Snapshots

RadWebCam allows you to snapshot the currently displayed video feed. This can be done via the "Take snapshot" button of the control, or the TakeSnapshot method. This will fire the SnapshotTaken event where you can get the Image object.

Taking a snapshot in code

• C#
• VB.NET

        public WebCamFeatures()
        {
            InitializeComponent();

            this.radWebCam1.SnapshotTaken += radWebCam1_SnapshotTaken;
        }

        private void radWebCam1_SnapshotTaken(object sender, Telerik.WinControls.UI.SnapshotTakenEventArgs e)
        {
            Image snapshot = e.Snapshot;
            // here you save the image to a file, in memory, or to show it in the UI 
        }

        private void OnTakeSnapshot(object sender, EventArgs e)
        {
            this.radWebCam1.TakeSnapshot();
        }

    Public Sub New()
        InitializeComponent()
        AddHandler Me.RadWebCam1.SnapshotTaken, AddressOf radWebCam1_SnapshotTaken
    End Sub

    Private Sub radWebCam1_SnapshotTaken(ByVal sender As Object, ByVal e As Telerik.WinControls.UI.SnapshotTakenEventArgs)
        Dim snapshot As Image = e.Snapshot
    End Sub

    Private Sub OnTakeSnapshot(ByVal sender As Object, ByVal e As EventArgs)
        Me.RadWebCam1.TakeSnapshot()
    End Sub

Preview Snapshots

By default, when you take a snapshot a preview of the image will be shown. To disable this, set the PreviewSnapshots property to false.

• C#
• VB.NET

        this.radWebCam1.PreviewSnapshots = false;

        Me.RadWebCam1.PreviewSnapshots = False

You can indicate if the snapshot preview is displayed via the IsPreviewingSnapshot property of RadWebCam.
