ITextSharp adding direct content bar code change font color for paragraphs

I'm creating an application in c# for generation of some pdf files with bar code in it.
I'm using the memory stream and placing data to the table (one column) which I'll write to the pdf file at the end.
Everything is working fine till I need to add bar code. For that I use direct content.
pdfWriter = PdfWriter.GetInstance(pdfToCreate, outputStream);
PdfContentByte cb = new PdfContentByte(pdfWriter);
iTextSharp.text.Image bc128 = code128.CreateImageWithBarcode(cb, null, null);
After I create bar code I add it to the table using:
tableout.AddCell(image128);
And then I have a problem. Rows from the table that I've created before are shown, but I don't see a text. If I comment line with bar code addition everything is OK.
I've found one comment on forum:
Yep. Foreground text color is defined by the Font for the high-level
text layout code. When you start using a PdfContentByte directly, the
font and color become separated, but not until then.
How can I solve this?
I know that I can use system drawning method but image with bar code is not so clear.

PdfContentByte is for direct rendering to absolute positions in the pdf. But what you need is an IElement you can add to the "document stack".
Try this (using full namespaces just to clearly identify the classes):
Barcode128 barcode = new Barcode128();
System.Drawing.Image img = barcode.CreateDrawingImage(System.Drawing.Color.Black, System.Drawing.Color.White);
iTextSharp.text.Image itextImg = iTextSharp.text.Image.GetInstance(img, System.Drawing.Imaging.ImageFormat.Bmp);
table.AddCell(new PdfPCell(itextImg));

I know that I can use system drawning method but image with bar code is not so clear.
Here is a code that I use. I'm trying to get documents whit different sizes depending on the number of lines in the document. So I'm using memory stream (not shown here). My idea is to write data to the table in memory and count lines. After that I will create new pdf document and add table to that document.
If I comment a line:
table.AddCell(image128);
both documents are the same. But if I leave that line in code final document shows all rows but text in rows is not visible. If I open second docu,ent in firefox I can even see a bar codes.
Any suggestion will be great. Or is there a different way to get documents with different sizes depending on amount of content.

Adding text to a PDF file from a text file [duplicate]

This question already has answers here:
Convert TXT file to PDF using iText (keep formatting)
(3 answers)
Closed 6 years ago.
This is my code:
using (FileStream msReport = new FileStream(pdfPath, FileMode.Create))
{
//step 1
using (Document pdfDoc = new Document(PageSize.A4, 10f, 10f, 140f, 10f))
{
try
{
// step 2.
StreamReader sr = new StreamReader("TextFile.txt");
string line;
PdfWriter pdfWriter = PdfWriter.GetInstance(pdfDoc, msReport);
pdfWriter.PageEvent = new ITextEvents();
//open the stream
pdfDoc.Open();
for (int i = 0; i < 100; i++)
{
if ((line = sr.ReadLine()) != null)
{
Paragraph para = new Paragraph(line, new iTextSharp.text.Font(iTextSharp.text.Font.FontFamily.HELVETICA, 6));
para.Alignment = Element.ALIGN_LEFT;
pdfDoc.Add(para);
//pdfDoc.NewPage();
}
}
sr.Close();
pdfDoc.Close();
and it's working...It reads the text file that is in my computer and adds it to PDF... The problem is - it doesn't keep the formatting from the text file. It just adds text. And I need to keep it the way it is. Is there any way to keep the formatting of the text? Can I somehow add it to a table and format the table, or something like that?

Try this one
using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Threading.Tasks;
using System.IO;
using iTextSharp;
using iTextSharp.text;
using iTextSharp.text.pdf;
namespace TxtToPdf
{
class Program
{
static void Main(string[] args)
{
//Read the Data from Input File
StreamReader rdr = new StreamReader("Path/Test.txt");
//Create a New instance on Document Class
Document doc = new Document();
//Create a New instance of PDFWriter Class for Output File
PdfWriter.GetInstance(doc, new FileStream("Path/Test.pdf", FileMode.Create));
//Open the Document
doc.Open();
//Add the content of Text File to PDF File
doc.Add(new Paragraph(rdr.ReadToEnd()));
//Close the Document
doc.Close();
//Open the Converted PDF File
System.Diagnostics.Process.Start("Path/Test.pdf");
}
}
}

You can do it by reading escape sequence too like when line changes you should Read it as \n and then write it in PDF with your text.

EMGU CV (OpenCV for .Net) "Corrupts" image where itextsharp won't write all of it to a pdf

I have a simple block of code to create a pdf from an image using itextsharp. It works fine on it's own. However I wanted to convert the image to gray scale before copying it to the pdf. Since I'm already familiar with EMGU, I used that to convert the image. However, the instant EMGU touches the bitmap, itext sharp will only render a corner of the image rather than the whole thing (I've confirmed both in the debugger and by saving the new image back out that it is complete):
No EMGU:
Bitmap loaded to an EMGU Image:
Below is the code, with the 3 EMGU lines commented out (compiles to "good"):

How can i set an image to a pdf field in existing pdf file?

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();
}

Using PdfStamper to add a rectangle

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.

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();
