Specifies how an image is positioned within a PictureBox.
Assembly: System.Windows.Forms (in System.Windows.Forms.dll)
| Member name | Description | |
|---|---|---|
![]() | Normal | The image is placed in the upper-left corner of the PictureBox. The image is clipped if it is larger than the PictureBox it is contained in. |
![]() | StretchImage | The image within the PictureBox is stretched or shrunk to fit the size of the PictureBox. |
| AutoSize | The PictureBox is sized equal to the size of the image that it contains. | |
![]() | CenterImage | The image is displayed in the center if the PictureBox is larger than the image. If the image is larger than the PictureBox, the picture is placed in the center of the PictureBox and the outside edges are clipped. |
| Zoom | The size of the image is increased or decreased maintaining the size ratio. |
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.EnableVisualStyles() Application.Run(New Form1()) End Sub Private Sub InitializePictureBoxAndButton() Me.Controls.Add(PictureBox1) Me.Controls.Add(Button1) 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
