We have implemented a new option that allows you to flatten form fields in a PDF document. An example of its usage is shown in the following code snippet.

Please use this code example with the next version of Aspose.HTML for .NET 22.12. We will inform you once new version of Aspose.HTML is available.

string customizedHTML = File.ReadAllText(@"C:\temp\form.html");
MemoryStream outStream = new MemoryStream();

// Save the document to stream.
using (var document = new Aspose.Html.HTMLDocument(customizedHTML.ToString(), @"C:\inetpub\wwwroot\cDevWorkflow\"))
{
    // Create the PDF Device and specify the output file to render
    using (var device = new Aspose.Html.Rendering.Pdf.PdfDevice(outStream))
    {
        device.Options.PageSetup.AnyPage.Margin = new Aspose.Html.Drawing.Margin(0, 0, 0, 0);
        device.Options.PageSetup.AdjustToWidestPage = true;
        device.Options.Css.MediaType = MediaType.Screen;
        // Flatten all form fields
        device.Options.FormFieldBehaviour = FormFieldBehaviour.Flattened;

        // Render HTML to PDF
        document.RenderTo(device);

        byte[] pdfBytes = outStream.ToArray();
        string filePath = @"C:\temp\output.pdf";

        using (FileStream oSourceStream = File.Create(filePath))
        {
            oSourceStream.Seek(0, SeekOrigin.End);
            oSourceStream.Write(pdfBytes, 0, pdfBytes.Length);
        }
    }
}
