The following example shows how to respond to the BackgroundImageLayoutChanged event in an event handler. This example requires that you have a RectangleShape control named RectangleShape1 on a form.

private void rectangleShape1_BackgroundImageLayoutChanged(object sender, 
    System.EventArgs e)
    // If the image is centered, check its size.
    if (rectangleShape1.BackgroundImageLayout == ImageLayout.Center)
        SizeF imageSize;
        imageSize = rectangleShape1.BackgroundImage.PhysicalDimension;
        // If the image is smaller than the shape, change the BackColor.
        if (imageSize.Height < rectangleShape1.ClientSize.Height || 
            imageSize.Width < rectangleShape1.ClientSize.Width)
            rectangleShape1.BackColor = Color.Black;
