rotating an image, by not using the defaulted upper left corner for rotation point

[jkw119]

If anyone can help me out here, i would really appreciate it. I am trying to do a relatively simple task -> Rotate a Picture. Which works fine. But the problem is, my code uses the upper left corner to rotate the image. Is it possible to change that to the middle, or the origin, so that i can rotate the picture from the center. If so, how is this done? Here is the sample code, basically it is a panel on a form, and this is it's paint event. It loads a picture from the programs bin folder. Thanks alot...

Private Sub TextArea_Paint(ByVal sender As Object, ByVal e As System.Windows.Forms.PaintEventArgs) Handles TextArea.Paint
 
        Dim sa As System.Drawing.Size
        sa = TextArea.Size
 
        Dim middle As New Point(sa.Width / 4, sa.Height / 3)
        e.Graphics.TranslateTransform(middle.X, middle.Y)
 
        'Apply all transforms....
        e.Graphics.RotateTransform(45) 'angle to rotate
 
        Dim bmp As New Bitmap("sample.jpg")
        e.Graphics.DrawImage(bmp, 0, 0)
 
    End Sub
