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?
My employer blocks many sites and although Google is not blocked, some of the results are.

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.

I have implemented the code but the problem is I am able to combine only one image into a single pdf but I want to combine multiple images into a single pdf. My code is:
public void ImagesToPdf(string[] imagepaths, string pdfpath)
{
using (var ms = new MemoryStream())
{
var srcImage = new Bitmap(imagepaths[0].ToString());
iTextSharp.text.Rectangle pageSize = new iTextSharp.text.Rectangle(0, 0, srcImage.Width, srcImage.Height);
var document = new iTextSharp.text.Document(pageSize, 0, 0, 0, 0);
iTextSharp.text.pdf.PdfWriter.GetInstance(document, ms).SetFullCompression();
document.Open();
var image = iTextSharp.text.Image.GetInstance(imagepaths[0].ToString());
document.Add(image);
document.Close();
File.WriteAllBytes(pdfpath, ms.ToArray());
}
}
Any suggestions will be of great help. Thank you
I have finally figured out how to do this task.

{
Document doc = new Document();
doc.SetPageSize(PageSize.A4);
var ms = new System.IO.MemoryStream();
{
PdfCopy pdf = new PdfCopy(doc, ms);
doc.Open();
foreach (string path in filePaths)
{
byte[] data = File.ReadAllBytes(path);
doc.NewPage();
Document imageDocument = null;
PdfWriter imageDocumentWriter = null;
switch (Path.GetExtension(path).ToLower().Trim('.'))
{
case "bmp":
case "gif":
case "jpg":
case "png":
imageDocument = new Document();
using (var imageMS = new MemoryStream())
{
imageDocumentWriter = PdfWriter.GetInstance(imageDocument, imageMS);
imageDocument.Open();
if (imageDocument.NewPage())
{
var image = iTextSharp.text.Image.GetInstance(data);
image.Alignment = Element.ALIGN_CENTER;
image.ScaleToFit(doc.PageSize.Width - 10, doc.PageSize.Height - 10);
if (!imageDocument.Add(image))
{
throw new Exception("Unable to add image to page!");
}
imageDocument.Close();
imageDocumentWriter.Close();
PdfReader imageDocumentReader = new PdfReader(imageMS.ToArray());
var page = pdf.GetImportedPage(imageDocumentReader, 1);
pdf.AddPage(page);
imageDocumentReader.Close();
}
}
break;
case "pdf":
var reader = new PdfReader(data);
for (int i = 0; i < reader.NumberOfPages; i++)
{
pdf.AddPage(pdf.GetImportedPage(reader, i + 1));
}
pdf.FreeReader(reader);
reader.Close();
break;

Once you got the byte array then just just write all bytes into file like this
byte[] document= ImagesToPDF.ConvertIntoSinglePDF(images);
File.WriteAllBytes("cheque.pdf", document);
ASP.NET C# Code Less
string FileNamePdf = PdfFileName.Text;
Document document = new iTextSharp.text.Document(PageSize.A4, 10f, 10f, 10f, 10f);
var output = new FileStream(Path.Combine(ObjData.ParentFolderPath + "\\SaveLocation", FileNamePdf + ".pdf"), FileMode.Create);
var writer = PdfWriter.GetInstance(document, output);
document.Open();
foreach (HttpPostedFile file in FilesToConvert.PostedFiles)
{
Image image = iTextSharp.text.Image.GetInstance(file.InputStream);
image.ScaleAbsolute(575f, 820.25f);
document.Add(image);
writer.NewPage();
}
document.Close();
I have this code that will add a watermark on each page:
string watermarkLocation = AppDomain.CurrentDomain.BaseDirectory + "Watermark.png";
Document document = new Document();
PdfReader pdfReader = new PdfReader(fileLocation);
PdfStamper stamp = new PdfStamper(pdfReader, new FileStream(fileLocation.Replace(".pdf", "_marked.pdf"), FileMode.Create));
iTextSharp.text.Image img = iTextSharp.text.Image.GetInstance(watermarkLocation);
img.ScaleToFit(document.PageSize);
img.SetAbsolutePosition(0, 100);
PdfContentByte waterMark;
for (int page = 1; page <= pdfReader.NumberOfPages; page++)
{
waterMark = stamp.GetOverContent(page);
waterMark.AddImage(img);
}
stamp.FormFlattening = true;
stamp.Close();
return fileLocation.Replace(".pdf", "_marked.pdf");
But on PDFs that have textboxes, the image will go behind the textbox/form. I thought flattening the file will fix this, but it does not work.
I used a full image as a test but the watermark in the end will have transparency.
Here's the final code I'm using. As my comment mentioned, there's basically 2 readers/stamps, one to flatten the file and another to add the watermark.
Flatten file:
private byte[] FlattenPdfFormToBytes(PdfReader reader)
{
var memStream = new MemoryStream();
var stamper = new PdfStamper(reader, memStream) { FormFlattening = true };
stamper.Close();
return memStream.ToArray();
}
Add Watermark (which will call FlattenPdfFormToBytes):
public string AddWatermark(string fileLocation)
{
string watermarkLocation = AppDomain.CurrentDomain.BaseDirectory + "Watermark.png";
Document document = new Document();
PdfReader pdfReader = new PdfReader(fileLocation);
PdfReader pdfFlatten = new PdfReader(FlattenPdfFormToBytes(pdfReader)); // The secret sauce is this!!!
PdfStamper stamp = new PdfStamper(pdfFlatten, new FileStream(fileLocation.Replace(".pdf", "_marked.pdf"), FileMode.Create));
iTextSharp.text.Image img = iTextSharp.text.Image.GetInstance(watermarkLocation);
img.ScaleToFit(document.PageSize);
img.SetAbsolutePosition(0, 100);
PdfContentByte waterMark;
for (int page = 1; page <= pdfFlatten.NumberOfPages; page++)
{
waterMark = stamp.GetOverContent(page);
waterMark.AddImage(img);
}
stamp.Close();
return fileLocation.Replace(".pdf", "_marked.pdf");
}
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 generating a PDF document based on template. The document has multiple pages. The document can have about 5000 pages. When creating the 500-th page I get an overflow RAM (memory). Any idea?
public static void CreateBankBlank2012Year(string pdfTemplatePath, string directoryOutPdf, string nameOutPdf, AnnualReportsFilterParameters filterParametrs, string serverPath)
{
// Get details salary
IEnumerable<SalayDetailsForPdf> dataSalaryDetails = (IEnumerable<SalayDetailsForPdf>) GetSalaryData(filterParametrs);
String fontPath = Path.Combine(serverPath + "\\Fonts", "STSONG.ttf");
Font font = FontFactory.GetFont(fontPath, BaseFont.IDENTITY_H, 8);
using (Document document = new Document())
{
using (PdfSmartCopy copy = new PdfSmartCopy(
document, new FileStream(directoryOutPdf + nameOutPdf, FileMode.Create))
)
{
document.Open();
foreach (var data in dataSalaryDetails)
{
PdfReader reader = new PdfReader(pdfTemplatePath + #"\EmptyTemplateBankBlank_2012.pdf");
using (var ms = new MemoryStream())
{
using (PdfStamper stamper = new PdfStamper(reader, ms))
{
stamper.AcroFields.AddSubstitutionFont(font.BaseFont);
AcroFields form = stamper.AcroFields;
form.SetField("t1_address1", data.Address1);
form.SetField("t1_name", data.NameHieroglyphic);
// Other field ...
stamper.FormFlattening = true;
}
reader = new PdfReader(ms.ToArray());
copy.AddPage(copy.GetImportedPage(reader, 1));
}
}
}
}
}
p.s
I'm trying resolve my problem as follow:
generating empty pages based on template
private static void GeneratePdfFromTemplate(string directoryOutPdf, string nameOutPdf, string pdfTemplatePath, int countPages)
{
using (Document document = new Document())
{
using (PdfSmartCopy copy = new PdfSmartCopy(
document, new FileStream(directoryOutPdf + nameOutPdf, FileMode.Create))
)
{
document.Open();
PdfReader reader = new PdfReader(pdfTemplatePath + #"\EmptyTemplateBankBlank_2012.pdf");
for (int i = 0; i < countPages; i++)
{
copy.AddPage(copy.GetImportedPage(reader, 1));
}
reader.Close();
copy.Close();
}
document.Close();
}
GC.Collect();
}
But after a generating I can't set values to the fields.
I'm found solution for my problem, if anyone else would be interested :
private static void SettingFieltValue(Font font, IEnumerable<SalayDetailsForPdf> dataSalaryDetails, int selectedYear, string directoryOutPdf, string nameOutPdf, string pdfTemplatePath)
{
string pdfTemplate = pdfTemplatePath + #"\EmptyTemplateBankBlank_2012.pdf";
string newFile = directoryOutPdf + nameOutPdf;
var fs = new FileStream(newFile, FileMode.Create);
var conc = new PdfConcatenate(fs, true);
foreach (var data in dataSalaryDetails)
{
var reader = new PdfReader(pdfTemplate);
using (var ms = new MemoryStream())
{
using (PdfStamper stamper = new PdfStamper(reader, ms))
{
stamper.AcroFields.AddSubstitutionFont(font.BaseFont);
AcroFields form = stamper.AcroFields;
form.SetField("t1_name", data.NameHieroglyphic);
//Other field
stamper.FormFlattening = true;
stamper.Close();
}
reader = new PdfReader(ms.ToArray());
ms.Close();
}
conc.AddPages(reader);
reader.Close();
}
conc.Close();
}
The code snippet below returns a corrupt PDF document however if I return mergedDocument instead it always returns a valid PDF. mergedDocument is based on a PDF file i created using Word, whereas completed document is entirely programmatically generated. The code "works" in that it throws no exceptions. Why is iTextSharp creating a corrupt PDF?
byte[] completedDocument = null;
using (MemoryStream streamCompleted = new MemoryStream())
{
using (Document document = new Document())
{
PdfCopy copy = new PdfCopy(document, streamCompleted);
document.Open();
copy.Open();
foreach (var item in eventItems)
{
byte[] mergedDocument = null;
PdfReader reader = new PdfReader(pdfTemplates[item.DataTokens[NotifyTokenType.OrganisationID]]);
using (MemoryStream streamTemplate = new MemoryStream())
{
using (PdfStamper stamper = new PdfStamper(reader, streamTemplate))
{
foreach (var token in item.DataTokens)
{
if (stamper.AcroFields.Fields.Any(fld => fld.Key == token.Key.ToString()))
{
stamper.AcroFields.SetField(token.Key.ToString(), token.Value);
}
}
stamper.FormFlattening = true;
stamper.Writer.CloseStream = false;
}
mergedDocument = new byte[streamTemplate.Length];
streamTemplate.Position = 0;
streamTemplate.Read(mergedDocument, 0, (int)streamTemplate.Length);
}
reader = new PdfReader(mergedDocument);
for (int i = 1; i <= reader.NumberOfPages; i++)
{
document.SetPageSize(PageSize.A4);
copy.AddPage(copy.GetImportedPage(reader, i));
}
}
completedDocument = new byte[streamCompleted.Length];
streamCompleted.Position = 0;
streamCompleted.Read(completedDocument, 0, (int)streamCompleted.Length);
}
}
return completedDocument;
You need to close the document and copy objects to flush the PDF writing buffer. This, however, causes some problems when trying to read the stream into an array. The fix for that is to use the ToArray() method of the MemoryStream which still works on closed streams. The changes I made have comments on them.
byte[] completedDocument = null;
using (MemoryStream streamCompleted = new MemoryStream())
{
using (Document document = new Document())
{
PdfCopy copy = new PdfCopy(document, streamCompleted);
document.Open();
copy.Open();
foreach (var item in eventItems)
