Generate PDF from HTML

http://sourceforge.net/projects/pdfizer

First, set a reference in your project to the 3 DLL's that Pdfizer uses. Here are the 3 dll names to set a reference to:

ICSharpCode.SharpZipLib.dll (This component is used to parse the HTML)

itextsharp.dll (This component is used by Pdfizer to create the PDF document)

Pdfizer.dll (This is the main component with the HtmlToPdf object that executes the conversion operations).

Now we can add some code to use this component. Here is the code to generate a PDF from some HTML specified:

// set a path to where you want to write the PDF to.

string sPathToWritePdfTo = @"C:/new_pdf_name.pdf";

// build some HTML text to write as a PDF.  You could also

// read this HTML from a file or other means.

// NOTE: This component doesn't understand CSS or other

// newer style HTML so you will need to use depricated

// HTML formatting such as the <font> tag to make it look correct.

System.Text.StringBuilder sbHtml = new System.Text.StringBuilder();

sbHtml.Append("<html>");

sbHtml.Append("<body>");

sbHtml.Append("<font size='14'>My Document Title Line</font>");

sbHtml.Append("<br />");

sbHtml.Append("This is my document text");

sbHtml.Append("</body>");

sbHtml.Append("</html>");

// create file stream to PDF file to write to

using (System.IO.Stream stream = new System.IO.FileStream(sPathToWritePdfTo, System.IO.FileMode.OpenOrCreate))

    // create new instance of Pdfizer

    Pdfizer.HtmlToPdfConverter htmlToPdf = new Pdfizer.HtmlToPdfConverter();

    // open stream to write Pdf to to

    htmlToPdf.Open(stream);

    // write the HTML to the component

    htmlToPdf.Run(sbHtml.ToString());

    // close the write operation and complete the PDF file

    htmlToPdf.Close();

This component also supports PDF Chapters. You could add a single line of code right before the Run() method to make the HTML specified a single chapter like this:

// open stream to write Pdf to to

htmlToPdf.Open(stream);

// add a chapter for this HTML

htmlToPdf.AddChapter("My Chapter Title 1");

// write the HTML to the component

htmlToPdf.Run(sbHtml.ToString());

Repeat the AddChapter() and Run() methods for each chapter you want to add and then Close() to commit it to the PDF.
