wkhtmltopdf - convert html code to pdf directly in C#

I just started a new project to provide a C# P/Invoke wrapper around wkhtmltopdf.

You can checkout my code at: https://github.com/pruiz/WkHtmlToXSharp

Greets.

Take a look at Pechkin

.NET Wrapper for WkHtmlToPdf DLL, library that uses Webkit engine to convert HTML pages to PDF.

Nuget packages:

Pechkin.Synchronized

Pechkin

Example code:

private void ConvertToPdf()
{
    var loadPath = Server.MapPath("~/HtmlTemplates");
    var loadFile = Path.Combine(loadPath, "Test.html");
    var savePath = Server.MapPath("~/Pdf");
    var saveFile = Path.Combine(savePath, DateTime.Now.ToString("HH-mm-ss.fff") + ".pdf");

    var globalConfig = new GlobalConfig()
        .SetMargins(0, 0, 0, 0)
        .SetPaperSize(PaperKind.A4);

    var pdfWriter = new SynchronizedPechkin(globalConfig);

    pdfWriter.Error += OnError;
    pdfWriter.Warning += OnWarning;

    var objectConfig = new ObjectConfig()
        .SetPrintBackground(true)
        .SetIntelligentShrinking(false);

    var pdfBuffer = pdfWriter.Convert(objectConfig, File.ReadAllText(loadFile));

    File.WriteAllBytes(saveFile, pdfBuffer);
}

private void OnWarning(SimplePechkin converter, string warningtext)
{
    throw new NotImplementedException();
}

private void OnError(SimplePechkin converter, string errortext)
{
    throw new NotImplementedException();
}

wkhtmltopdf is a free tool, but it's not written in .NET and it could be kind of hard to integrate into your asp.net application.

you can take a look at iTextSharp, which is free, but cannot handle any kind of html, or you can take a look at commercial tools to convert html to pdf, like ExpertPDF or ABCpdf, that can handle any html/css.
