I'm creating a pdf file with an image. I'm getting the image, first saving it into the server, after creating an iTextSharp image with it;
iTextSharp.text.Image backgroundImage = iTextSharp.text.Image.GetInstance(path);
On this line I'm getting an error "The document has no pages."
Here is the StackTrace:
location: iTextSharp.text.pdf.PdfPages.WritePageTree()
location: iTextSharp.text.pdf.PdfWriter.Close()
location: iTextSharp.text.pdf.PdfDocument.Close()
location: iTextSharp.text.pdf.PdfWriter.Close()

Yesterday code was working well, but weirdly today I'm getting this error. Here is my code:
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();
}
}
}
I cant't get the problem. Is there any solution?
EDIT:
I added a line before getting Image instance
pdfDoc.Add(new Paragraph(" "));
After that the error becomes to this:
System.ObjectDisposedException was caught Message=Cannot access a closed file.

Try this one:
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();
Thats all.
