Convert HTML or PDF to RTF/DOC or HTML/PDF to image using DevExpress or Infragistics

Question

Hello all!

There is a way do convert HTML or PDF to RTF/DOC or HTML/PDF to image using DevExpress or Infragistics?

I tried this using DevExpress:

string html = new StreamReader(Server.MapPath(@".\teste.htm")).ReadToEnd();

            RichEditControl richEditControl = new RichEditControl();
            string rtf;
            try
            {
                richEditControl.HtmlText = html;
                rtf = richEditControl.RtfText;
            }
            finally
            {
                richEditControl.Dispose();
            }

            StreamWriter sw = new StreamWriter(@"D:\teste.rtf");
            sw.Write(rtf);
            sw.Close();

But I have a complex html content (tables, backgrounds, css etc) and the final result is not good...

I suggest you to use latest DevExpress version (version 10.1.5 this time). It handles tables much better than previous ones.

Please use the following code to avoid encoding issues (StreamReader and StreamWriter in your sample always use Encoding.UTF8 encoding, this will corrupt any content stored with another encoding):

    using (RichEditControl richEditControl = new RichEditControl()) {
        richEditControl.LoadDocument(Server.MapPath(@".\teste.htm"), DocumentFormat.Html);
        richEditControl.SaveDocument(@"D:\teste.rtf", DocumentFormat.Rtf);
    }

Also take a look at the richEditControl.Options.Import.Html and richEditControl.Options.Export.Rtf properties, you may find them useful for some cases.

To convert Html content into image or Pdf you may use the following code:

using (RichEditControl richEditControl = new RichEditControl()) {
    richEditControl.LoadDocument(Server.MapPath(@".\teste.htm"), DocumentFormat.Html);
    using (PrintingSystem ps = new PrintingSystem()) {
        PrintableComponentLink pcl = new PrintableComponentLink(ps);
        pcl.Component = richEditControl;
        pcl.CreateDocument();
        //pcl.PrintingSystem.ExportToPdf("teste.pdf");
        pcl.PrintingSystem.ExportToImage("teste.jpg", System.Drawing.Imaging.ImageFormat.Jpeg);
    }
}
