How to display TIFF (in form of Byte[]) on Silverlight Image control

I created a window service to put all of my TIFF files into database and stored them as Byte[].

Now I want to be able to display them through Silverlight Image control

So i use the Converter during binding XAML in order to convert the Byte[] to Bitmap because the Image.Source only accept eitheir URI (I don't have the file stored on server so can't use this method) or Bitmap.

BitmapImage bmi = new BitmapImage();
if (value != null)
{
    ImageGallery imageGallery = value as ImageGallery;
    byte[] imageContent = imageGallery.ImageContent;
    string imageType = imageGallery.ImageType;
    using (MemoryStream ms = new MemoryStream(imageContent))
    {
        bmi.SetSource(ms);
    }
}
return bmi;

However, I get the exception at bmi.SetSource(ms) because Silverlight only supports JPEG and PNG images.

So I did more research and knew that i should convert the bytes of TIFF to bytes of JPEG or PNG then it will work.

To do that I tried two methods:

• Doing the conversion on server: in my RIA service call, after retrieving the ImageGallery, I loop through the available image to convert the bytes of TIFF to the bytes of JPEG.

BUT IT DOESN'T WORK.... Can you tell me where I did wrong?

public IQueryable GetImageGalleries()
{
    var imageGalleries = this.ObjectContext.ImageGalleries.OrderBy(i=>i.ImageName);
    foreach (ImageGallery imageGallery in imageGalleries)
    {
        if (imageGallery.ImageType == ".tif" || imageGallery.ImageType == ".tiff")
        {
            //Convert the Tiff byte array format into JPEG stream format
            System.Drawing.Bitmap dImg = new System.Drawing.Bitmap(new MemoryStream(imageGallery.ImageContent));
            MemoryStream ms = new MemoryStream();
            dImg.Save(ms, System.Drawing.Imaging.ImageFormat.Jpeg);

            //then convert the JPEG stream format into JPEG byte array format
            byte[] buf = new byte[ms.Length];  
            ms.Read(buf, 0, buf.Length);

            //Changing the format tiff byte[] of ImageGallery to jpeg byte[] 
            imageGallery.ImageContent = buf;
        }
    }
    return imageGalleries;
}

• The other solution is to use LibTiff.Net library to convert directly the Byte[] of TIFF to WritableBitmap directly on Silverlight.

However, after digging through their sample application or using Reflector to see the source code functions, I still can't figure out how to use their library to convert the bytes of TIFF to WritableBitmap JPEG (or PNG) because their sample only show the API for using the search the TIFF in a file directory. In my case, I don't have an existing file on server.

Can someone help me how to show the TIFF file on Image control of Silverlight?

I searched the forum but didn't find any solid answer for this.

thanks
