The following example shows how to save the currently loaded workflow image using a Stream. In this example, a SaveFileDialog is created to prompt the user for the filename of the image to save. A FileStream object is then created using the filename and then passed to the SaveWorkflowImage method.

Public Sub SaveWorkflowImageImportsStream()

    Dim SaveFileDialog As New SaveFileDialog()
    SaveFileDialog.Filter = "Bitmap Files|*.bmp"
    If SaveFileDialog.ShowDialog() = DialogResult.OK Then
        Using fileStream As New FileStream(SaveFileDialog.FileName, FileMode.Create)
            Me.workflowView.SaveWorkflowImage(fileStream, ImageFormat.Bmp)
        End Using
    End If
End Sub
