Tiling an image in GDI+

[JezB]

I'm trying to write a routine to tile a given image in a given rectangle:

public static void DrawTiledImage(Graphics g, Image image, Rectangle r)
{
ImageAttributes ia = new ImageAttributes();
ia.SetWrapMode(WrapMode.Tile);
g.DrawImage(image, r, 0, 0, image.Width, image.Height,
GraphicsUnit.Pixel, ia);
}

Problem is this seems to be stretching the image not tiling it. What am I
doing wrong ?

Private m_Brush As TextureBrush

Private Sub Form1_Load(...) Handles MyBase.Load
m_Brush = New TextureBrush(New Bitmap("C:\WINDOWS\Angler.bmp"))
End Sub

Protected Overrides Sub OnPaintBackground(ByVal e As PaintEventArgs)
MyBase.OnPaintBackground(e)
e.Graphics.FillRectangle(m_Brush, Me.ClientRectangle)
End Sub

Just draw the image using a TextureBrush and the tiling will happen as if by
magic...
