Hello Sudheer,

Thanks for considering Aspose.

Let me share some details regarding HTML2PDF conversion. This is Beta version of Html2Pdf. Only simple HTML is supported. Please make sure the input HTML file is in correct format.

Can you please share the resource documents and the code snippet that you are using for conversion, so that we can test the issue at our end. We apologize for your inconvenience.

We are trying to extract an MOSS page (contains some status reports) into PDF format. The web page contains images as well. Please let me know will the dll suppport for images or not.

Please find the code snippet below:

string surl = Context.Request.Url.ToString();

Aspose.Pdf.Pdf pf = new Aspose.Pdf.Pdf();

WebClient webClient = new WebClient();

webClient.Credentials = new NetworkCredential("@UserName", "@Password");

byte[] myDataBuffer = webClient.DownloadData(surl );

MemoryStream postStream = new MemoryStream (myDataBuffer);

pf.BindHTML(postStream);

pf.Save(@"E:/PDFExt.pdf");

Hello Sudheer,

In order for us to test the issue, can you please save the MemoryStream into File object and share it so that we can test the conversion at our end.

The easiest way would be to open a file stream and then use:

byte[] data = stream.ToArray();
FileStream fs = new FileStream(newFile, FileMode.CreateNew);
fs.Write(data, 0, data.Length);

That’s relatively inefficient though, as it involves copying the buffer. It’s fine for small streams, but for huge amounts of data you should consider using:

fileStream.Write(memoryStream.GetBuffer(), 0, memoryStream.Position);

(assuming the memory stream is already positioned at the end).

According to your scenario you can use myDataBuffer- instead of data array used in above example. And regarding your query to add Images during PDF conversion, please visit the following link for HTML to PDF using MemoryStream.
