print XPS from memory stream - c#

I use c#
I need to print DOCX, I send the docx to server , convert it to XPS and return XPS as memory stream. convert docx by aspose.
At client I use next code:
System.IO.Stream docStream = ...any xps as stream;
Package package = Package.Open(docStream);
//Create URI for Xps Package
//Any Uri will actually be fine here. It acts as a place holder for the
//Uri of the package inside of the PackageStore
string inMemoryPackageName = string.Format("memorystream://{0}.xps", Guid.NewGuid());
Uri packageUri = new Uri(inMemoryPackageName);
//Add package to PackageStore
PackageStore.AddPackage(packageUri, package);
XpsDocument xpsDoc = new XpsDocument(package, CompressionOption.Maximum, inMemoryPackageName);
FixedDocumentSequence fixedDocumentSequence = xpsDoc.GetFixedDocumentSequence();
PrintDialog dlg = new PrintDialog();
XpsDocument xpsDoc = new
dlg.PrintDocument(fixedDocumentSequence .DocumentPaginator, "Document title");
PackageStore.RemovePackage(packageUri);
xpsDoc.Close();
It work excellent with english, but I print documents with hebrew and arabic too. And in hebrew and arabic order of words is correct, but print every word vice versa.
If I write memory stream on disk as XPS and open it , the text is correct.

How to get emoji to appear in the generated PDF using MigraDoc

I'm trying to generate a PDF that contains some emojis but with no success.
To make it simple and reproduce-able here is the code:
Document document = new Document();
Section section = document.AddSection();
Paragraph paragraph = section.AddParagraph();
paragraph.AddFormattedText("👀 😀 💨 ♡", new Font("Segoe UI Emoji"));
PdfDocumentRenderer pdfRenderer = new PdfDocumentRenderer(true);
pdfRenderer.Document = document;
pdfRenderer.RenderDocument();
var memoryStream = new MemoryStream();
var path = Path.GetTempFileName() + ".pdf";
pdfRenderer.PdfDocument.Save(path);
Process.Start(path);
But unfortunately empty rectangles appear instead:
��
This is a known limitation of PDFsharp. Surrogate pairs do not work yet and Unicode chars that require two 16-bit values (above 0xffff) will not show correctly.

iTextSharp to Word

I am using iTextSharp in my MVC application to create a .pdf file, but is there a way to convert it to a .doc file?
public ActionResult Download(int? Id)
{
string FileName = "Test";
var FilePath = Path.Combine(Path.GetTempPath(), "Temp.pdf");
Document UserPDF = new Document();
PdfWriter.GetInstance(UserPDF, new FileStream(FilePath, FileMode.Create));
CreateCv(UserPDF); // This is where the PDF is created
var fs = new FileStream(FilePath, FileMode.Open);
var Bytes = new byte[fs.Length];
fs.Read(Bytes, 0, (int)fs.Length);
fs.Close();
return File(Bytes, "application/pdf", FileName + ".pdf");
}
To put it simply, no. There is no way to convert it to a DOC file using iTextSharp. It only supports the reading and generating of PDF files.
Converting PDF to DOC is possible by using some other third party libraries but there is no solid way of doing it (and preserving formatting / whitespace) at the moment. If you search the web, people suggest creating an image from the PDF and then appending the image to the end of a blank DOC file (which is a major hack).

Export arabic data into pdf asp.net showing error

When I export ARABIC data into pdf.Microsoft adobereader showing error.Adobe reader could not open file because it is either not a supported file.My code is following asp.net c#.Guide me
protected void btnExport_Click(object sender, EventArgs e)
{
Response.ContentType = "application/pdf";
Response.AddHeader("content-disposition", "attachment;filename=TestPage.pdf");
Document doc = new Document(PageSize.LETTER);
doc.Open();
//Sample HTML
StringBuilder stringBuilder = new StringBuilder();
stringBuilder.Append(#"<p>This is a test: <strong>مسندم</strong></p>");
//Path to our font
string arialuniTff = Server.MapPath("~/tradbdo.TTF");
//Register the font with iTextSharp
iTextSharp.text.FontFactory.Register(arialuniTff);
//Create a new stylesheet
iTextSharp.text.html.simpleparser.StyleSheet ST = new iTextSharp.text.html.simpleparser.StyleSheet();
//Set the default body font to our registered font's internal name
ST.LoadTagStyle(HtmlTags.BODY, HtmlTags.FACE, "Traditional Arabic Bold");
//Set the default encoding to support Unicode characters
ST.LoadTagStyle(HtmlTags.BODY, HtmlTags.ENCODING, BaseFont.IDENTITY_H);
//Parse our HTML using the stylesheet created above
List<IElement> list = HTMLWorker.ParseToList(new StringReader(stringBuilder.ToString()), ST);
//Loop through each element, don't bother wrapping in P tags
foreach (var element in list)
{
doc.Add(element);
}
doc.Close();
Response.Write(doc);
Response.End();
}
I found the following article which shows how to correctly export and display Arabic content via the iTextSharp library: http://geekswithblogs.net/JaydPage/archive/2011/11/02/using-itextsharp-to-correctly-display-hebrew--arabic-text-right.aspx.
Here is the code sample that you can try:
using iTextSharp.text;
using iTextSharp.text.pdf;
using System.Text.RegularExpressions;
using System.IO;
using System.Diagnostics;
public void WriteDocument()
{
//Declare a itextSharp document
Document document = new Document(PageSize.A4);
//Create our file stream and bind the writer to the document and the stream
PdfWriter writer = PdfWriter.GetInstance(document, new FileStream(#"C:\Test.Pdf", FileMode.Create));
//Open the document for writing
document.Open();
//Add a new page
document.NewPage();
//Reference a Unicode font to be sure that the symbols are present.
BaseFont bfArialUniCode = BaseFont.CreateFont(#"C:\ARIALUNI.TTF", BaseFont.IDENTITY_H, BaseFont.EMBEDDED);
//Create a font from the base font
Font font = new Font(bfArialUniCode, 12);
//Use a table so that we can set the text direction
PdfPTable table = new PdfPTable(1);
//Ensure that wrapping is on, otherwise Right to Left text will not display
table.DefaultCell.NoWrap = false;
//Create a regex expression to detect hebrew or arabic code points
const string regex_match_arabic_hebrew = #"[\u0600-\u06FF,\u0590-\u05FF]+";
if (Regex.IsMatch("مسندم", regex_match_arabic_hebrew, RegexOptions.IgnoreCase))
{
table.RunDirection = PdfWriter.RUN_DIRECTION_RTL;
}
//Create a cell and add text to it
PdfPCell text = new PdfPCell(new Phrase("مسندم", font));
//Ensure that wrapping is on, otherwise Right to Left text will not display
text.NoWrap = false;
//Add the cell to the table
table.AddCell(text);
//Add the table to the document
document.Add(table);
//Close the document
document.Close();
//Launch the document if you have a file association set for PDF's
Process AcrobatReader = new Process();
AcrobatReader.StartInfo.FileName = #"C:\Test.Pdf";
AcrobatReader.Start();
}
The iTextSharp.text.Document is a class used to help bridge human concepts like Paragraph and Margin into PDF concepts. The bridge part is important. It is not a PDF file in any way so it should never be treated as a PDF. Doing so would be like treating System.Drawing.Graphics as if it were an image. This leads to one of your problems on the second to last line of code that tries to treat the Document as if it were a PDF by sending it directly to the output stream:
//This won't work
Response.Write(doc);
You will find many, many tutorials out there that do this and they are all wrong. Fortunately (or unfortunately), PDF is forgiving and allows junk data at the end so only a handful of PDF fail and people assume there was some other problem.
Your other problem is that you are missing a PdfWriter. If Document is the bridge, PdfWriter is the actual construction worker that puts that PDF together. It, however, is also not a PDF. Instead, it needs to be bound to a stream like a file, in-memory or the HttpResponse.OutputStream.
Below is some code that shows this off. I very strongly recommend separating your PDF logic from your ASPX logic. Do all of you PDF stuff first and get an actual "something" that represents a PDF, then do something with it.
At the beginning we declare a byte array that we'll fill in later. Next we create a System.IO.MemoryStream that will be used to write the PDF to. After creating the Document we then create a PdfWriter that's bound to the Document and our stream. Your internal code is the same and although I didn't test it it appears correct. Right before we're done with our MemoryStream we grab the active bytes into our byte array. Lastly we use the BinaryWrite() method to send our raw binary PDF to the requesting client.
//At the end of this bytes will hold a byte array representing an actual PDF file
Byte[] bytes;
//Create a simple in-memory stream
using (var ms = new MemoryStream()){
using (var doc = new Document()) {
//Create a new PdfWriter bound to our document and the stream
using (var writer = PdfWriter.GetInstance(doc, ms)) {
doc.Open();
//This is unchanged from the OP's code
//Sample HTML
StringBuilder stringBuilder = new StringBuilder();
stringBuilder.Append(#"<p>This is a test: <strong>مسندم</strong></p>");
//Path to our font
string arialuniTff = Server.MapPath("~/tradbdo.TTF");
//Register the font with iTextSharp
iTextSharp.text.FontFactory.Register(arialuniTff);
//Create a new stylesheet
iTextSharp.text.html.simpleparser.StyleSheet ST = new iTextSharp.text.html.simpleparser.StyleSheet();
//Set the default body font to our registered font's internal name
ST.LoadTagStyle(HtmlTags.BODY, HtmlTags.FACE, "Traditional Arabic Bold");
//Set the default encoding to support Unicode characters
ST.LoadTagStyle(HtmlTags.BODY, HtmlTags.ENCODING, BaseFont.IDENTITY_H);
//Parse our HTML using the stylesheet created above
List<IElement> list = HTMLWorker.ParseToList(new StringReader(stringBuilder.ToString()), ST);
//Loop through each element, don't bother wrapping in P tags
foreach (var element in list) {
doc.Add(element);
}
doc.Close();
}
}
//Right before closing the MemoryStream grab all of the active bytes
bytes = ms.ToArray();
}
//We now have a valid PDF and can do whatever we want with it
//In this case, use BinaryWrite to send it directly to the requesting client
Response.ContentType = "application/pdf";
Response.AddHeader("content-disposition", "attachment;filename=TestPage.pdf");
Response.BinaryWrite(bytes);
Response.End();

Load XPS to documentviewer from embedded resource

i am trying to make help for my application. I have xps documents which i am loading to documentviewer. These files are embedded in resource file.
I am able to access these as bytearray.
For example
Properties.Resources.help_sudoku_methods_2
returns byte[]
However, documentviewer cant read it and requires fixeddocumentsequence.
So i create memory stream from bytearray, then xpsdocument and then fixeddocumentsequence like this:
private void loadDocument(byte[] sourceXPS)
{
MemoryStream ms = new MemoryStream(sourceXPS);
const string memoryName = "memorystream://ms.xps";
Uri memoryUri = new Uri(memoryName);
try
{
PackageStore.RemovePackage(memoryUri);
}
catch (Exception)
{ }
Package package = Package.Open(ms);
PackageStore.AddPackage(memoryUri, package);
XpsDocument xps = new XpsDocument(package, CompressionOption.SuperFast, memoryName);
FixedDocumentSequence fixedDocumentSequence = xps.GetFixedDocumentSequence();
doc.Document = fixedDocumentSequence;
}
This is very unclean aproach and also doesnt work if there are images in files - instead of images in new documents displays images from first loaded doc.
Is there any cleaner way to load XPS from embedded resources to documentviewer? or do i need somethink like copy file from resources to application directory and load from here and not memorystream? Thank you.
why dont you write file to system temp folder and then read from there.
Stream ReadStream = System.Reflection.Assembly.GetExecutingAssembly().GetManifestResourceStream("file1.xps");
string tempFile = Path.GetTempPath()+"file1.xps";
FileStream WriteStream = new FileStream(tempFile, FileMode.Create, FileAccess.Write);
ReadStream.CopyTo(WriteStream);
WriteStream.Close();
ReadStream.Close();
// Read tempFile INTO memory here and then
File.Delete(tempFile);

Extract a single page from an XPS document

I need to split an existing XPS Document and create a new XPS Document with only one page of the original one. I tried to copy the document and delete pages from the copied document, but that's very slow. Is there a more efficient way to do this? In C# please.
Thanks.
Resolved:
public void Split(string originalDocument, string detinationDocument)
{
using (Package package = Package.Open(originalDocument, FileMode.Open, FileAccess.Read))
{
using (Package packageDest = Package.Open(detinationDocument))
{
string inMemoryPackageName = "memorystream://miXps.xps";
Uri packageUri = new Uri(inMemoryPackageName);
PackageStore.AddPackage(packageUri, package);
XpsDocument xpsDocument = new XpsDocument(package, CompressionOption.Maximum, inMemoryPackageName);
XpsDocument xpsDocumentDest = new XpsDocument(packageDest, CompressionOption.Normal, detinationDocument);
var fixedDocumentSequence = xpsDocument.GetFixedDocumentSequence();
DocumentReference docReference = xpsDocument.GetFixedDocumentSequence().References.First();
FixedDocument doc = docReference.GetDocument(false);
var content = doc.Pages[2];
var fixedPage = content.GetPageRoot(false);
var writter = XpsDocument.CreateXpsDocumentWriter(xpsDocumentDest);
writter.Write(fixedPage);
xpsDocumentDest.Close();
xpsDocument.Close();
}
}
}
Open the XpsDocument
Create the destination XpsDocument (same method)
Get the FixedDocumentSequece from the first XpsDocument
Get the first FixedDocument from the sequence.
Get the first PageContent from the Pages property
Get the FixedPage from the Child property of the PageContent
Get the XpsDocumentWriter from the second XpsDocument
Write the FixedPage
Easy.
As noted by Christopher Currens, it may be necessary to use PageContent.GetPageRoot instead of Child in step 6.
Thank you, it can help a lot people looking for a workaround against limitation of Xps printing which ignores PrintTicket defined at page level.
