I found the source of this problem.
The source of this problem may be the PDFStamper.GetImportedPage function.
Below code makes the PDF file which size is almost twice of original PDF
file nevertheless calling SetFullCompression.
Dim reader As New PdfReader("src.pdf")
Dim stamper As New PdfStamper(reader, New FileStream("output1.pdf",
FileMode.Create))
stamper.GetImportedPage(reader, 1)
stamper.SetFullCompression()
stamper.Close()
reader.Close()
If calling GetImportedPage is omitted, the size of output PDF file is
reduced to half.
I don't know why it happens but I see how to fix my problem.
I have tried with latest iTextSharp and VS.NET 2003.
