I am facing a problem when I try to declare a PageHeight on an XPS Document.
My code so far looks like this:
private FixedDocumentSequence GetDocument(DocumentPaginator paginator)
{
FixedDocumentSequence document = null;
string tempFileName = System.IO.Path.GetTempFileName();
File.Delete(tempFileName);
using (var xpsDocument = new XpsDocument(tempFileName, FileAccess.ReadWrite, CompressionOption.NotCompressed))
{
var writer = XpsDocument.CreateXpsDocumentWriter(xpsDocument);
var printTicket = new PrintTicket
{
PageMediaSize = new PageMediaSize(PageMediaSizeName.ISOA4, paginator.PageSize.Width, paginator.PageSize.Height),
PageBorderless = PageBorderless.Borderless,
PageMediaType = PageMediaType.None,
};
writer.Write(paginator, printTicket);
//paginator.PageSize.Height = 1122
var d = xpsDocument.GetFixedDocumentSequence();
//d.DocumentPaginator.PageSize.Height = 1056
document = d;
}
return document;
}
The Problem is that I am declaring a PageSize Height of 1122 which I am getting from this code:
var pd = new PrintDialog();
var sz = new Size(pd.PrintableAreaWidth, pd.PrintableAreaHeight);
but when I look into the property
d.DocumentPaginator.PageSize.Height
I can see that the Height is 1056, this height happens to be the Height of the NorthAmericanLetter Page format height, I am already specifying a specific printTicket with an explicit PageMediaSize what else could be wrong?
Edit:
Here is my edited code, but this give the same result:
private FixedDocumentSequence GetDocument(DocumentPaginator paginator)
{
FixedDocumentSequence document = null;
string oldTempFileName = System.IO.Path.GetTempFileName();
File.Delete(oldTempFileName);
XpsDocument oldXpsDocument;
using (oldXpsDocument = new XpsDocument(oldTempFileName, FileAccess.ReadWrite, CompressionOption.NotCompressed))
{
var writer = XpsDocument.CreateXpsDocumentWriter(oldXpsDocument);
var printTicket = new PrintTicket
{
PageMediaSize = new PageMediaSize(PageMediaSizeName.ISOA4, paginator.PageSize.Width, paginator.PageSize.Height),
PageBorderless = PageBorderless.Borderless,
PageMediaType = PageMediaType.None,
};
writer.Write(paginator, printTicket);
}
//string newTempFileName = System.IO.Path.GetTempFileName();
//File.Delete(newTempFileName);
using (var newXpsDocument = new XpsDocument(oldTempFileName, FileAccess.Read, CompressionOption.NotCompressed))
{
var d = newXpsDocument.GetFixedDocumentSequence();
document = d;
}
return document;
}
I looked into the file that got created with the first using block and I still can see that the height of the pages is 1056, output of the 1.fpage file:
<FixedPage
xmlns="http://schemas.microsoft.com/xps/2005/06" xmlns:x="http://schemas.microsoft.com/xps/2005/06/resourcedictionary-key"
xml:lang="und"
Width="816" Height="1056">
<FixedPage.Resources>
<ResourceDictionary>
<LinearGradientBrush x:Key="b0" StartPoint="33,0" EndPoint="33,23" ColorInterpolationMode="SRgbLinearInterpolation" MappingMode="Absolute" SpreadMethod="Pad">
Edit2:
Found the a solution for my problem.
In my DocumentPaginator I had to override the GetPage Method and there I return a new DocumentPage(visual), this constructor has an overload that lets me set the PageSize only if I set it there its setting the PageSizes correctly.
http://msdn.microsoft.com/en-us/library/system.windows.documents.documentpage(v=vs.110).aspx
http://msdn.microsoft.com/en-us/library/ms597306(v=vs.110).aspx
My previous code:
public override DocumentPage GetPage(int pageNumber)
{
// create page element (PageTemplate is a custom usercontrol that can hold content)
var page = new PageTemplate(this, pageNumber + 1);
// arrange the elements on the page
page.Arrange(new Rect(0, 0, PageSize.Width, PageSize.Height));
// return new document page
return new DocumentPage(page);
}
Now with the second contructor:
public override DocumentPage GetPage(int pageNumber)
{
// create page element (PageTemplate is a custom usercontrol that can hold content)
var page = new PageTemplate(this, pageNumber + 1);
// arrange the elements on the page
page.Arrange(new Rect(0, 0, PageSize.Width, PageSize.Height));
// return new document page
return new DocumentPage(page, PageSize, new Rect(0, 0, 10, 10), new Rect());
}
The problem is that you're expecting the xpsDocument to have the same dimensions of the file that you created.
When you create an XpsDocument, its going to have a default FixedDocumentSequence. Since you're creating an XpsDocument, and not opening one, you're getting the default fixed document sequence, which is why you are seeing 1056 as the height--default that is the default.
However, if you look at the code example at the bottom of FixedDocumentSequence, you'll see LoadDocumentViewer, where it replaces an old XpsDocument with a new one.
When you call writer.Write(paginator, printTicket); it will write an XpsDocument to the file you specified using the PrintTicket you provided. Now you need to create an XpsDocument using that file path, and when you open it, you can then get the FixedDocumentSequence of that document and the sizes with match the PrintTicket properties. So in pseudo-code, you should do this:
string fileName = ...
using Create XpsDocument at fileName
Create XpsDocumentWriter
Create and setup PrintTicket
Write to the file using your DocumentPaginator and PrintTicket
using Create XpsDocument reading from fileName
document = opened XpsDocument GetFixedDocumentSequence()
Edit:
Good find in your last edit. I printed an XPS document using MS Word with the A4 sized setting and all the pages come up as 1056 x 816 also. I then created an XPS document using the A3 size and that comes up as 1587.36 x 1122.56. There is clearly something going on internally that we cannot see; my guess is that since the page sizes are similar in dimension, it just uses the 1056 x 816 dimensions? Who really knows... I would suggest filing a bug report to Microsoft.
In the meantime, maybe try to change d.DocumentPaginator.PageSize or even d.PrintTicket objects and try to get the page size to change that way. If there is a way to enumerate the FixedPage's you could change their settings manually too.

I am trying to add multiple signatures with iTextSharp 5.5.13.1.
Only the last signature is valid.
And all previous signatures are invalid with the message:
"Document has been altered or corrupted since it was signed" - 1 Page(s) Modified
I don't necessarily need certified signatures.
I use signature append mode but still can't figure out what modifies the document.
In notepad the first part of document till the second signature seems unchanged.
The code I used is:
private string SignFile(string fileToSign, string certname, float xPercent, float yPercent, int page)
{
string signedFile = fileToSign.Replace(".pdf", ".signed.pdf");
using (PdfReader pdfReader = new PdfReader(fileToSign))
{
int pages = pdfReader.NumberOfPages;
var currentSignaturesCount = pdfReader.AcroFields.GetSignatureNames().Count();
using (FileStream signedPdf = new FileStream(signedFile, FileMode.Create, FileAccess.ReadWrite))
{
string tempDir = Path.Combine(Environment.GetFolderPath(Environment.SpecialFolder.ApplicationData), ".tempfiles");
Directory.CreateDirectory(tempDir);
string tempFileName = Path.Combine(tempDir, Guid.NewGuid().ToString("N") + ".pdf");
if (!File.Exists(tempFileName))
File.Create(tempFileName).Close();
using (PdfStamper pdfStamper = PdfStamper.CreateSignature(pdfReader, signedPdf, '\0', tempFileName, true)) // Append mode
{
// Add signature image
if (page <= pages && page > 0)
{
var pdfContentByte = pdfStamper.GetOverContent(page);
var pageSize = pdfReader.GetPageSize(i);
float pageWidth = pageSize.Width;
float pageHeight = pageSize.Height;
// GenerateStamp() = simplified function that will get a custom bitmap (code not included here)
System.Drawing.Bitmap img = GenerateStamp();
var image = iTextSharp.text.Image.GetInstance(img, true);
image.SetAbsolutePosition(xPercent * pageWidth, pageHeight - yPercent * pageHeight - image.ScaledHeight);
pdfContentByte.AddImage(image);
}
//Also tried adding the image directly to signatureAppearance
//signatureAppearance.SignatureGraphic = image;
//signatureAppearance.SetVisibleSignature(rectangle, page, signatureFieldName);
// and getting the error "Document has been altered or corrupted since it was signed"
PdfSignatureAppearance signatureAppearance = pdfStamper.SignatureAppearance;
signatureAppearance.Reason = "Test";
signatureAppearance.SignDate = DateTime.Now;
signatureAppearance.SignatureRenderingMode = PdfSignatureAppearance.RenderingMode.GRAPHIC;
signatureAppearance.Acro6Layers = false;
//Also tried like this:
//signatureAppearance.CertificationLevel = currentSignaturesCount == 0 ? PdfSignatureAppearance.CERTIFIED_FORM_FILLING_AND_ANNOTATIONS : PdfSignatureAppearance.NOT_CERTIFIED;
// with message: "There have been changes made to this document that invalidate the signature"
// sign document
try
{
X509Certificate2 cert = GetCertificateByName(certname);
Org.BouncyCastle.X509.X509CertificateParser cp = new Org.BouncyCastle.X509.X509CertificateParser();
Org.BouncyCastle.X509.X509Certificate[] chain = new Org.BouncyCastle.X509.X509Certificate[] { cp.ReadCertificate(cert.RawData) };
IExternalSignature externalSignature = new X509Certificate2Signature(cert, "SHA-256");
MakeSignature.SignDetached(signatureAppearance, externalSignature, chain, null, null, null, 0, CryptoStandard.CMS);
}
catch (Exception ex)
{
throw;
}
}
}
}
return signedFile;
}
Any help is appreciated. Thanks
Your code as is adds an image to the static content of a page. That is forbidden to do to a signed file. For details on allowed and disallowed changes to a signed PDF read this answer.
According to your code comments, though, you also tried to alternatively add the image to the signature appearance. That is not forbidden as such. But analyzing the provided example PDFs it becomes apparent that in this attempt additional content streams have been added to the page. Even though they essentially are empty, this is considered a change of page content which is disallowed.
As it turned out, you didn't add the image to the page content in this attempt but you still retrieved the OverContent of the page:
var pdfContentByte = pdfStamper.GetOverContent(page);
This operation already adds extra content streams to the page for the OverContent to come. Strictly speaking, therefore, the method should be named CreateOrGetOverContent instead...
After removing the GetOverContent call signing does not damage the previous signatures anymore.
I am trying to add a sticky note reply to in pdf using iTextSharp. I am able to create a new annotation in the pdf. But i cannot link it as child of an already existing annotation. I copied most of the properties in parent to its child. I copied it by analyzing the properties of a reply, by manually adding a reply from Adobe Reader. What I am missing is the property /IRT. It needs a reference to the parent popup. Like /IRT 16 0 R.
Below is the code i am trying.
private void annotateReplyPdf()
{
string outputFile = #"D:\temp\temp.pdf";
// Creating iTextSharp.text.pdf.PdfReader object to read the Existing PDF Document
using (PdfReader reader = new PdfReader(FILE_NAME))
{
using (FileStream fs = new FileStream(outputFile, FileMode.Create, FileAccess.Write, FileShare.None))
{
// Creating iTextSharp.text.pdf.PdfStamper object to write Data from iTextSharp.text.pdf.PdfReader object to FileStream object
using (PdfStamper stamper = new PdfStamper(reader, fs))
{
//get page 1
PdfDictionary pageDic = reader.GetPageN(1);
//get annotations in page 1
PdfArray pageAnnotsArray = pageDic.GetAsArray(PdfName.ANNOTS);
if (pageAnnotsArray != null)
{
PdfDictionary curAnnotDic = pageAnnotsArray.GetAsDict(0);
PdfArray rect = curAnnotDic.GetAsArray(PdfName.RECT);
Rectangle rectangle = new Rectangle(float.Parse(rect[0].ToString()), float.Parse(rect[1].ToString()), float.Parse(rect[2].ToString()), float.Parse(rect[3].ToString()));
PdfAnnotation newAnnot = new PdfAnnotation(stamper.Writer, rectangle);
newAnnot.Title = "john.conor";
var dtNow = DateTime.Now;
newAnnot.Put(PdfName.C, curAnnotDic.Get(PdfName.C));
newAnnot.Put(PdfName.CONTENTS, new PdfString("Reply using prog"));
newAnnot.Put(PdfName.CREATIONDATE, new PdfDate(dtNow));
// newAnnot.Put(PdfName.IRT, curAnnotDic.); stuck here
newAnnot.Put(PdfName.M, new PdfDate(dtNow));
newAnnot.Put(PdfName.NAME, curAnnotDic.Get(PdfName.NAME));
newAnnot.Put(PdfName.RC, curAnnotDic.Get(PdfName.RC));
newAnnot.Put(PdfName.SUBTYPE, PdfName.TEXT);
newAnnot.Put(PdfName.SUBJECT, curAnnotDic.Get(PdfName.SUBJECT));
stamper.AddAnnotation(newAnnot, 1);
}
}
}
}
}
The methods I have used might not be accurate or efficient, as most of the code were found by trial and error and checking other similar examples(also checking the pdf specification).
Can somebody please fill that code, which does the magic.
note: SO question doesn't provide a code for the answer.
Please take a look at the AddInReplyTo example.
We have a file named hello_sticky_note.pdf that looks like this:
I am going to skip the method to detect the annotation of the sticky note (in your question, you already have this code). In my example, I know that this annotation is the first entry in the /Annots array (the annotation with index 0).
This is how I'm going to add an "in reply to" annotation:
public void manipulatePdf(String src, String dest) throws IOException, DocumentException {
PdfReader reader = new PdfReader(src);
PdfDictionary page = reader.getPageN(1);
PdfArray annots = page.getAsArray(PdfName.ANNOTS);
PdfDictionary sticky = annots.getAsDict(0);
PdfArray stickyRect = sticky.getAsArray(PdfName.RECT);
PdfStamper stamper = new PdfStamper(reader, new FileOutputStream(dest));
PdfWriter writer = stamper.getWriter();
Rectangle stickyRectangle = new Rectangle(
stickyRect.getAsNumber(0).floatValue(), stickyRect.getAsNumber(1).floatValue(),
stickyRect.getAsNumber(2).floatValue(), stickyRect.getAsNumber(3).floatValue()
);
PdfAnnotation replySticky = PdfAnnotation.createText(
writer, stickyRectangle, "Reply", "Hello PDF", true, "Comment");
replySticky.put(PdfName.IRT, annots.getAsIndirectObject(0));
stamper.addAnnotation(replySticky, 1);
stamper.close();
}
Just like you, I get the original annotation (in my code, it's named sticky) and I get the position of that annotation (stickyRect). I create a stickyRectangle object in a slightly different way than you do (my way is better, but that doesn't matter too much) and I use that stickyRectangle to create a new PdfAnnotation named replySticky.
That's what you already have. Now I add the missing part:
replySticky.Put(PdfName.IRT, annots.GetAsIndirectObject(0));
In your code, you add the annotation dictionary, but what you actually need is the reference to that dictionary.
The resulting PDF looks like hello_in_reply_to.pdf:
I have created a custom document paginator that takes a datatable and prints exactly as I need. I would like to do a print preview. I have read all the posts on how to create a xps file in memory and then display it. I just can't get it to work. Here is my code. I am using a MVVM pattern. Please note the line of code _data.DocView=fds; This passes the data to my view model.
PrintDialog dialog = new PrintDialog();
dialog.ShowDialog();
StoreDataSetPaginator paginator = new StoreDataSetPaginator(dt, new Typeface("Calibri"), 8, 96 * 0.75,
new Size(dialog.PrintableAreaWidth, dialog.PrintableAreaHeight));
//this is commented out to attempt the print preview
// dialog.PrintDocument(paginator, "Print out");
MemoryStream ms = new MemoryStream();
Package package = Package.Open(ms, FileMode.Create, FileAccess.ReadWrite);
Uri DocumentUri = new Uri("pack://InMemoryDocument.xps");
PackageStore.AddPackage(DocumentUri, package);
XpsDocument xpsDocument = new XpsDocument(package, CompressionOption.NotCompressed,
DocumentUri.AbsoluteUri);
XpsDocumentWriter writer = XpsDocument.CreateXpsDocumentWriter(xpsDocument);
writer.Write(paginator);
IDocumentPaginatorSource fds = xpsDocument.GetFixedDocumentSequence();
_data.DocView = fds;
PrintPreviewConduit prntv = new PrintPreviewConduit();
prntv.Show();
Now here is my view model:
private IDocumentPaginatorSource _docView;
public IDocumentPaginatorSource DocView
{
get { return _docView; }
set
{
_docView = value;
OnPropertyChanged("DocView");
}
}
And finally my XAML:
<Grid>
<DocumentViewer Name="docview" Document="{Binding DocView}"/>
</Grid>
I entered a break point in my ViewModel at "public IDocumentPaginatorSource DocView" and when I roll my mouse over it I get "System.Windows.Documents.FixedDocumentSequence. Not sure what i should be getting. I spent a good while now and any help would be greatly appreciated.

Well I feel stupid. I did not set the new window's datacontext to my view model. Now everything works!!!!
PrintPreviewConduit prntv = new PrintPreviewConduit();
prntv.DataContext = _data;
_data.DocView = fds;
prntv.Show();
I have an application that uses itextsharp to fill PDF form fields.
I got new requirement from the customer to allow underlining the fields values.
I have read many posts including answers to questions in this site but I could't figure out a way to do it.
Current my code does the following:
Creates a PDFStamper instance
Get the form fields using stamper.AcroFields property
Set the field value using the AcroFields.SetFieldRichValue() method.
But when I am opening the PDF the field is empty.
I verified that the field is set as rich text in the PDF itself.
Any idea what I am doing wrong ?
Here is a snnipest of my code:
FileStream stream = File.Open(targetFile, FileMode.Create);
var pdfStamper = new PdfStamper(new PdfReader(sourceFile), stream);
// Iterate the fields in the PDF
foreach (var fieldName in pdfStamper.AcroFields.Fields.Keys)
{
// Get the field value of the current field
var fieldValue = "<?xml version=\"1.0\"?><body xmlns=\"http://www.w3.org/1999/xtml\" xmlns:xfa=\"http://www.xfa.org/schema/xfa-data/1.0/\" xfa:contentType=\"text/html\" xfa:APIVersion=\"Acrobat:8.0.0\" xfa:spec=\"2.4\"><p style=\"text-align:left\"><b><i>Here is some bold italic text</i></b></p><p style= \"font-size:16pt\">This text uses default text state parameters but changes the font size to 16.</p></body>"
// Set the field value
if (String.IsNullOrEmpty(fieldValue) == false)
{
pdfStamper.AcroFields.SetFieldRichValue(key, fieldValue);
}
}
Edit:
I have revised my code based on Mark Storer's post to a question (http://stackoverflow.com/questions/1454701/adding-rich-text-to-an-acrofield-in-itextsharp). The new code is:
// Create reader to read the source file
var reader = new PdfReader(sourceFile);
// Create a stream for the generated file
var stream = File.Open(targetFile, FileMode.Create);
// Create stamper to generate the new file
var pdfStamper = new PdfStamper(reader, stream);
// Field name and value
var fieldName = "myfield";
var fieldValue = "<?xml version=\"1.0\"?><body xfa:APIVersion=\"Acroform:2.7.0.0\" xfa:spec=\"2.1\" xmlns=\"http://www.w3.org/1999/xhtml\" xmlns:xfa=\"http://www.xfa.org/schema/xfa-data/1.0/\"><p dir=\"ltr\" style=\"margin-top:0pt;margin-bottom:0pt;font-family:Helvetica;font-size:12pt\"><b>write line1 bold</b></p</body>";
// Output stream for the temporary file that should contain the apearance of the field
var msOutput = new FileStream(#"d:\temp.pdf", FileMode.Create);
// string reader to read the field value
var textReader = new StringReader(fieldValue);
// Create new document
var document = new Document(pdfStamper.AcroFields.GetFieldPositions(fieldName)[0].position);
// writer for the new doucment
var writer = PdfWriter.GetInstance(document, msOutput);
// Open the document
document.Open();
// Get elements to append to the doucment
var list = HTMLWorker.ParseToList(textReader, null);
// Append elements to the doucment
foreach (var element in list)
{
document.Add(element);
}
// close the documnet
document.Close();
// Append push button that contains the generated content as its apearance
// this approach is based on the suggestion from Mark storer that can be found in:
// http://stackoverflow.com/questions/1454701/adding-rich-text-to-an-acrofield-in-itextsharp
var button = new PushbuttonField(pdfStamper.Writer, pdfStamper.AcroFields.GetFieldPositions(fieldName)[0].position, fieldName + "_")
{
Layout = PushbuttonField.LAYOUT_ICON_ONLY,
BackgroundColor = null,
Template = pdfStamper.Writer.GetImportedPage(new PdfReader(targetFile, 1)
};
pdfStamper.AddAnnotation(button.Field, 1);
pdfStamper.FormFlattening = true;
pdfStamper.Close();
pdfStamper.Dispose();
But the problem now is that the temporary document contains no content....
Any ideas ?
There's a lot of code above, almost 400 lines. In the future, try to distill everything down to a very simple and reproducible test case.
When using SetFieldRichValue you also need to set the PdfStamper's AcroFields.GenerateAppearances property to false:
stamper.AcroFields.GenerateAppearances = false;
You can read more about this here along with some caveats and other workarounds.
I managed to resolve it with little trick - I used Anchor (hyperling) element inside ColumnText element and position it above the form field. The anchor is displayed with underline by default. In order to avoid the hand marker when the user hover the mouse on the anchor, I set the "Reference" property of the anchor to null.
Here is the code I used:
// Create reader
var reader = new PdfReader(sourceFilePathAndName);
// Create stream for the target file
var stream = File.Open(targetFilePathAndName, FileMode.Create);
// Create the stamper
var pdfStamper = new PdfStamper(reader, stream);
const string fieldName = "MyField";
// Get the position of the field
var targetPosition = pdfStamper.AcroFields.GetFieldPositions(fieldName)[0].position;
// Set the font
var fontNormal = FontFactory.GetFont("Arial", 16, Font.UNDERLINE, BaseColor.BLACK);
// Create the anchor
var url = new Anchor("some default text", fontNormal) { Reference = null };
// Create the element that will contain the anchor and allow to position it anywhere on the document
var data = new ColumnText(pdfStamper.GetOverContent(1));
// Add the anchor to its container
data.SetSimpleColumn(url, targetPosition.Left, targetPosition.Bottom, targetPosition.Right, targetPosition.Top, 0, 0);
// Write the content to the document
data.Go();
pdfStamper.FormFlattening = true;
pdfStamper.Close();
pdfStamper.Dispose();
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.
