I have a project where I have to display an image that is extracted from within an xml file. Can someone explain how I can load the string into a rasterimageviewer. What I am doing currently is wrting the image to a file then loading that file which is obviously not very efficient, my current code is below

Dim BitmapData() As Byte
BitmapData = Convert.FromBase64String(imageText)
Dim streamBitmap As MemoryStream = New System.IO.MemoryStream(BitmapData)
Dim bitImage As Image = Image.FromStream(streamBitmap)

'write image

' Load an image into the viewer
Dim codecs As New RasterCodecs
RasterImageViewer1.Image = codecs.Load("label.png")

One you get the data into a MemoryStream, you don't need to save it to
disk.  Just call one of the overloads of the RasterCodecs.Load method that takes a Stream and load it directly.
