Post subject:  Getting error SplittingPDF into Mulitple PDFs
I get this error in PdfSharp.pdf folder- PdfPages.cs- ImportExternalPage when I try to use the sample code for SplitDocument:

A PDF document must be opened with PdfDocumentOpenMode.Import to import pages from it.

I'm really not sure what I am doing wrong, since the code seems very straight forward. Here is the code I use that gets the error:

filename = "test.PDF";
File.Copy(Path.Combine(@"C:\PDFs\", filename),
Path.Combine(Directory.GetCurrentDirectory(), filename), true);

// Open the file
PdfDocument inputDocument = PdfReader.Open(filename, PdfDocumentOpenMode.ReadOnly);

string name = Path.GetFileNameWithoutExtension(filename);
for (int idx = 0; idx < inputDocument.PageCount; idx++)
{
// Create new document
PdfDocument outputDocument = new PdfDocument();
outputDocument.Version = inputDocument.Version;
outputDocument.Info.Title =
String.Format("Page {0} of {1}", idx + 1, inputDocument.Info.Title);
outputDocument.Info.Creator = inputDocument.Info.Creator;

// Add the page and save it
outputDocument.AddPage(inputDocument.Pages[idx]);
outputDocument.Save(String.Format("{0} - Page {1}.pdf", name, idx + 1));
}

Thanks in advance for any help.

If you replace PdfDocumentOpenMode.ReadOnly by PdfDocumentOpenMode.Import (as the error message says) your code will work.

Stefan ,

How to do it? I found PdfDocumentOpenMode is a property in PdfDocument, but it's internal.

Thanks
James

It's a parameter of
Code:
PdfReader.Open()

PdfReader.Open returns the opened PdfDocument.

This my code:
pulic void MyMethod(PdfPage pdfPage)
{
PdfDocument pdfDocument = new PdfDocument();
pdfDocument.Pages.Add(pdfPage);
GS ghostscript = new GS();
System.Drawing.Image image = ghostscript.PdfToPng(pdfDocument, 1, 96);
Stream stream = new MemoryStream();
image.Save(stream, System.Drawing.Imaging.ImageFormat.Png);
...
}
I try to use Reader.Open(), but it need pass in some parameters, I don't know what it stand for.

Please help me, thanks
James

PdfPage pdfPage is come from base class in another assembly which I have no source code, I just try to override the abstract method.

I don't know if base class use Reader.Open() or not

That other assembly must be changed - or replaced.
No source code? Try .NET Reflector ...

PdfReader.Open(...) returns the PdfDocument.
You must specify at open that you want to open the document for import.
