HTML to PDF conversion using Aspose

I am new to Aspose but I have successfully converted several file formats into PDF's but I am struck with HTML to PDF conversion. I am able to convert a HTML file into a PDF successfully but the CSS part is not rendering into the generated PDF. Any idea on this? I saved www.google.com as my input HTML file. Here is my controller code.

using Aspose.Pdf.Generator


Pdf pdf = new Pdf();
pdf.HtmlInfo.CharSet = "UTF-8";
Section section = pdf.Sections.Add();
StreamReader r = File.OpenText(@"Local HTML File Path");
Text text2 = new Aspose.Pdf.Generator.Text(section, r.ReadToEnd());
pdf.HtmlInfo.ExternalResourcesBasePath = "Local HTML File Path";
text2.IsHtmlTagSupported = true;
text2.IsFitToPage = true;
section.Paragraphs.Add(text2);
pdf.Save(@"Generated PDF File Path");

Am i missing something? Any kind of help is greatly appreciated.

Thanks

Try this.. This is working nice for me

var license = new Aspose.Pdf.License();
license.SetLicense("Aspose.Pdf.lic");

var license = new Aspose.Html.License();
license.SetLicense("Aspose.Html.lic");

using (MemoryStream memoryStream = new MemoryStream())
{
      var options = new PdfRenderingOptions();
      using (PdfDevice pdfDevice = new PdfDevice(options, memoryStream))
      {
          using (var renderer = new HtmlRenderer())
          {
              using (HTMLDocument htmlDocument = new HTMLDocument(content, ""))
              {
                   renderer.Render(pdfDevice, htmlDocument);
                   //Save memoryStream into output pdf file
              }
           }
       }
 }

content is string type which is my html content.

My name is Tilal Ahmad and I am developer evangelist at Aspose.

Please use new DOM approach(Aspose.Pdf.Document) for HTML to PDF conversion. In this approach to render external resources(CSS/Images/Fonts) you need to pass resources path to HtmlLoadOptions() method. Please check following documentation links for the purpose.

Convert HTML to PDF (new DOM)

HtmlLoadOptions options = new HtmlLoadOptions(resourcesPath);
Document pdfDocument = new Document(inputPath, options);
pdfDocument.Save("outputPath");

Convert Webpage to PDF(new DOM)

// Create a request for the URL.
WebRequest request = WebRequest.Create("https:// En.wikipedia.org/wiki/Main_Page");
// If required by the server, set the credentials.
request.Credentials = CredentialCache.DefaultCredentials;
// Time out in miliseconds before the request times out
// Request.Timeout = 100;

// Get the response.
HttpWebResponse response = (HttpWebResponse)request.GetResponse();

// Get the stream containing content returned by the server.
Stream dataStream = response.GetResponseStream();
// Open the stream using a StreamReader for easy access.
StreamReader reader = new StreamReader(dataStream);
// Read the content.
string responseFromServer = reader.ReadToEnd();
reader.Close();
dataStream.Close();
response.Close();

MemoryStream stream = new MemoryStream(System.Text.Encoding.UTF8.GetBytes(responseFromServer));
HtmlLoadOptions options = new HtmlLoadOptions("https:// En.wikipedia.org/wiki/");


// Load HTML file
Document pdfDocument = new Document(stream, options);

options.PageInfo.IsLandscape = true;
// Save output as PDF format
pdfDocument.Save(outputPath);

Try using media attribute in each style tag

<style media="print">

and then provide the html file to your Aspose.Pdf Generator.
