Use the members of this enumeration to set the value of the SizeMode property of the PictureBox.

The following code example demonstrates the use of the SizeMode property. To run this example, paste the following code into a Windows Form and call the InitializePictureBoxAndButton method from the form's constructor or Load-event handling method.

Dim PictureBox1 As New PictureBox()
Dim WithEvents Button1 As New Button

<STAThread()> _
Public Shared Sub Main()
    Application.Run(New Form1())
End Sub

Private Sub InitializePictureBoxAndButton()

    Button1.Location = New Point(175, 20)
    Button1.Text = "Stretch"

    ' Set the size of the PictureBox control.
    Me.PictureBox1.Size = New System.Drawing.Size(140, 140)

    'Set the SizeMode to center the image.
    Me.PictureBox1.SizeMode = PictureBoxSizeMode.CenterImage

    ' Set the border style to a three-dimensional border.
    Me.PictureBox1.BorderStyle = BorderStyle.Fixed3D

    ' Set the image property.
    Me.PictureBox1.Image = New Bitmap(GetType(Button), "Button.bmp")
End Sub

Private Sub Button1_Click(ByVal sender As System.Object, _
    ByVal e As System.EventArgs) Handles Button1.Click
    ' Set the SizeMode property to the StretchImage value.  This
    ' will enlarge the image as needed to fit into
    ' the PictureBox.
    PictureBox1.SizeMode = PictureBoxSizeMode.StretchImage
End Sub
