I'm not sure what the question is. Is it about tiff or about using ASP.NET?

Subject: [iText-questions] tiff to pdf converter help need soon
Hi all,
I am trying to use the iTextSharp dll to convert a tiff image that is in
binary format in memory to a pdf and then display it in a web page using a c#
web page. I don’t want to save any files to the hard drive; I want to keep
everything in memory. I am having trouble with the line of code
“System.Drawing.Bitmap bm = new
System.Drawing.Bitmap((Stream)((byte[])command.Parameters[8].Value));”, not
sure what to do at this point. Hoping to use the
“Response.BinaryWrite(ByteArray);” command to display on a web page. See code
below.
Thanks
// creation of the document with a certain size and certain margins
iTextSharp.text.Document document = new
iTextSharp.text.Document(iTextSharp.text.PageSize.A4, 0, 0, 0, 0);
// creation of the different writers
iTextSharp.text.pdf.PdfWriter writer =
iTextSharp.text.pdf.PdfWriter.GetInstance(document, new
System.IO.FileStream(Server.MapPath("~result.pdf"), System.IO.FileMode.Create));
// load the tiff image and count the total pages
//System.Drawing.Bitmap bm = new
System.Drawing.Bitmap(Server.MapPath("~/App_Data/source.tif"));
System.Drawing.Bitmap bm = new
System.Drawing.Bitmap((Stream)((byte[])command.Parameters[8].Value));
int total =
bm.GetFrameCount(System.Drawing.Imaging.FrameDimension.Page);
document.Open();
iTextSharp.text.pdf.PdfContentByte cb = writer.DirectContent;
for (int k = 0; k < total; ++k)
{
bm.SelectActiveFrame(System.Drawing.Imaging.FrameDimension.Page,
k);
iTextSharp.text.Image img = iTextSharp.text.Image.GetInstance(bm,
System.Drawing.Imaging.ImageFormat.Bmp);
// scale the image to fit in the page
img.ScalePercent(72f / img.DpiX * 100);
img.SetAbsolutePosition(0, 0);
cb.AddImage(img);
document.NewPage();
}
document.Close();
