I'm using the HTMLFormatProvider to import HTML content into a RadFlowDocument. This content contains inline <svg> XML. When I use a PdfFormatProvider to attempt to export the HTML page as a PDF, the image is blank. Is it possible to export the SVG as part of that PDF when it is not a file but the actual SVG xml in the page?

 


                string htmlContent = task.Result;

                HtmlFormatProvider htmlProvider = new HtmlFormatProvider();
                
                RadFlowDocument document = htmlProvider.Import(htmlContent);
               
                PdfFormatProvider pdfProvider = new PdfFormatProvider();

                Telerik.Windows.Documents.Extensibility.JpegImageConverterBase jpegImageConverter = new JpegImageConverter();
                Telerik.Windows.Documents.Extensibility.FixedExtensibilityManager.JpegImageConverter = jpegImageConverter;
                
                foreach(Section section in document.Sections)
                {
                    section.Rotate(Telerik.Windows.Documents.Model.PageOrientation.Landscape);
                    section.PageMargins = new Telerik.Windows.Documents.Primitives.Padding(10);
                }
                byte[] pdfBytes = pdfProvider.Export(document);

Hello Bill,

The HtmlFormatProvider does not support the SVG tag, which is why the image is not imported/exported. We have a feature request for this on our feedback portal. You can track its progress, subscribe to status changes, and add your comment to it here: WordsProcessing: Add support for the SVG element in HtmlFormatProvider.

I am afraid I cannot suggest an alternative solution for this.

I want to apologize for the inconvenience this missing functionality is causing you.

Regards,
