I need to split a pdf and I have using this code:
using iTextSharp.text;
using iTextSharp.text.pdf;
private static void PDF_ExtractPages(string pdfFilePath, string outputPath)
{
int pageNameSuffix = 0;
// Intialize a new PdfReader instance with the contents of the source Pdf file:
//PdfReader reader = new PdfReader(pdfFilePath);
using (PdfReader reader = new PdfReader(pdfFilePath))
{
FileInfo file = new FileInfo(pdfFilePath);
string pdfFileName = file.Name.Substring(0, file.Name.LastIndexOf(".")) + "-";
for (int pageNumber = 1; pageNumber <= reader.NumberOfPages; pageNumber++)
{
pageNameSuffix++;
string newPdfFileName = string.Format(pdfFileName + "{0}", pageNameSuffix);
Document document = new Document();
PdfCopy copy = new PdfCopy(document, new FileStream(outputPath + "\\" + newPdfFileName + ".pdf", FileMode.Create));
document.Open();
copy.AddPage(copy.GetImportedPage(reader, pageNumber));
document.Close();
copy.Close();
}
}
}
and I get this error on line:
using (PdfReader reader = new PdfReader(pdfFilePath))
type used in a using statement must be implicitly convertible to 'System.IDisposable'
if I remove the using with this code:
PdfReader reader = new PdfReader(pdfFilePath);
the code work but not dispose reader object, and when I try to open a PDF I get a message like: "this document is open by another user".
There is a way to dispose PdfReader and all inside code ?
Thanks !
That's why it doesn't implement IDisposable.
You can use a try-catch block which is a equivalent way.
PdfReader reader = null;
try
{
reader = new PdfReader(pdfFilePath);
// Some code here
}
catch (Exception)
{
// Take some action.
}
finally
{
reader.Dispose();
}

I have a C# .NET program running in Visual Studio. Its function is to merge PDF files together based on their file names.
It works fine for the first 12 or so PDFs but then suddenly exits with code 0 at a certain point. I am not using multi-threading and the PDF library I am using is iTextSharp.
public static string MergePDFs(List<string> fileNames, ref string targetPdf)
{
string merged = "";
using (FileStream stream = new FileStream(targetPdf, FileMode.Create))
{
Document document = new Document();
PdfCopy pdf = new PdfCopy(document, stream);
PdfReader reader = null;
try
{
document.Open();
foreach (var file in fileNames)
{
reader = new PdfReader(file);
pdf.AddDocument(reader);
reader.Close();
}
}
catch (Exception)
{
// merged = "false";
if (reader != null) reader.Close();
}
finally
{
if (document != null)
{
Console.WriteLine("Closing document.");
document.Close(); // exits here
Console.WriteLine("Document closed.");
}
}
}
return merged;
}
The output in the debugger is:
...
Closing document.
The program has exited with code 0 (0x0)
Printed out the exception via the catch block but it was never reached. The try block executed successfully. Removing the try/catch/finally blocks 'fixed' the issue.
This is only a partial fix as there is no longer a way to handle errors now.
public static string MergePDFs(List<string> fileNames, ref string targetPdf)
{
string merged = "";
using (FileStream stream = new FileStream(targetPdf, FileMode.Create))
{
Document document = new Document();
PdfCopy pdf = new PdfCopy(document, stream);
PdfReader reader = null;
document.Open();
foreach (var file in fileNames)
{
reader = new PdfReader(file);
pdf.AddDocument(reader);
reader.Close();
}
document.Close();
}
return merged;
}
I want to cut out all pages of a PDF file that contain a special string (splittag). Until now I have this code but it just gives out all pages of the source PDF. So whats wrong with it? I iterate trough the Pages of the source PDF and check if the actual page contains the splittag, then create a new PDF using it for pagenumber. Would be great if someone could help. Thank you!
iTextSharp.text.PdfReader reader = new iTextSharp.text.PdfReader(textBox3.Text);
string splittag = textBox2.Text;
StringBuilder text = new StringBuilder();
for (int i = 1; i <= reader.NumberOfPages; i++)
{
if(PdfTextExtractor.GetTextFromPage(reader, i, new SimpleTextExtractionStrategy()).ToString().Contains(splittag)) ;
{
richTextBox1.Text = PdfTextExtractor.GetTextFromPage(reader, i, new SimpleTextExtractionStrategy());
Document document = new Document();
PdfCopy copy = new PdfCopy(document, new FileStream(textBox5.Text + "\\" + i + ".pdf", FileMode.Create));
document.Open();
copy.AddPage(copy.GetImportedPage(reader, i));
document.Close();
}
}
I would use following code:
public static List<Integer> determineSplits(String fileName) throws FileNotFoundException, IOException
{
PdfDocument pdfDocument = new PdfDocument(new PdfReader(fileName));
List<Integer> splitPages = new ArrayList<>();
for(int i=1;i<=pdfDocument.getNumberOfPages();i++) {
String pageTxt = PdfTextExtractor.getTextFromPage(pdfDocument.getPage(i));
if(pageTxt.contains("LoremIpsum"))
{
splitPages.add(1);
}
}
pdfDocument.close();
}
This generates a list of pages that need to be included.
Then you can use iText code to separate out the pages you want using
public List<PdfPage> PdfDocument::copyPagesTo(int pageFrom,
int pageTo,
PdfDocument toDocument,
IPdfPageExtraCopier copier)
I am using this code here now. Works fine and is more easy.
FileInfo file = new FileInfo(textBox2.Text);
using (PdfReader reader = new PdfReader(textBox2.Text))
{
for (int pagenumber = 1; pagenumber <= reader.NumberOfPages; pagenumber++)
{
string filename = System.IO.Path.GetFileNameWithoutExtension(file.Name);
Document document = new Document();
if(PdfTextExtractor.GetTextFromPage(reader, pagenumber, new SimpleTextExtractionStrategy()).Contains("LoremIpsum"))
{
PdfCopy copy = new PdfCopy(document, new FileStream(textBox3.Text + "\\" + filename + pagenumber + ".pdf", FileMode.Create));
document.Open();
copy.AddPage(copy.GetImportedPage(reader, pagenumber));
document.Close();
}
}
}
I am using iTextSharp in asp.net (C#) in order to merge more than one PDf template. There is a functionality of print which prints only data of the template. While merging the templates the fields/Controls which are available in the template is renamed using RenameField Method of iTextSharp.
This implementation has broken the Print functionality. As the Print functionality has been written according to the fields.
For merging Templates, I am using a PDFCopy.
Document document = new Document();
bool flag = true;
using (FileStream fileStream = File.Create(newFile))
{
PdfSmartCopy copy = new PdfSmartCopy(document, fileStream);
PdfReader reader;
MemoryStream baos;
for (int i = 0; i < loopCount; i++)
{
reader = new PdfReader(pdfTemplate);
baos = new MemoryStream();
stamper = new PdfStamper(reader, baos);
AcroFields pdfDoc = stamper.AcroFields;
BuildData(datarow,pdfDoc, obj)
renameFields(reader);
stamper.FormFlattening = false;
stamper.Close();
reader = new PdfReader(baos.ToArray());
copy.AddPage(copy.GetImportedPage(reader, 1));
}
document.Close();
strFileName = newFile;
}
private static void renameFields(PdfReader pdfReader)
{
string prepend = String.Format("_{0}", counter++);
foreach (KeyValuePair<string, AcroFields.Item> de in pdfReader.AcroFields.Fields)
{
pdfReader.AcroFields.RenameField(de.Key.ToString(), prepend + de.Key.ToString());
}
}
Edit1: This is the solution i found in itextsharp doc,BUT it's not working
"Using PdfCopy with documents
that have named destinations is one of these exceptions. All annotations, such
as link annotations, are kept with PdfCopy, but they no longer work for links to local
named destinations. There is a workaround for this problem."
PdfReader[] readers = {
new PdfReader(LinkActions.RESULT2),
new PdfReader(LinkActions.RESULT1) };
Document document = new Document();
PdfCopy copy =
new PdfCopy(document, new FileOutputStream(RESULT1));
document.open();
int n;
for (int i = 0; i < readers.length; i++) {
readers[i].consolidateNamedDestinations();
n = readers[i].getNumberOfPages();
for (int page = 0; page < n; ) {
copy.addPage(copy.getImportedPage(readers[i], ++page));
}
}
The forms no longer work because you have forgotten to add a single line: copy.setMergeFields();
See the MergeForms2 example:
public void manipulatePdf(String src, String dest) throws IOException, DocumentException {
Document document = new Document();
PdfCopy copy = new PdfSmartCopy(document, new FileOutputStream(dest));
copy.setMergeFields();
document.open();
List<PdfReader> readers = new ArrayList<PdfReader>();
for (int i = 0; i < 3; ) {
PdfReader reader = new PdfReader(renameFields(src, ++i));
readers.add(reader);
copy.addDocument(reader);
}
document.close();
for (PdfReader reader : readers) {
reader.close();
}
}
public byte[] renameFields(String src, int i) throws IOException, DocumentException {
ByteArrayOutputStream baos = new ByteArrayOutputStream();
PdfReader reader = new PdfReader(src);
PdfStamper stamper = new PdfStamper(reader, baos);
AcroFields form = stamper.getAcroFields();
Set<String> keys = new HashSet<String>(form.getFields().keySet());
for (String key : keys) {
form.renameField(key, String.format("%s_%d", key, i));
}
stamper.close();
reader.close();
return baos.toByteArray();
}
It seems that you're also making the assumption that your template consists of only one page:
copy.addPage(copy.getImportedPage(reader, 1));
It is safer to add the document all at once:
copy.addDocument(reader);
Important:
My examples are written in Java. You are working with iTextSharp in C#. You will have to adapt the methods by changing the Java-specific methods into C#-specific properties or methods.
I'm using ITextSharp to split multi-page PDF files into single page files. I also managed to add those single page PDFs to a zip file using MemoryStream.
Now, I need to add password protection to those PDFs using PdfStamper, before adding them into a zip file. But whenever I tried this, an ObjectDisposedException - Cannot access a closed Stream. is being throwed.
Ionic.Zip.ZipFile zipFile = new Ionic.Zip.ZipFile();
int cnt = 0;
try
{
iTextSharp.text.pdf.PdfReader reader = new iTextSharp.text.pdf.PdfReader(new iTextSharp.text.pdf.RandomAccessFileOrArray(sourcePdfPath), new ASCIIEncoding().GetBytes(""));
for (cnt = 1; cnt <= reader.NumberOfPages; cnt++)
{
using (MemoryStream memoryStream = new MemoryStream())
{
using (iTextSharp.text.Document document = new iTextSharp.text.Document())
{
iTextSharp.text.pdf.PdfWriter writer = iTextSharp.text.pdf.PdfWriter.GetInstance(document, memoryStream);
using (PdfStamper stamper = new PdfStamper(reader, memoryStream))
{
stamper.SetEncryption(
null,
Encoding.ASCII.GetBytes("password_here"),
PdfWriter.ALLOW_PRINTING,
PdfWriter.ENCRYPTION_AES_128);
}
memoryStreamForZipFile = new MemoryStream(memoryStream.ToArray());
memoryStreamForZipFile.Seek(0, SeekOrigin.Begin);
}
}
}
zipFile.Save(destinationFolder + "/" + fileName.Replace(".pdf", ".zip"));
reader.Close();
reader.Dispose();
}
catch
{
}
finally
{
GC.Collect();
}
return cnt - 1;
I have removed some codes above for clarity.
If I'll remove the PdfStamper "using" block, the code works just fine. I also tried to juggle the position of PdfStamper to see if I used it in the wrong place.
Am I not using using blocks properly? Or I have to fix some code sequence in here?
You removed some lines that are essential are wrong; for instance: I assume that you are adding a PdfImportedPage to the PdfContentByte of a PdfWriter. If that's so, you are ignoring all the warnings given in the official documentation.
You should replace your code by something like this:
PdfReader reader = new PdfReader(pathToFile);
int n = reader.NumberOfPages;
int cnt;
for (cnt = 1; cnt <= reader.NumberOfPages; cnt++)
{
reader = new PdfReader(pathToFile);
reader.SelectPages(cnt.ToString());
MemoryStream memoryStream = new MemoryStream();
using (PdfStamper stamper = new PdfStamper(reader, memoryStream))
{
stamper.SetEncryption(
null,
Encoding.ASCII.GetBytes("password_here"),
PdfWriter.ALLOW_PRINTING,
PdfWriter.ENCRYPTION_AES_128);
}
reader.Close();
// now do something with the memoryStream.ToArray()
}
As you can see, there is no need to introduce a Document or a PdfWriter object. If you use those classes, you throw away all interactivity that exists in the original pages. You also get into trouble if the page size of the original pages is different from A4.
Note that you can't reuse the PdfReader instance when using PdfStamper. Once you pass a PdfReader instance to a PdfStamper, that instance is tampered.
I looked into iTextSharp and SharpPDF and Report.Net as well as PDFSharp.
None of these open source projects have good documentation OR do not work with VS 2012.
Does anyone have a recommended solution or can show me the documentation?

You can always just create an html page and then convert that to pdf using wkhtmltopdf. This has the benefit of you not having to construct the pdf with a library such as iText. You just make a text file (html) and then pass it to the wkhtmltopdf executable.
See Calling wkhtmltopdf to generate PDF from HTML for more info.
