I have the code for my pdf merge application but I need help on how to make this all work. I need help on the winforms Design. Obviously its just a blank screen right now without the design.
Below you will see my form code which is labeled form1.cs and program.cs which is below
Program.cs
using System;
using System.Collections.Generic;
using System.Linq;
using System.Threading.Tasks;
using System.Windows.Forms;
namespace WindowsFormsApplication1
{
static class Program
{
/// <summary>
/// The main entry point for the application.
/// </summary>
[STAThread]
static void Main()
{
Application.EnableVisualStyles();
Application.SetCompatibleTextRenderingDefault(false);
Application.Run(new Form1());
}
}
}
form1.cs
using System;
using System.IO;
using System.Windows.Forms;
using iTextSharp.text;
using iTextSharp.text.pdf;
namespace WindowsFormsApplication1
{
public partial class Form1 : Form
{
public Form1()
{
InitializeComponent();
}
private void Form1_Load(object sender, EventArgs e)
{
//Folder that we'll work from
string workingFolder = Environment.GetFolderPath(Environment.SpecialFolder.Desktop);
string pdf1 = Path.Combine(workingFolder, "pdf1.pdf");//PDF with solid red background color
string pdf2 = Path.Combine(workingFolder, "pdf2.pdf");//PDF with text
string pdf3 = Path.Combine(workingFolder, "pdf3.pdf");//Merged PDF
//Create a basic PDF filled with red, nothing special
using (FileStream fs = new FileStream(pdf1, FileMode.Create, FileAccess.Write, FileShare.None))
{
using (Document doc = new Document(PageSize.LETTER))
{
using (PdfWriter writer = PdfWriter.GetInstance(doc, fs))
{
doc.Open();
PdfContentByte cb = writer.DirectContent;
cb.SetColorFill(BaseColor.RED);
cb.Rectangle(0, 0, doc.PageSize.Width, doc.PageSize.Height);
cb.Fill();
doc.Close();
}
}
}
//Create a basic PDF with a single line of text, nothing special
using (FileStream fs = new FileStream(pdf2, FileMode.Create, FileAccess.Write, FileShare.None))
{
using (Document doc = new Document(PageSize.LETTER))
{
using (PdfWriter writer = PdfWriter.GetInstance(doc, fs))
{
doc.Open();
doc.Add(new Paragraph("This is a test"));
doc.Close();
}
}
}
//Create a basic PDF
using (FileStream fs = new FileStream(pdf3, FileMode.Create, FileAccess.Write, FileShare.None))
{
using (Document doc = new Document(PageSize.LETTER))
{
using (PdfWriter writer = PdfWriter.GetInstance(doc, fs))
{
doc.Open();
//Get page 1 of the first file
PdfImportedPage imp1 = writer.GetImportedPage(new PdfReader(pdf1), 1);
//Get page 2 of the second file
PdfImportedPage imp2 = writer.GetImportedPage(new PdfReader(pdf2), 1);
//Add the first file to coordinates 0,0
writer.DirectContent.AddTemplate(imp1, 0, 0);
//Since we don't call NewPage the next call will operate on the same page
writer.DirectContent.AddTemplate(imp2, 0, 0);
doc.Close();
}
}
}
this.Close();
}
private void Form1_Load_1(object sender, EventArgs e)
{
}
}
}
I expect the output to be a working Pdf Merge/combine to where it has two buttons asking which file to upload for the parent pdf and then another button for child pdf and then something that shows the child pdf merged into the parent pdf.

I am trying to convert PDF bookmarks into named destinations with C# and iTextSharp 5 library. Unfortunately iTextSharp seems not to write named destinations into the target PDF file.
using System;
using System.Collections.Generic;
using iTextSharp.text.pdf;
using iTextSharp.text;
using System.IO;
namespace PDFConvert
{
class Program
{
static void Main(string[] args)
{
String InputPdf = #"test.pdf";
String OutputPdf = "out.pdf";
PdfReader reader = new PdfReader(InputPdf);
var fileStream = new FileStream(OutputPdf, FileMode.Create, FileAccess.Write, FileShare.None);
var list = SimpleBookmark.GetBookmark(reader);
PdfStamper stamper = new PdfStamper(reader, fileStream);
foreach (Dictionary<string, object> entry in list)
{
object o;
entry.TryGetValue("Title", out o);
String title = o.ToString();
entry.TryGetValue("Page", out o);
String location = o.ToString();
String[] aLoc = location.Split(' ');
int page = int.Parse(aLoc[0]);
PdfDestination dest = new PdfDestination(PdfDestination.XYZ, float.Parse(aLoc[2]), float.Parse(aLoc[3]), float.Parse(aLoc[4]));
stamper.Writer.AddNamedDestination(title, page, dest);
// stamper.Writer.AddNamedDestinations(SimpleNamedDestination.GetNamedDestination(reader, false), reader.NumberOfPages);
}
stamper.Close();
reader.Close();
}
}
}
I already tried to use PdfWriter instead of PdfStamper, with the same result. I have definitely calls of stamper.Writer.AddNamedDestination(title, page, dest); but no sign of NamedDestinations in my target file.
I have found a solution using iText 7 instead of 5. Unfortunately the syntax is completely different. In my code below I only consider the second level Bookmarks ("Outline") of my PDF.
using iText.Kernel.Pdf;
using iText.Kernel.Pdf.Navigation;
using System;
namespace PDFConvert
{
class Program
{
static void Main(string[] args)
{
String InputPdf = #"test.pdf";
String OutputPdf = "out.pdf";
PdfDocument pdfDoc = new PdfDocument(new PdfReader(InputPdf), new PdfWriter(OutputPdf));
PdfOutline outlines = pdfDoc.GetOutlines(false);
// first level
foreach (var outline in outlines.GetAllChildren())
{
// second level
foreach (var second in outline.GetAllChildren())
{
String title = second.GetTitle();
PdfDestination dest = second.GetDestination();
pdfDoc.AddNamedDestination(title, dest.GetPdfObject());
}
}
pdfDoc.Close();
}
}
}
How can i set an image to a pdf field in existing pdf file?
I'm using the iTextSharp object.
Setting the text field is working fine. No problem in it.
pdfFormFields.SetField("Firstname", "Mujeeb");
Please help.
Remove the Text field and replace it with a Pushbutton field of the same size and position. If you set the Pushbutton to READ_ONLY then it can't be pressed and it will look like a static image. This keeps the image you're trying to add as a field annotation instead of adding it to the page content.
void ConvertTextFieldToImage(string inputFile, string fieldName, string imageFile, string outputFile)
{
using (PdfStamper stamper = new PdfStamper(new PdfReader(inputFile), File.Create(outputFile)))
{
AcroFields.FieldPosition fieldPosition = stamper.AcroFields.GetFieldPositions(fieldName)[0];
PushbuttonField imageField = new PushbuttonField(stamper.Writer, fieldPosition.position, fieldName);
imageField.Layout = PushbuttonField.LAYOUT_ICON_ONLY;
imageField.Image = iTextSharp.text.Image.GetInstance(imageFile);
imageField.ScaleIcon = PushbuttonField.SCALE_ICON_ALWAYS;
imageField.ProportionalIcon = false;
imageField.Options = BaseField.READ_ONLY;
stamper.AcroFields.RemoveField(fieldName);
stamper.AddAnnotation(imageField.Field, fieldPosition.page);
stamper.Close();
}
}
To the best of my knowledge you can't technically set a standard PDF field as an image (although you might be able to do this with XFA).
The workaround, however, is to just create a standard iTextSharp image and scale it to the form field's dimensions and place it where the field is.
Below is a full working C# 2010 WinForms app targeting iTextSharp 5.1.1.0 that shows how to do this. It starts by creating a very simple PDF with a single form field on it called "firstName". The second part of the program then gets the position and dimensions of that field and places an image there scaled appropriately. See the comments in the code for further details.
using System;
using System.ComponentModel;
using System.Text;
using System.Windows.Forms;
using System.IO;
using iTextSharp.text;
using iTextSharp.text.pdf;
namespace WindowsFormsApplication1
{
public partial class Form1 : Form
{
public Form1()
{
InitializeComponent();
}
private void Form1_Load(object sender, EventArgs e)
{
string baseFile = Path.Combine(Environment.GetFolderPath(Environment.SpecialFolder.Desktop), "StartFile.pdf");
string secondFile = Path.Combine(Environment.GetFolderPath(Environment.SpecialFolder.Desktop), "SecondFile.pdf");
string TestImage = Path.Combine(Environment.GetFolderPath(Environment.SpecialFolder.Desktop), "Test.jpg");
//Create a very simple PDF with a single form field called "firstName"
using (FileStream fs = new FileStream(baseFile, FileMode.Create, FileAccess.Write, FileShare.None))
{
using (Document doc = new Document(PageSize.LETTER))
{
using (PdfWriter writer = PdfWriter.GetInstance(doc, fs))
{
doc.Open();
writer.AddAnnotation(new TextField(writer, new iTextSharp.text.Rectangle(0, 0, 100, 100), "firstName").GetTextField());
doc.Close();
}
}
}
//Create a second file "filling out" the form above
using (FileStream fs = new FileStream(secondFile, FileMode.Create, FileAccess.Write, FileShare.None))
{
using (PdfStamper stamper = new PdfStamper(new PdfReader(baseFile), fs))
{
//GetFieldPositions returns an array of field positions if you are using 5.0 or greater
//This line does a lot and should really be broken up for null-checking
iTextSharp.text.Rectangle rect = stamper.AcroFields.GetFieldPositions("firstName")[0].position;
//Create an image
iTextSharp.text.Image img = iTextSharp.text.Image.GetInstance(TestImage);
//Scale it
img.ScaleAbsolute(rect.Width, rect.Height);
//Position it
img.SetAbsolutePosition(rect.Left, rect.Bottom);
//Add it to page 1 of the document
stamper.GetOverContent(1).AddImage(img);
stamper.Close();
}
}
this.Close();
}
}
}
This is the answer that works for placing an image in a specific location. `
using (PdfStamper stamper = new PdfStamper(new PdfReader(fromFilePath), File.Create("toFilePath")))
{
AcroFields.FieldPosition fieldPosition = stamper.AcroFields.GetFieldPositions("btn1")[0];
PushbuttonField imageField = new PushbuttonField(stamper.Writer, fieldPosition.position, "btn1Replaced");
imageField.Layout = PushbuttonField.LAYOUT_ICON_ONLY;
imageField.Image = iTextSharp.text.Image.GetInstance(ImageLocationPath);
imageField.ScaleIcon = PushbuttonField.SCALE_ICON_ALWAYS;
imageField.ProportionalIcon = false;
imageField.Options = BaseField.READ_ONLY;
stamper.AcroFields.RemoveField("btn1");
stamper.AddAnnotation(imageField.Field, fieldPosition.page);
stamper.Close();
}
Hi I have a pdf I created using itextsharp.
Using pdfreader I am reading the created pdf into a pdfstamper.
Now I am trying to use the pdfstamper to add a black rectangle the size of the page on all pages. How do i do this?
Also I cannot use document to add the rectangle because the stream is close!
MemoryStream stream = new MemoryStream();
PdfReader pdfReader = new PdfReader(output.ToArray());
PdfStamper stamper = new PdfStamper(pdfReader, stream);
for (int x = 0; x < stamper.Reader.NumberOfPages; x++)
{
Rectangle rectangle = document.PageSize;
rectangle.BackgroundColor = new BaseColor(0, 0, 0);
//stamper.Writer.AcroForm.
//document.Add(rectangle);
}
output.Close();
pdfReader.Close();
stamper.Close();
If you want to draw using the PdfStamper then you need to use the PdfContentByte which you can get by calling stamper.GetOverContent(pageNum). There's a specific command on that object called Rectangle which does exactly what you want it to do. Also, remember that pages within a PDF start numbering at one and not zero.
Below is a full working C# 2010 WinForm app targeting iTextSharp 5.1.1.0 that should do what you're looking for, I think. You'll need to modify it to support the MemoryStream but that should be pretty easy.
using System;
using System.Text;
using System.Windows.Forms;
using System.IO;
using iTextSharp.text;
using iTextSharp.text.pdf;
namespace WindowsFormsApplication1
{
public partial class Form1 : Form
{
public Form1()
{
InitializeComponent();
}
private void Form1_Load(object sender, EventArgs e)
{
string inputFile = Path.Combine(Environment.GetFolderPath(Environment.SpecialFolder.Desktop), "input.pdf");
string outputFile = Path.Combine(Environment.GetFolderPath(Environment.SpecialFolder.Desktop), "output.pdf");
PdfReader pdfReader = new PdfReader(inputFile);
using (FileStream fs = new FileStream(outputFile, FileMode.Create, FileAccess.Write, FileShare.None))
{
using (PdfStamper stamper = new PdfStamper(pdfReader, fs))
{
int PageCount = pdfReader.NumberOfPages;
for (int x = 1; x <= PageCount; x++)
{
PdfContentByte cb = stamper.GetOverContent(x);
iTextSharp.text.Rectangle rectangle = pdfReader.GetPageSizeWithRotation(x);
rectangle.BackgroundColor = BaseColor.BLACK;
cb.Rectangle(rectangle);
}
}
}
this.Close();
}
}
}
I am using c#.net and need for some data to be displayed in a .pdf file. I am able to do so by using a PdfTable but then it is displayed in a tabular format.
I want a simple format like:
I dont want the exact tabular format.I am using iTextSharp dll.
Is it possible to display data in the above metioned format?
Any suggestions are welcome..
You can use PdfParagraph class to render genreal text in PDF
So when you say that you don't want exact tabular format are you talking about the borders? If so, I'd recommend using a PdfPTable and turning the borders off then. Cells in a PdfPTable are all based on the table's DefaultCell, so to turn the borders off for a table called t you'd do this:
t.DefaultCell.Border = 0;
Below is a full working WinForms app targetting iTextSharp 5.1.1.0 that does exactly that:
//PdfPTable Example
using System;
using System.ComponentModel;
using System.IO;
using System.Windows.Forms;
using iTextSharp.text;
using iTextSharp.text.pdf;
namespace WindowsFormsApplication2
{
public partial class Form1 : Form
{
public Form1()
{
InitializeComponent();
}
private void Form1_Load(object sender, EventArgs e)
{
//PDF file to output
string outputFile = Path.Combine(Environment.GetFolderPath(Environment.SpecialFolder.Desktop), "Output.pdf");
//Create a basic stream to write to
using (FileStream fs = new FileStream(outputFile, FileMode.Create, FileAccess.Write, FileShare.None))
{
//Create a new PDF document
using (Document doc = new Document())
{
//Bind a the document to the stream
using (PdfWriter w = PdfWriter.GetInstance(doc, fs))
{
//Open our PDF for writing
doc.Open();
//Insert a new page into our output PDF
doc.NewPage();
//Create a three column table
PdfPTable t = new PdfPTable(3);
//Remove the border from the table
t.DefaultCell.Border = 0;
//For the first row we some extra padding
t.DefaultCell.PaddingBottom = 10;
t.AddCell("ColumnA");
t.AddCell("ColumnB");
t.AddCell("ColumnC");
//Reset the padding for the remaining cells
t.DefaultCell.PaddingBottom = 0;
t.AddCell("Value1");
t.AddCell("Value1");
t.AddCell("Value1");
t.AddCell("Value2");
t.AddCell("Value2");
t.AddCell("Value2");
//Add the table to the document
doc.Add(t);
//Close our output PDF
doc.Close();
}
}
}
this.Close();
}
}
}
If for some reason you don't want to do this with a PdfPTable you can try hacking it together with a Paragraph but unless alignment isn't important you are going to give yourself a headache. The sample below uses paragraphs and formats each "column" within the paragraph to be 20 characters each, padding spaces as necessary. NOTE: This is 20 characters of a variable-width font so things don't actually align. If you want that, either use the PdfPTable above or you are going to have to measure strings which is not fun.
//Paragraph Example
using System;
using System.ComponentModel;
using System.IO;
using System.Windows.Forms;
using iTextSharp.text;
using iTextSharp.text.pdf;
namespace WindowsFormsApplication2
{
public partial class Form1 : Form
{
public Form1()
{
InitializeComponent();
}
private void Form1_Load(object sender, EventArgs e)
{
//PDF file to output
string outputFile = Path.Combine(Environment.GetFolderPath(Environment.SpecialFolder.Desktop), "Output.pdf");
//Create a basic stream to write to
using (FileStream fs = new FileStream(outputFile, FileMode.Create, FileAccess.Write, FileShare.None))
{
//Create a new PDF document
using (Document doc = new Document())
{
//Bind a the document to the stream
using (PdfWriter w = PdfWriter.GetInstance(doc, fs))
{
//Open our PDF for writing
doc.Open();
//Insert a new page into our output PDF
doc.NewPage();
//Right-pad each "column" for a total of 20 characters
string FormatString = "{0,-20}{1,-20}{2,-20}";
//Add the first row
doc.Add(new Paragraph(String.Format(FormatString, "ColumnA", "ColumnB", "ColumnC")));
//Add a blank line
doc.Add(new Paragraph(""));
//Add the two data rows
doc.Add(new Paragraph(String.Format(FormatString, "Value1", "Value1", "Value1")));
doc.Add(new Paragraph(String.Format(FormatString, "Value2", "Value2", "Value2")));
//Close our output PDF
doc.Close();
}
}
}
this.Close();
}
}
}
In iTextSharp dll, you just pass your data by creating table/tr/td structure in string like this :
string strData = string.Emrty;
strData = "<table border='0' cellpadding='0' cellspacing='0' width='100%'>";
strData += "<tr>";
strData += "<td>";
strData += "</td>";
strData += "</tr>";
strData += "</table>";
by creating table/tr/td structure of your data, just pass this variable data to pdf, then you will get your resulted output in pdf.
I have to get an ordered list into pdf.The data stored is in html format.When exporting to pdf using itextsharp,the ol-li tags should be replaced by an ordered list.
You'll want to use iTextSharp's iTextSharp.text.html.simpleparser.HTMLWorker.ParseToList() method. Below is a full working sample WinForms app targeting iTextSharp 5.1.1.0 that does what you're looking for. See the inline comments for what's going on.
using System;
using System.Collections.Generic;
using System.Linq;
using System.Windows.Forms;
using System.IO;
using iTextSharp.text.pdf;
using iTextSharp.text;
namespace WindowsFormsApplication1
{
public partial class Form1 : Form
{
public Form1()
{
InitializeComponent();
}
private void Form1_Load(object sender, EventArgs e)
{
//File to export to
string exportFile = Path.Combine(Environment.GetFolderPath(Environment.SpecialFolder.Desktop), "HTML.pdf");
//Create our PDF document
using (Document doc = new Document(PageSize.LETTER)){
using (FileStream fs = new FileStream(exportFile, FileMode.Create, FileAccess.Write, FileShare.Read)){
using (PdfWriter writer = PdfWriter.GetInstance(doc, fs)){
//Open the doc for writing
doc.Open();
//Insert a page
doc.NewPage();
//This is our sample HTML
String HTML = "<ol><li>Row 1</li><li>Row 2</li></ol>";
//Create a StringReader to parse our text
using (StringReader sr = new StringReader(HTML))
{
//Pass our StringReader into iTextSharp's HTML parser, get back a list of iTextSharp elements
List<IElement> ies = iTextSharp.text.html.simpleparser.HTMLWorker.ParseToList(sr, null);
//Loop through each element and add to the document
foreach (IElement ie in ies)
{
doc.Add(ie);
}
}
//Close our document
doc.Close();
}
}
}
}
}
}
