I want to convert HTML into PDF in windows form. I have come across many fabulous articles online such as these:
http://www.aspsnippets.com/Categories/iTextSharp.aspx
http://www.aspsnippets.com/Articles/Export-HTML-DIV-contents-to-PDF-using-iTextSharp-in-ASPNet.aspx
http://www.aspsnippets.com/Articles/Export-ASP.Net-GridView-to-PDF-with-Custom-Columns-Widths-using-iTextSharp.aspx
But they do not quite address my problem.
Is it possible that I can just pass a string of HTML and convert it into PDF in Winform?
For example :
string html = "<table><tr><td>Arbaaz</td><tr></table>"
Can I just pass this string to some iText method to create PDF?
Got the answer I was looking for here ..
Document document = new Document();
PdfWriter.GetInstance(document, new FileStream(Request.PhysicalApplicationPath + "\\MySamplePDF.pdf", FileMode.Create));
document.Open();
iTextSharp.text.html.simpleparser.HTMLWorker hw =
new iTextSharp.text.html.simpleparser.HTMLWorker(document);
hw.Parse(new StringReader(htmlText));
document.Close();

I'm using the iTextSharp library to convert my html to pdf. The issue is I'm trying to add checkbox appearance using the below code:
string HTML,public static String FONT = "c:/windows/fonts/WINGDING.TTF";
public static String TEXT = "o";
public void HTMLToPdf( string FileName)
{
string HTML="<!DOCTYPE html>
<html>
<head><title></title><meta charset='UTF-8'></head>
<body><div class='mystyle'>Here i want to print many checkbox lik appearances</div></body>
<html>";
Document pdfDoc = new Document(PageSize.A4, 30f, 30f, 10f, 10f);
pdfDoc.Add(p);
BaseFont bf = BaseFont.CreateFont(FONT, BaseFont.IDENTITY_H, BaseFont.EMBEDDED);
Font f = new Font(bf, 12);
Paragraph p = new Paragraph(TEXT, f);
pdfDoc.Add(p);
}
The problem is this method adds the checkbox at the begining of pdf, please help me to attach the paragraph containing the checkbox value to my html.
Simply put, I'm getting the value at pdfDoc.Add(p), but I want it in a variable to print it many times in html.
In fact, it is not very clear what was meant in the question:
please help me to attach the paragraph containing the checkbox value to my html
I can assume that you wanted to convert HTML to PDF, and add paragraphs on the next line.
In general, it's a bad idea to use iTextSharp for this, since this library is outdated and no longer supported. I can suggest my own way of solving your problem in pdfHTML, this is an iText7 add-on. My code is in Java, but it's not much different from sharp.The main idea is not to close the document after html conversion. Because if you try to write a paragraph in a closed document, it will be at the very beginning, as in your example.
String FONT = "c:/windows/fonts/WINGDING.TTF";
String TEXT = "o";
File htmlSource = new File("checkBoxHtml.html");
File pdfDest = new File("output.pdf");
ConverterProperties converterProperties = new ConverterProperties();
Document document = HtmlConverter.convertToDocument(new FileInputStream(htmlSource),
new PdfDocument(new PdfWriter(pdfDest)), converterProperties);
PdfFont font = PdfFontFactory.createFont(FONT);
Text text = new Text(TEXT);
text.setFont(font);
Paragraph paragraph = new Paragraph();
// Adding text to the paragraph
paragraph.add(text);
// Adding paragraph to the document
document.add(paragraph);
document.close();
I am using ITextSharp to convert HTML to PDF but i want the PDF to be generated of size 5cm width. I used the following code
var pgSize = new iTextSharp.text.Rectangle(2.05f, 2.05f);
Document doc = new Document(pgSize);
but it is just resizing the pdf and my data disappeared in the pdf or get hide.
How can i align the data in the center in PDF or resize the pdf? Here is my code
public void ConvertHTMLToPDF(string HTMLCode)
{
try
{
System.IO.StringWriter stringWrite = new StringWriter();
System.Web.UI.HtmlTextWriter htmlWrite = new HtmlTextWriter(stringWrite);
StringReader reader = new StringReader(HTMLCode);
var pgSize = new iTextSharp.text.Rectangle(2.05f, 2.05f);
Document doc = new Document(pgSize);
HTMLWorker parser = new HTMLWorker(doc);
PdfWriter.GetInstance(doc, new FileStream(Server.MapPath("~") + "/App_Data/HTMLToPDF.pdf",
FileMode.Create));
doc.Open();
foreach (IElement element in HTMLWorker.ParseToList(
new StringReader(HTMLCode), null))
{
doc.Add(element);
}
doc.Close();
Response.End();
}
catch (Exception ex)
{
}
}
You are creating a PDF that measures 0.0723 cm by 0.0723 cm. That is much too small to add any content. If you want to create a PDF of 5 cm by 5 cm, you need to create your document like this:
var pgSize = new iTextSharp.text.Rectangle(141.732f, 141.732f);
Document doc = new Document(pgSize);
As for the alignment, that should be defined in the HTML, but you are using an old version of iText and you are using the deprecated HTMLWorker.
You should upgrade to iText 7 and pdfHTML as described here: Converting HTML to PDF using iText
Also: the size of the page can be defined in the #page-rule of the CSS. See Huge white space after header in PDF using Flying Saucer
Why would you make it difficult for yourself by using an old iText version, when the new version allows you to do this:
#page {
size: 5cm 5cm;
}
In vb.net I need to print the contents showing in a browser control to printer.
I have used Gecko web-browser control in winform application and there is no direct way to print the page's contents.
Either way to print direct using InnerHtml or converting that html to pdf and then printing the pdf document.
currently I am using a third party library `ItextSharpe' but it gives errors.
public byte[] GetPDF(string pHTML) {
byte[] bPDF = null;
MemoryStream ms = new MemoryStream();
TextReader txtReader = new StringReader(pHTML);
// 1: create object of a itextsharp document class
Document doc = new Document(PageSize.A4, 25, 25, 25, 25);
// 2: we create a itextsharp pdfwriter that listens to the document and directs a XML-stream to a file
PdfWriter oPdfWriter = PdfWriter.GetInstance(doc, ms);
// 3: we create a worker parse the document
HTMLWorker htmlWorker = new HTMLWorker(doc);
// 4: we open document and start the worker on the document
doc.Open();
htmlWorker.StartDocument();
// 5: parse the html into the document
htmlWorker.Parse(txtReader);
// 6: close the document and the worker
htmlWorker.EndDocument();
htmlWorker.Close();
doc.Close();
bPDF = ms.ToArray();
return bPDF;
}
Byte[] bytes;
bytes = GetPDF(browse.Document.Body.InnerHtml);
var testFile = Path.Combine(Environment.GetFolderPath(Environment.SpecialFolder.Desktop), "test.pdf");
System.IO.File.WriteAllBytes(testFile, bytes);
but throws errors while parsing.
Unable to cast object of type 'iTextSharp.text.html.simpleparser.CellWrapper' to type 'iTextSharp.text.Paragraph'.
I have seen different examples over web but this is totally different, the examples or duplicate answer is about to export panels or grids but this is dynamic HTML and i need to convert it to PDF or print directly the client area.
I was wondering if it is possible to integrate a Quicktime movie into a PDF with iTextSharp or other PDF tools. I have been able integrate images without a problem. Thanks.
Is it this you are looking for?
Edit
In short
First you have to create a movie annotation by using the CreateScreen method of the PdfAnnotation class
You can create an movie annotation using this media types .aiff, .au, .avi, .mid, .mov, .mp4, .mp4, .mpeg, .smil, .swf
Then you need to add the movie annotation to the PDF by using the AddAnnotation method of the PdfWriter
/create a document object
var doc = new Document();
//output file path
String outfile = "d:/pdfdoc.pdf";
//get PdfWriter object
PdfWriter writer=PdfWriter.GetInstance(doc, new FileStream(outfile, FileMode.Create));
//open the document for writing
doc.Open();
//Create an instance of PdfFileSpecification
PdfFileSpecification fs = PdfFileSpecification.FileEmbedded(writer, "d:/bailey.mpg", "bailey.mpg", null);
//create and add a movie annotation to PDF document
writer.AddAnnotation(PdfAnnotation.CreateScreen(writer, new Rectangle(200f, 700f, 400f, 800f), "Bailey", fs,"video/mpeg", true));
//close the document
doc.Close();
//view the result pdf file
System.Diagnostics.Process.Start(outfile);

I am trying to convert a comma separated string(CSV) file to pdf file in C# using the iTextSharp library. I would like to know if there is any other free or more efficient tool/way for this type of conversion.
You can use iTextSharp
Here's an example:
Document pdfDoc = new Document();
string path = #"c:\file.pdf";
PdfWriter writer = PdfWriter.GetInstance( pdfDoc, new FileStream(path, FileMode.OpenOrCreate));
pdfDoc.Open();
pdfDoc.Add(new Paragraph("your data"));
pdfDoc.Close();
