I need transfer a bitmap from webservice:
01 - create bitmap;
02 - create filestream
03 - return bitmap - stream
Example webservice:
Public Function Image() As Byte()
Dim Imagem As String
Imagem = "C:\Marcos\winxp.gif"
Dim Img As New Bitmap(Imagem)
'here i modify the bitmap
'Here, i need return modify bitmap to application like stream

Transfer image from webservice

To do this:
The bitmap object has a save method which allows you to save the bitmap to a memory stream:
Dim stream as new memorystream()
bitmap.Save (Stream, System.Drawing.ImageFormat)
the MemoryStream class has a method to return a ByteArray.
stream.ToArray
another choice might be to save the bitmap locally and then to return an http:// url to the image which can then be downloaded in binary instead of XML.
