Hi, an example showing how to take an array of byte

and save it to a IO.MemoryStream and then use this stream to create the RasterImage object,

all this without passing through an intermediate Image object would

help me A LOT :) ....

thankx....

Hello,

If the byte array contains a complete image file (including headers), you can use the following code:
+--------------------------+
...
Dim MyImage As IRasterImage
fs.Read(byte1, 0, fs.Length)
' bytes and an array of type byte
Dim ms As MemoryStream
ms = New MemoryStream
ms.Write(byte1, 0, byte1.Length)
ms.Seek(0, SeekOrigin.Begin)
MyImage = codecs.Load(ms, 0, ms.Length)
...
+--------------------------+

If the array contains only image pixel data (raw image), you also use the Load method, but you will need to specify the raw format using the _codecs.Options.Load.Format property, and handle the _codecs.LoadInformation event. This is explained in the help file and shown in the main VB.NET demo.

Thanks,
