Does the library PDFSharp can - like iTextSharp - generate PDF files *take into account HTML formatting *? (bold (strong), spacing

    Have you guys heard of this. I might be answering very late but I thought it helps. It is very simple and works well.

    var htmlContent = String.Format("<body>Hello world: {0}</body>", 
        DateTime.Now);
var htmlToPdf = new NReco.PdfGenerator.HtmlToPdfConverter();
var pdfBytes = htmlToPdf.GeneratePdf(htmlContent);

    Edit: I came here with the question of converting HTML code to PDF using 'PDFSharp' and found out that 'PDFSharp' cannot do it then I found out about NReco and it worked for me so I felt it might help someone just like me.

    HTML Renderer for PDF using PdfSharp can generate a PDF from an HTML

    1. as an image, or
    2. as text

    before inserting to the PDF.

    To render as an image, please refer to the code from Diego answer.

    To render as text, please refer code below:

    static void Main(string[] args)
{
    string html = File.ReadAllText(@"C:\Temp\Test.html");
    PdfDocument pdf = PdfGenerator.GeneratePdf(html, PageSize.A4, 20, null, OnStylesheetLoad, OnImageLoadPdfSharp);
    pdf.Save(@"C:\Temp\Test.pdf");
}

public static void OnImageLoadPdfSharp(object sender, HtmlImageLoadEventArgs e)
{
    var imgObj = Image.FromFile(@"C:\Temp\Test.png");
    e.Callback(XImage.FromGdiPlusImage(imgObj));    
}

public static void OnStylesheetLoad(object sender, HtmlStylesheetLoadEventArgs e)
{
    e.SetStyleSheet = @"h1, h2, h3 { color: navy; font-weight:normal; }";
}

    HTML code

    <html>
    <head>
        <title></title>
        <link rel="Stylesheet" href="StyleSheet" />      
    </head>
    <body>
        <h1>Images
            <img src="ImageIcon" />
        </h1>
    </body>
</html>

    No, PDFsharp does not currently include code to parse HTML files.
