I am creating a .net (c#) application to merge several PDFs to one pdf
using iTextSharp dll.
When I open this merged file from my folder where it is saved, it opens
successfully, but when I import it in an Electronic Medical Record (EMR)
System and read, it gives file corrupt error.
If I compare the properties of this file created using iTextSharp to
another pdf file which can be imported and read in the EMR, I see the
following:
Properties shown are as follows (file A):
Title:

Application:
PDF Producer: iTextSharp 5.0.2(c)1T3XT BVBA
Fast web View: No
PDF version: 1.4
In the other pdf file (B) which can be imported and opened in my EMR,
the properties are as follows:
Title: Accession Result

Created: Tuesday, May 18, 2010, 6:28:05 PM

Application: APVX
PDF Producer: eTelenext
Fast web View: No
PDF version: 1.3
How can I set the properties same as in file B shown above?
Is there some other setting that may be causing this problem?
This is how I am creating the merged file using itextSharp. Please let
me know what I can do to create a pdf that can be imported and read from
within the EMR system.
To make sure I tried importing the original pdf files saved from the
binary data and successfully opened in the EMR. But I can not open the
merged file created using iTextSharp.
Please help. It is urgent.
1. For each case
a. Read binary data in a Byte Array:
i. Byte[] FileData =
(byte[])dr["DocumentBinary"];
ii.
PDFFileName = _MergedPDFSavePath + dr["FileReportName"].ToString();
b. Write Byte Array to a file:
i. FileStream fs = new FileStream(fileName,
FileMode.Create, FileAccess.ReadWrite);
ii. BinaryWriter bw = new BinaryWriter(fs);
iii. bw.Write(buff);
2. Merge all files created above:
a. PdfReader reader = new PdfReader(ReportFiles[0]);
b. Document doc = new Document(reader.GetPageSizeWithRotation(1));
c. PdfMerge PM = new PdfMerge();
d. PdfMerge.MergeFiles(TargetFile, ReportFiles);
PDFMerge.cs code copied at the end of this message.
3. Create save as dialogue to enable the client to save merged file:
a. Response.ContentType = "application/pdf";
b. Response.AddHeader("content-disposition", "attachment; filename=" +
FName);
c. FileStream sourceFile = new FileStream(TargetFile, FileMode.Open);
d. long FileSize;
e. FileSize = sourceFile.Length;
f. byte[] getContent = new byte[(int)FileSize];
g. sourceFile.Read(getContent, 0, (int)sourceFile.Length);
h. sourceFile.Close();
i. Response.BinaryWrite(getContent);

this code to set pdf version, but the properties still show me version

while (f < sourceFiles.Length)

document.SetPageSize(reader.GetPageSizeWithRotation(i));
document.NewPage();
page = writer.GetImportedPage(reader, i);
rotation = reader.GetPageRotation(i);
if (rotation == 90 || rotation == 270)
{
cb.AddTemplate(page, 0, -1f, 1f, 0, 0,
reader.GetPageSizeWithRotation(i).Height);

else
