Multi-page TIFF images to PDF problem

I have a new problem. I am converting multi-page TIFF images to PDFs. The first page comes out really tiny, but the rest of the pages are fine. I’ve tried several TIFF images and get the same results. Hoping you can tell me what I need to do to get the size correct on the first page.
Here’s the conversion code I’m using:

Blockquote
public Document ConvertTiffToPdf(byte[] byteStream, string url)
{
//Instantiate a Pdf object by calling its empty constructor
Document pdf1 = new Document();

        // Add a page to pages collection of document
        Page page = pdf1.Pages.Add();
        

        MemoryStream mystream = new MemoryStream(byteStream);
        // Instantiate BitMap object with loaded image stream
        Bitmap b = new Bitmap(mystream);

        // Set margins so image will fit, etc.
        page.PageInfo.Margin.Bottom = 0;
        page.PageInfo.Margin.Top = 0;
        page.PageInfo.Margin.Left = 0;
        page.PageInfo.Margin.Right = 0;

        page.CropBox = new Aspose.Pdf.Rectangle(0, 0, b.Width, b.Height);

        // Create an image object
        Aspose.Pdf.Image image1 = new Aspose.Pdf.Image();

        //Set the type of image using ImageFileType enumeration
        //image1.FileType = ImageFileType.;
        // Add the image into paragraphs collection of the section
        page.Paragraphs.Add(image1);
        // Set the image file stream
        image1.ImageStream = mystream;

        if (url != null && url.Contains("/"))
        {
            var strings = url.Split('/');
            var baseFileName = strings[strings.Length - 1].Split('.')[0];
            string fileName = String.Format("c:\\temp\\{0}.pdf", baseFileName);
            //Save the Pdf
            pdf1.Save(fileName);
        }
        // Close the MemoryStream Object
        //ms.Close();
        return pdf1;
    }

Thank you for contacting support.

Would you please share source and generated ZIP files so that we may try to reproduce and investigate it in our environment.

I have replied to the support email with a zip file of the code for the Windows Service. It does pull the document from a SharePoint repository using a web service. Thus I work from the bytes in the response of the service.

Please note that forum attachments are accessible to thread owner and Aspose staff only so kindly share requested data here instead of replying via email.

I am attaching the code here now.
Note that it uses a service to grab the tiff file, but you will most certainly be able to see the code that converts the tiff to a pdf and the code that prints.
