IText7 PDFHtml generator with header and footer for C#

I am trying to generating a PDF from predefined HTML content. I managed to generate the content, yet without the required HTML Header, HTML Footer, and Arabic language is not supported as well.
My requirements:
Arabic language support.
The ability to generate more than 10 pages.
The footer may differ from one page to another.
There is a web application that sends a request to a WCF service, and the service returns a byte array containing the PDF.
So, I have been searching for a couple of days for a good tool and I found SelectPdf, it is perfect except that it is NOT free, so the only solution is IText7 PDFHtml.
The thing is this library has good documentation for JAVA, and I am really struggling in following the C# examples and converting from JAVA API to C# code.
Anyone has done something similar before with c#?

After a long process of searching and trying, I have got it working and achieved the following features:
Image in the header.
Base64 image in the footer, in addition to the ability to write some text in the other side in the footer.
Generating the same footer for all pages except for the last one.
the number of the generated pages was unlimited.
Page numbering.
All the previous features were free of charge, however, supporting Arabic language needs a license, so I have to pay anyway :)
Kindly find below my C# code and post your improvements if you have any.

I was trying to get a stream as an output, so if you want that as well you can use the following in your main service:
public byte[] GetData()
{
MemoryStream stream = new Pdfgenerator().createPdf();
byte[] arr = stream.ToArray();
return stream.ToArray();
}

A generic error occurred in GDI+ while trying to print streams

So I have a function that renders a Queue Stream class. Based on a conditional, I would like to add an additional byte array to this queue. I thought I could do this by converting the byte array to a stream, and then Enqueueing it with this additional stream.
I do notice that the count of the streams goes up after enqueueing the original stream, and I pass that into a function that prints the streams. This is where I receive the exception "A generic error occured in GDI+."
EDIT: After going through each page, I realized that when combining the TermsandConditions Byte array to the Stream Queue, it was showing as just one byte Array, where as the T&C's is 2 pdfs.
So my next question is how to convert a pdf to an image?
Here's the function where I'm combining the queues:
internal static void DoPrintInvoice(int orderID, SalesOrderBLL.DocumentType doctype, string printer, int copies, List<string> lines)
{
using (var context = rempscoDataContext.CreateReadOnlyContext())
using (MiniProfiler.Current.Step("DoPrintInvoice()"))
{
// Generate Report
using (var report = GetSalesOrderReport(orderID, _DocumentTypeDescriptions[doctype], doctype != DocumentType.InvoiceLetterhead, lines))
{
// render queue streams for printing
var streams = PrintingBLL.RenderStreams(report, landscape: false);
//add additional byte array to stream.
var TermsAndConditions = GetTermsAndConditions().ToArray();
Stream TCStream = new MemoryStream(TermsAndConditions);
if (doctype == DocumentType.OrderAcknowledgement)
{
streams.Enqueue(TCStream);
}
// render and save pdf in background, print report
BackgroundTask.ParallelInvoke(
() => SaveSalesOrderPDF(orderID, doctype, report),
() => PrintingBLL.PrintStreams(streams, string.Format("Sales Order ({0})", report.DisplayName), printer, copies, false)
);
}
}
}
Then here's the PrintStreams function:
internal static void PrintStreams(Queue<Stream> streams, string documentName, string printer, int copies, bool landscape)
if (copies > 0)
{
// get printer details
using (var pd = new PrintDocument())
{
lock (_PrintLock)
{
pd.PrinterSettings.PrinterName = printer.Trim();
if (!pd.PrinterSettings.IsValid)
throw new ArgumentOutOfRangeException(string.Format("Invalid printer \"{0}\". Please try again with a different printer.", printer));
}
pd.DocumentName = documentName;
pd.PrintController = new StandardPrintController();
pd.PrinterSettings.Copies = (short)copies;
pd.PrinterSettings.Collate = true;
pd.PrinterSettings.DefaultPageSettings.PaperSize = pd.PrinterSettings.PaperSizes.Cast<PaperSize>().First(ps => ps.Kind == PaperKind.Letter);
pd.DefaultPageSettings.Landscape = landscape;
pd.DefaultPageSettings.Margins = new Margins()
{
Top = 0,
Bottom = 0,
Left = 0,
Right = 0,
};
var numPages = streams.Count;
var currentPage = 0;
pd.PrintPage += (s, ev) =>
{
BackgroundTask.SetCurrentStatus(
currentPage / numPages,
string.Format("Printing page {0} of {1}. [{2}]", currentPage, numPages, documentName));
// get next page
var ms = streams.Dequeue();
// if we have any streams left, then we have another page
ev.HasMorePages = streams.Any();
// reset stream
ms.Position = 0;
// read page image
var image = new Metafile(ms);
var r = new Rectangle()
{
X = 0,
Y = 0,
Width = 825,
Height = 1075,
};
if (landscape)
{
r.Height = 825;
r.Width = 1075;
}
// draw image directly on page
ev.Graphics.DrawImage(image, r);
// destroy stream
ms.Close();
currentPage++;
};
try
{
lock (_PrintLock)
pd.Print();
BackgroundTask.SetCurrentStatus(100, string.Format("Finished printing {0}", documentName));
}
catch (Exception e)
{
BackgroundTask.SetCurrentStatus(0, string.Format("Printing Error: {0}", e.Message));
throw new InvalidOperationException(
string.Format("The document failed to print. Arguments were: documentName = {0}; printer = {1}; copies = {2}; landscape = {3}",
documentName,
printer,
copies,
landscape),
e);
}
}
}

Passing in a HttpPostedFileWrapper variable to a function breaks another function. Image validation and conversion in C#

So basically this part of the program is editing/uploading a new profile picture to a user's account. Previously, it worked fine. Then I decided to add in some picture validations (picture has to have certain dimensions, etc). So I made a separate Helper class for that that takes in the HttpPostedFileWrapper variable initialized in the controller.
So, in this controller function, I initialize a new instance of the ValidateImage class which holds two functions (DoValidation and Resize).
The Resize function was working fine until I added the DoValidation function and I feel like it has something to do with the memory stream.
I now get an "Invalid Parameter" error in the ResizeImage function (see below), even though I never changed that code and was working fine previously. Does it have something to do with the filestream not being closed properly or something?
Here is the code:
//Controller.cs
public virtual ActionResult EditMyProfilePicture(bool? ignore)
{
var loggedInEmployee = this.EmployeeRepos.GetEmployeeByUserName(User.Identity.Name);
int tgtWidth = 250, tgtHeight = 250;
try
{
// get a reference to the posted file
var file = Request.Files["FileContent"] as HttpPostedFileWrapper;
ValidateImage img = new ValidateImage();
if (file != null && file.ContentLength > 0)
{
// isolate the filename - IE returns full local path, other browsers: just the file name.
int index = file.FileName.LastIndexOf("\\");
// if not IE, index will be -1, but -1 + 1 = 0 so we are okay.
string fileName = file.FileName.Substring(index + 1);
// Validate the image
img.DoValidation(file, tgtWidth, tgtHeight);
if (!img.IsValidated)
{
throw new ArgumentException(img.Message);
}
else
{
byte[] resizedImg = img.Resize(file, tgtWidth, tgtHeight);
this.EmployeeRepos.SaveProfileImage(loggedInEmployee.EmployeeCode, resizedImg);
}
return RedirectToAction(MVC.Employees.EditMyProfile());
}
else
{
throw new ArgumentException("Please select a file to upload.");
}
}
catch (Exception ex)

// check for image too small
if (curHeight < tgtHeight || curWidth < tgtWidth)
{

IsValidated = false;
return;
}
// check for image is square
else if (curHeight != curWidth)
{

IsValidated = false;
return;
}
else
{
IsValidated = true;
}
}
catch
{
}
}
public byte[] Resize(HttpPostedFileWrapper file, int tgtWidth, int tgtHeight)
{
byte[] bytes = new byte[file.ContentLength];
file.InputStream.Read(bytes, 0, file.ContentLength);
file.InputStream.Close(); // close the file stream.
// Down-sample if needed from current byte array to max 250x250 Jpeg
byte[] resized = Helpers.ImageResizer.ResizeImage(bytes, tgtWidth, tgtHeight, ResizeOptions.MaxWidthAndHeight, ImageFormat.Jpeg);
return resized;

}

Fill in Word template and save as pdf using openxml and openoffice

I am trying to fill a word document with data from an XML. I am using openXML to fill the document, which works great and save it as .docx. The thing is I have to open Word and save the document as an .odt and then use the OpenOffice SDK to open the .docx and save it as a pdf. When I don't save the .docx as .odt, the formatting is off.
What I need to be able to do is be able to either convert the .docx to .odt or save it originally as .odt.
Here is what I have right now:
static void Main()
{
string documentText;
XmlDocument xmlDoc = new XmlDocument(); // Create an XML document object
xmlDoc.Load("C:\\Cache\\MMcache.xml"); // Load the XML document from the specified file

XmlNodeList PatientSignatureImg = xmlDoc.GetElementsByTagName("PatientSignatureImg");
byte[] byteArray = File.ReadAllBytes("C:\\Cache\\TransportationRunReporttemplate.docx");
using (MemoryStream stream = new MemoryStream())
{
stream.Write(byteArray, 0, (int)byteArray.Length);
using (WordprocessingDocument wordDoc = WordprocessingDocument.Open(stream, true))
{
using (StreamReader reader = new StreamReader(wordDoc.MainDocumentPart.GetStream()))
{
documentText = reader.ReadToEnd();
}
using (StreamWriter writer = new StreamWriter(wordDoc.MainDocumentPart.GetStream(FileMode.Create)))
{
writer.Write(documentText);
}
}
// Save the file with the new name
File.WriteAllBytes("C:\\Cache\\MYFINISHEDTEMPLATE.docx", stream.ToArray());
}

(r =>

).SingleOrDefault();

Just for information I cannot use anything that uses Interop because word will not be installed the machine. I am using OpenXML and OpenOffice

This is what I would try (details below):
1) try Doc format instead of DocX
2) switch to Libre Office and try DocX again
2) use the odf-converter to get a better DocX -> ODT conversion.
More details...
There's something called the odf-conveter (opensource) that can convert DocX->ODT which gives you (typically) more accurate DocX->ODT than Open Office. Take a look at odf-conveter-integrator by OONinja for pre-packaged versions.
Also, Libre Office has DocX support ahead of OpenOffice so you might get a better result simply by switching to Libre Office.
A further option is to start from Doc format rather than DocX. In the OpenOffice world that translates much better to ODT and then to PDF.
Hope that helps.

You may try to use Docxpresso to generate your .odt directly from HTML + CSS code and avoid any conversion issue.
Docxpresso is free for non-commercial use.

Colour appears faded in corrected CMYK image

I am compressing a pdf containing a number of images. The below code I got while browsing for the PDF compression. It works fine for RBG format images but in case of CMYK format the images appears with inverted colours (as a negative). Somehow I was able to convert the inverted colours but the image colour got faded.
Please suggest how should I proceed. Thanks in advance.
