Try the functions below (untested, but modified from a couple of functions I use in one of my apps).

Private Sub saveRotatedImage
    Private bm As Bitmap
    Private input As InputStream
    Private output As OutputStream
    Private buffer() As Byte
   
   
    Try
        input = File.OpenInput([Image Directory], [Image Name])
        bm.Initialize2(input)
        Private bm2 As Bitmap = rotateImage(bm, [rotation value])
        output.InitializeToBytesArray(0)
        bm2.WriteToStream(output, 100, "PNG")
        buffer = output.ToBytesArray
        output = File.OpenOutput([Output Directory], [Output Image Name], False)
        output.WriteBytes(buffer, 0, buffer.Length)
        output.Flush
        output.Close
    Catch
        Log(LastException)
    End Try
End Sub

Public Sub rotateImage(Original As Bitmap, rotateBy) As Bitmap
    Private b2 As BitmapExtended
    
    b2.Initialize("")
    Return b2.rotateBitmap(Original, rotateBy)
   
End Sub

No need to use BitmapExtended.

Dim bm2 As Bitmap = bm.Rotate(90)
