I’m a java guy, but I’m curious about this method signature:
static bool RewritePdfFiles(string pdfFile, string outputFile)
if you are trying to merge PDFs, shouldn’t you be doing this:
static bool MergePdfs(// an array of PDFs, string mergedPdfFile);
or maybe even
static [bytes or a stream] MergePdfs(// an array of PDFs);
and let the caller deal with the output?

Subject: Re: [iText-questions] PDF merge - filesize after
OK attached are my example PDFs.
My code is below:
public
static bool RewritePdfFiles(string pdfFile, string outputFile)
{
bool bOK = true;
iTextSharp.text.pdf.
PdfSmartCopy pdfWriter = null;
iTextSharp.text.pdf.
PdfReader pdfReader = null;
//no input file found
if (pdfFile == null || pdfFile == "")
{
throw new System.Exception("There is no input pdf files to merge!");
}
//string[] fileList = pdfFiles;
//init
int pageOffset = 0;
//ArrayList master = new ArrayList();
IList<Dictionary<string, object>> master = new List<Dictionary<string,
object>>();
iTextSharp.text.
Document pdfDocument = null;
int totalProcessedPages = 0;
try
{
FileStream tmpFile = System.IO.File.Create(outputFile);
//foreach (KeyValuePair<string, string> kvp in pdfFiles)
//{
//Key - Filepath
//Value - Bookmark
int currentDocumentPages = 0;
pdfReader =
new iTextSharp.text.pdf.PdfReader(pdfFile);
pdfReader.RemoveUnusedObjects();
pdfReader.ConsolidateNamedDestinations();
int pdfNumberOfPages = pdfReader.NumberOfPages;
//String boundsString = "";
IList<Dictionary<string, object>> bookmarks = new List<Dictionary<string,
object>>();
// IList<Dictionary<String, Object>> bookmarks = new ArrayList<HashMap<String,
Object>>();
int relativeOffset = pdfNumberOfPages;
currentDocumentPages += relativeOffset;
pageOffset += relativeOffset;
Console.WriteLine(pdfFile + ": " + currentDocumentPages + " pages to be
added.");
if (pdfWriter == null)
{
// step 1: creation of a document-object
pdfDocument =
new iTextSharp.text.Document(pdfReader.GetPageSizeWithRotation(1));
// step 2: we create a writer that listens to the document
//pdfWriter = new iTextSharp.text.pdf.PdfCopy(pdfDocument, tmpFile);
pdfWriter =
new iTextSharp.text.pdf.PdfSmartCopy(pdfDocument, tmpFile);
pdfWriter.CompressionLevel =
PdfStream.BEST_COMPRESSION;
pdfWriter.SetFullCompression();
// step 3: we open the document
iTextSharp.text.pdf.
PdfName version = new iTextSharp.text.pdf.PdfName("8");
pdfWriter.SetPdfVersion(version);
pdfDocument.AddCreator(
"Cad-Capture");
pdfDocument.Open();
//}
}
// step 4: we add content
if (pdfReader != null)
{
int numPages = pdfReader.NumberOfPages;
for (int count = 1; count <= numPages; count++)
{
pdfWriter.AddPage(pdfWriter.GetImportedPage(pdfReader, count));
}
}
else
{
throw new System.Exception("Reader is null");
}
pdfWriter.FreeReader(pdfReader);
pdfReader.Close();
totalProcessedPages += currentDocumentPages;
Console.WriteLine(currentDocumentPages + " pages processed correctly.");
//}
Console.WriteLine("Total processed pages: " + totalProcessedPages + ".");

}
Console.WriteLine("File " + outputFile + " created.");
}
catch (Exception e)

false;

}
finally

}
return bOK;
