string codeBase = Assembly.GetExecutingAssembly().CodeBase;
UriBuilder uri = new UriBuilder(codeBase);
string templatePath = Path.GetDirectoryName(Uri.UnescapeDataString(uri.Path));
PdfReader pdfTemplate = new PdfReader(Path.Combine(Path.Combine(templatePath, "Docs"), "fax_template.pdf"));
PdfStamper stamper = new PdfStamper(pdfTemplate, ms);
stamper.Writer.CloseStream = false;
BaseFont bf = BaseFont.CreateFont(BaseFont.TIMES_ROMAN, "ISO-8859-9", BaseFont.EMBEDDED);
var acroFields = stamper.AcroFields;
acroFields.GenerateAppearances = true;
stamper.FormFlattening = true;
acroFields.AddSubstitutionFont(bf);
acroFields.SetField("Name", "Mutabakat test");
acroFields.SetField("Title", "DANIŞMANLIK");
acroFields.SetField("Department", "test");
acroFields.SetField("Phone", "0 (212) 555 55 55");
stamper.Close();
string path = Path.Combine(Path.Combine(templatePath, "Docs"), System.Guid.NewGuid().ToString());
string pdfPath = path + ".pdf";
Document document = new Document();
PdfWriter writer = PdfWriter.GetInstance(document, new FileStream(pdfPath, FileMode.Create));
XFAFlattener xfaf = new XFAFlattener(document, writer);
ms.Position = 0;
xfaf.Flatten(new PdfReader(ms));
document.Close();
return pdfPath;
}
