Crop Pdf from each edge using itextshap

I am trying to crop pdf 5 mm from every edge i.e top,bottom,right and left. I tried with below code
public void TrimPdf(string sourceFilePath, string outputFilePath)
{
PdfReader pdfReader = new PdfReader(sourceFilePath);
float widthTo_Trim = iTextSharp.text.Utilities.MillimetersToPoints(5);
using (FileStream output = new FileStream(outputFilePath, FileMode.Create, FileAccess.Write))
using (PdfStamper pdfStamper = new PdfStamper(pdfReader, output))
{
for (int page = 1; page <= pdfReader.NumberOfPages; page++)
{
Rectangle cropBox = pdfReader.GetCropBox(page);
cropBox.Left += widthTo_Trim;
cropBox.Right += widthTo_Trim;
cropBox.Top += widthTo_Trim;
cropBox.Bottom += widthTo_Trim;
pdfReader.GetPageN(page).Put(PdfName.CROPBOX, new PdfRectangle(cropBox));
}
}
}
By using this code i am Able to Crop only Left and Bottom part. unable to crop top and right side
How can i get desire result ?

This solved my problem by using Below code
public void TrimLeftandRightFoall(string sourceFilePath, string outputFilePath, float cropwidth)
{
PdfReader pdfReader = new PdfReader(sourceFilePath);
float width = (float)GetPDFwidth(sourceFilePath);
float height = (float)GetPDFHeight(sourceFilePath);
float widthTo_Trim = iTextSharp.text.Utilities.MillimetersToPoints(cropwidth);
PdfRectangle rectLeftside = new PdfRectangle(widthTo_Trim, widthTo_Trim, width-widthTo_Trim , height-widthTo_Trim);
using (var output = new FileStream(outputFilePath, FileMode.CreateNew, FileAccess.Write))
{
// Create a new document
Document doc = new Document();
// Make a copy of the document
PdfSmartCopy smartCopy = new PdfSmartCopy(doc, output);
// Open the newly created document
doc.Open();
// Loop through all pages of the source document
for (int i = 1; i <= pdfReader.NumberOfPages; i++)
{
// Get a page
var page = pdfReader.GetPageN(i);
page.Put(PdfName.MEDIABOX, rectLeftside);
var copiedPage = smartCopy.GetImportedPage(pdfReader, i);
smartCopy.AddPage(copiedPage);
}
doc.Close();
}
}

Removing Watermark from a PDF

I had been used the first code create a water mark and removed and it work perfect
private void Form1_Load(object sender, EventArgs e) {
string workingFolder = Environment.GetFolderPath(Environment.SpecialFolder.Desktop);
string startFile = Path.Combine(workingFolder, "StartFile.pdf");
string watermarkedFile = Path.Combine(workingFolder, "Watermarked.pdf");

doc.Open();
for (int i = 1; i <= 5; i++) {
doc.NewPage();
doc.Add(new Paragraph(String.Format("This is page {0}", i)));
}
doc.Close();
}
}
}
//SECTION 2
//Create our watermark on a separate layer. The only different here is that we are adding the watermark to a PdfLayer which is an OCG or Optional Content Group
PdfReader reader1 = new PdfReader(startFile);

//Get the ContentByte object
PdfContentByte cb = stamper.GetUnderContent(i);
//Tell the CB that the next commands should be "bound" to this new layer
cb.BeginLayer(layer);

}
}
}
//SECTION 3
//Remove the layer created above
//First we bind a reader to the watermarked file, then strip out a bunch of things, and finally use a simple stamper to write out the edited reader

this.Close();
}
}
}
but when I used digital sign some time when a I tried to remove the watermark some page lost the information , them I'm would like to used the PdfLayerRemover and I change to C# but when I made this

Adding text to existing multipage PDF document in memorystream using iTextSharp

I am trying to add text to an existing PDF file using iTextSharp. I have been reading many posts, including the popular thread here.
I have some differences:
My PDF are X pages long
I want to keep everything in memory, and never have a file stored on my filesystem
So I tried to modify the code, so it takes in a byte array and returns a byte array. I have come this far:
The code compiles and runs
My out byte array has a different length than my in byte array
My problem:
I cannot see my added text when i later store the modified byte array and open it in my PDF reader
I don't get why. From every StackOverflow post I have seen, I do the same. using the DirectContent, I use BeginText and write a text. However, i cannot see it, no matter how I move the position around.
Any idea what is missing from my code?
public static byte[] WriteIdOnPdf(byte[] inPDF, string str)
{
byte[] finalBytes;
// open the reader
using (PdfReader reader = new PdfReader(inPDF))
{
Rectangle size = reader.GetPageSizeWithRotation(1);
using (Document document = new Document(size))
{
// open the writer
using (MemoryStream ms = new MemoryStream())
{
using (PdfWriter writer = PdfWriter.GetInstance(document, ms))
{
document.Open();
for (var i = 1; i <= reader.NumberOfPages; i++)
{
document.NewPage();
var baseFont = BaseFont.CreateFont(BaseFont.HELVETICA_BOLD, BaseFont.CP1252, BaseFont.NOT_EMBEDDED);
var importedPage = writer.GetImportedPage(reader, i);
var contentByte = writer.DirectContent;
contentByte.BeginText();
contentByte.SetFontAndSize(baseFont, 18);
var multiLineString = "Hello,\r\nWorld!";
contentByte.ShowTextAligned(PdfContentByte.ALIGN_LEFT, multiLineString,100, 200, 0);
contentByte.EndText();
contentByte.AddTemplate(importedPage, 0, 0);
}
document.Close();
ms.Close();
writer.Close();
reader.Close();
}
finalBytes = ms.ToArray();
}
}
}
return finalBytes;
}

The code below shows off a full-working example of creating a PDF in memory and then performing a second pass, also in memory. It does what #mkl says and closes all iText parts before trying to grab the raw bytes from the stream. It also uses GetOverContent() to draw "on top" of the previous pdf. See the code comments for more details.
//Bytes will hold our final PDFs
byte[] bytes;
//Create an in-memory PDF
using (var ms = new MemoryStream()) {
using (var doc = new Document()) {
using (var writer = PdfWriter.GetInstance(doc, ms)) {
doc.Open();
//Create a bunch of pages and add text, nothing special here
for (var i = 1; i <= 10; i++) {
doc.NewPage();
doc.Add(new Paragraph(String.Format("First Pass - Page {0}", i)));
}
doc.Close();
}
}
//Right before disposing of the MemoryStream grab all of the bytes
bytes = ms.ToArray();
}
//Another in-memory PDF
using (var ms = new MemoryStream()) {
//Bind a reader to the bytes that we created above
using (var reader = new PdfReader(bytes)) {
//Store our page count
var pageCount = reader.NumberOfPages;
//Bind a stamper to our reader
using (var stamper = new PdfStamper(reader, ms)) {
//Setup a font to use
var baseFont = BaseFont.CreateFont(BaseFont.HELVETICA_BOLD, BaseFont.CP1252, BaseFont.NOT_EMBEDDED);
//Loop through each page
for (var i = 1; i <= pageCount; i++) {
//Get the raw PDF stream "on top" of the existing content
var cb = stamper.GetOverContent(i);
//Draw some text
cb.BeginText();
cb.SetFontAndSize(baseFont, 18);
cb.ShowText(String.Format("Second Pass - Page {0}", i));
cb.EndText();
}
}
}
//Once again, grab the bytes before closing things out
bytes = ms.ToArray();
}
//Just to see the final results I'm writing these bytes to disk but you could do whatever
var testFile = Path.Combine(Environment.GetFolderPath(Environment.SpecialFolder.Desktop), "test.pdf");
System.IO.File.WriteAllBytes(testFile, bytes);

Get byte array from PdfWriter, writing to a memorystream in iTextSharp

I have a method, which takes in the following:
Byte array, which is a PDF file
A "from" size
A "to" size
The idea is it transforms a PDF file with a specific size, to another size. I want to return a byte array, and want to keep the whole thing in memory.
I create the PdfWriter using a memorystream in the constructor (outPDF), and then does my conversion. After, I want to say outBytes = outPDF.ToArray(); .
I tried putting this code in three places, see place A, B and C in the code. In place A, the length of the memorystream is only 255, which doesn't work. My guess is the doc.Close() has to run first. In place B and C, the stream is closed, and cannot be accessed.
My question is therefore:
How to get a byte array from PdfWriter, writing to a memorystream in iTextSharp
My code:
public static byte[] ConvertPdfSize(byte[] inPDF, LetterSize fromSize, LetterSize toSize)
{
if (fromSize != LetterSize.A4 || toSize != LetterSize.Letter)
{
throw new ArgumentException("Function only supports from size A4 to size letter");
}
MemoryStream outPDF = new MemoryStream();
byte[] outBytes;
using (PdfReader pdfr = new PdfReader(inPDF))
{
using (Document doc = new Document(PageSize.LETTER))
{
Document.Compress = true;
PdfWriter writer = PdfWriter.GetInstance(doc, outPDF);
doc.Open();
PdfContentByte cb = writer.DirectContent;
PdfImportedPage page;
for (int i = 1; i < pdfr.NumberOfPages + 1; i++)
{
page = writer.GetImportedPage(pdfr, i);
cb.AddTemplate(page, PageSize.LETTER.Width / pdfr.GetPageSize(i).Width, 0, 0, PageSize.LETTER.Height / pdfr.GetPageSize(i).Height, 0, 0);
doc.NewPage();
}
// place A
doc.Close();
// place B
}
pdfr.Close();
// place C
}
return new byte[0];
}

Just return your bytes after all of the iTextSharp stuff is done but before discarding the MemoryStream
using(MemoryStream outPDF = new MemoryStream())
{
using (PdfReader pdfr = new PdfReader(inPDF))
{
using (Document doc = new Document(PageSize.LETTER))
{
//...
}
}
return outPDF.ToArray();
}

How to add multiple fpages to fixed document in xps?

My requirement is to create xps document which has 10 pages (say). I am using the following code to create a xps document. Please take a look.
// Create the new document
XpsDocument xd = new XpsDocument("D:\\9780545325653.xps", FileAccess.ReadWrite);
IXpsFixedDocumentSequenceWriter xdSW = xd.AddFixedDocumentSequence();
IXpsFixedDocumentWriter xdW = xdSW.AddFixedDocument();
IXpsFixedPageWriter xpW = xdW.AddFixedPage();
fontURI = AddFontResourceToFixedPage(xpW, #"D:\arial.ttf");
image = AddJpegImageResourceToFixedPage(xpW, #"D:\Single content\20_1.jpg");
StringBuilder pageContents = new StringBuilder();
pageContents.Append(ReadFile(#"D:\Single content\20.fpage\20.fpage", i));
xmlWriter = xpW.XmlWriter;
xmlWriter.WriteRaw(pageContents.ToString());
}
xmlWriter.Close();
xpW.Commit();
// Commit the fixed document
xdW.Commit();
// Commite the fixed document sequence writer
xdSW.Commit();
// Commit the XPS document itself
xd.Close();
}
private static string AddFontResourceToFixedPage(IXpsFixedPageWriter pageWriter, String fontFileName)
{
string fontUri = "";
using (XpsFont font = pageWriter.AddFont(false))
{
using (Stream dstFontStream = font.GetStream())
using (Stream srcFontStream = File.OpenRead(fontFileName))
{
CopyStream(srcFontStream, dstFontStream);
// commit font resource to the package file
font.Commit();
}
fontUri = font.Uri.ToString();
}
return fontUri;
}
private static Int32 CopyStream(Stream srcStream, Stream dstStream)
{
const int size = 64 * 1024; // copy using 64K buffers
byte[] localBuffer = new byte[size];
int bytesRead;
Int32 bytesMoved = 0;
// reset stream pointers
srcStream.Seek(0, SeekOrigin.Begin);
dstStream.Seek(0, SeekOrigin.Begin);
// stream position is advanced automatically by stream object
while ((bytesRead = srcStream.Read(localBuffer, 0, size)) > 0)
{
dstStream.Write(localBuffer, 0, bytesRead);
bytesMoved += bytesRead;
}
return bytesMoved;
}
private static string ReadFile(string filePath,int i)
{
FileStream fs = new FileStream(filePath, FileMode.Open, FileAccess.ReadWrite);
StringBuilder sb = new StringBuilder();
using (StreamReader sr = new StreamReader(fs))
{
String line;
// Read and display lines from the file until the end of
// the file is reached.
while ((line = sr.ReadLine()) != null)
{
sb.AppendLine(line);
}
}
string allines = sb.ToString();
//allines = allines.Replace("FontUri=\"/Resources/f7728e4c-2606-4fcb-b963-d2d3f52b013b.odttf\"", "FontUri=\"" + fontURI + "\" ");
//XmlReader xmlReader = XmlReader.Create(fs, new XmlReaderSettings() { IgnoreComments = true });
XMLSerializer serializer = new XMLSerializer();
FixedPage fp = (FixedPage)serializer.DeSerialize(allines, typeof(FixedPage));
foreach (Glyphs glyph in fp.lstGlyphs)
{
glyph.FontUri = fontURI;
}
fp.Path.PathFill.ImageBrush.ImageSource = image;
fs.Close();
string fpageString = serializer.Serialize(fp);
return fpageString;
}
private static string AddJpegImageResourceToFixedPage(IXpsFixedPageWriter pageWriter, String imgFileName)
{
XpsImage image = pageWriter.AddImage("image/jpeg");
using (Stream dstImageStream = image.GetStream())
using (Stream srcImageStream = File.OpenRead(imgFileName))
{
CopyStream(srcImageStream, dstImageStream); // commit image resource to the package file
//image.Commit();
}
return image.Uri.ToString();
}
If you see it, i would have passed single image and single fpage to create a xps document. I want to pass multiple fpages list and image list to create a xps document which has multiple pages..?

You are doing this in the most excruciatingly difficult manner possible. I'd suggest taking the lazy man's route.
Realize that an XpsDocument is just a wrapper on a FixedDocumentSequence, which contains zero or more FixedDocuments, which contains zero or more FixedPages. All these types can be created, manipulated and combined without writing XML.
All you really need to do is create a FixedPage with whatever content on it you need. Here's an example:
static FixedPage CreateFixedPage(Uri imageSource)
{
FixedPage fp = new FixedPage();
fp.Width = 320;
fp.Height = 240;
Grid g = new Grid();
g.HorizontalAlignment = System.Windows.HorizontalAlignment.Center;
g.VerticalAlignment = System.Windows.VerticalAlignment.Center;
fp.Children.Add(g);
Image img = new Image
{
UriSource = imageSource,
};
g.Children.Add(image);
return fp;
}
This is all WPF. I'm creating a FixedPage that has as its root a Grid, which contains an Image that is loaded from the given Uri. The image will be stretched to fill the available space of the Grid. Or, you could do whatever you want. Create a template as a UserControl, send it text to place within itself, whatever.
Next, you just need to add a bunch of fixed pages to an XpsDocument. It's incredibly hard, so read carefully:
public void WriteAllPages(XpsDocument document, IEnumerable<FixedPage> pages)
{
var writer = XpsDocument.CreateXpsDocumentWriter(document);
foreach(var page in pages)
writer.Write(page);
}
And that's all you need to do. Create your pages, add them to your document. Done.
