Create a new Bitmap object with the value of width and height.

PictureBox1.Image = New Bitmap(100, 100)

Answer 3

Suppose you have two buttons on the interface to clear the image and redraw image, you can use following functions on their click handlers.

VB

Private Sub ClearImage()
        PictureBox1.Image = Nothing
    End Sub

    Private Sub SetImage(ByVal img As Image)
        PictureBox1.Image = img
    End Sub

C#

public void ClearImage()
{
 PictureBox1.Image = null;
}

public void SetImage( Image img)
{
 PictureBox1.Image = img;
}
