Ok Thank you for ur reply.Actually rawdata is a byte array which contains the bytes in array format coming from database.I am getting the rawdata array filled with numbers on each index of array.
I guess the problem is i am converting path to byte array and saving in database..If that i am doing..then how can i extract image from image path as wpf has no file upload control?

From the open file dialog box image is selected and that path is kept in txtBrowseFile.Text further from text box it is used in :
private void fillbitmap()
{
#region load image with StreamSrouce
bitmapImage = new BitmapImage();
bitmapImage.BeginInit();
bitmapImage.StreamSource = System.IO.File.OpenRead(txtBrowseFile.Text);
bitmapImage.EndInit();
//now, the Position of the StreamSource is not in the begin of the stream.

image1.Source = bitmapImage;

#endregion
}
The bitmap generated from here is then used in passed to :

public Byte[] BufferFromImage(BitmapImage imageSource)
{
Stream stream = imageSource.StreamSource;
Byte[] buffer = null;
if (stream != null && stream.Length > 0)
{
using (BinaryReader br = new BinaryReader(stream))
{
buffer = br.ReadBytes((Int32)stream.Length);
}
}

return buffer;
}

which returns a byte array and then that byte array is stored in database.

Thanks PrissySC for the reply.Did u get the SDK made for WPF application or got sdk for windows application and u are making it work for wpf.
Actualy i need to make all the biometric integration like fingerprint,iris,facial ,signature ,and voice in wpf application.BUt only fingerprint for a browser application ,and i got its sdk of windows form...should i ask client for wpf sdk..or wpf (xbab) sdk or silverlight (sdk)?Or else i need to use only the sdk provided to me..(i.e. windows)and struggle with it to convert in wpf or silverlight

But its working fine in windows and wpf application.So they says that its working fine.i need to make it work in silverlight
