iTextSharp "문서에 페이지가 없습니다." 오류

Question

이미지가 포함 된 pdf 파일을 만듭니다. 이미지를 iTextSharp 이미지를 생성 한 후 서버에 저장합니다.

iTextSharp.text.Image backgroundImage = iTextSharp.text.Image.GetInstance(path); 

이 줄에는 "문서에 페이지가 없습니다."라는 오류가 표시됩니다. 여기

는 스택 트레이스입니다 :

location: iTextSharp.text.pdf.PdfPages.WritePageTree() 
    location: iTextSharp.text.pdf.PdfWriter.Close() 
    location: iTextSharp.text.pdf.PdfDocument.Close() 
    location: iTextSharp.text.pdf.PdfWriter.Close() 
    location: iTextSharp.text.DocWriter.Dispose() 
    location: MyProject.Helpers.FileUploadHelper.SaveMarathonCertificateTemplate(HttpRequestBase Request, String _fileName, CertificateOrientation orientation) c:\MyProject\Helpers\FileUploadHelper.cs : line 68 
    location: MyProject.Controllers.CertificateController.Add(Int32 marathonId, MarathonCertificate marathonCertificate) c:\MyProject\Controllers\CertificateController.cs: line 74 

어제 코드가 잘 작동했지만, 이상하게 오늘은이 오류를 받고 있어요. 여기 내 코드는 다음과 같습니다.

using (var fs = new FileStream(pdfFileName, FileMode.Create)) 
{ 
    using (var pdfDoc = new iTextSharp.text.Document()) 
    { 
     if (orientation == CertificateOrientation.HORIZONTAL) 
      pdfDoc.SetPageSize(PageSize.A4.Rotate()); 
     using (var w = PdfWriter.GetInstance(pdfDoc, fs)) 
     { 
      pdfDoc.Open(); 
      pdfDoc.NewPage(); // add Page here 

      iTextSharp.text.Image backgroundImage = iTextSharp.text.Image.GetInstance(path); 

      if (orientation == CertificateOrientation.HORIZONTAL) 
      { 
       backgroundImage.ScaleAbsoluteWidth(Config.PdfActualSizeHorizontal[0]); 
       backgroundImage.ScaleAbsoluteHeight(Config.PdfActualSizeHorizontal[1]); 
      } 
      else if (orientation == CertificateOrientation.VERTICAL) 
      { 
       backgroundImage.ScaleAbsoluteWidth(Config.PdfActualSizeVertical[0]); 
       backgroundImage.ScaleAbsoluteHeight(Config.PdfActualSizeVertical[1]); 
      } 
      backgroundImage.SetAbsolutePosition(0, 0); 
      pdfDoc.Add(backgroundImage); 

      pdfDoc.Close(); 
     } 
    } 
} 

나는 문제가 없습니다. 어떤 해결책이 있습니까?

System.ObjectDisposedException was caught Message=Cannot access a closed file.

새로운 스택 트레이스 :

EDIT:

나는 오류가 이것되고 그 후 이미지 인스턴스

pdfDoc.Add(new Paragraph(" ")); 

를 얻기 전에 한 줄을 추가

이 하나를 시도 :

var path ="path of final pdf to save"; 
var imagePath="path of image that should be paste in final pdf file"; 
iTextSharp.text.Document document = new iTextSharp.text.Document(); 
PdfWriter writer = PdfWriter.GetInstance(document, new FileStream(path, FileMode.Create)); 
iTextSharp.text.Image myImage = iTextSharp.text.Image.GetInstance(imagePath); 
myImage.ScaleAbsoluteHeight(document.PageSize.Height); 
myImage.ScaleAbsoluteWidth(document.PageSize.Width); 
myImage.Alignment = Element.ALIGN_CENTER; 
document.Add(myImage); 
document.Close(); 

모두입니다.
