BitmapImage.EndInit Method ()

 

Signals the end of the BitmapImage initialization.

Namespace:   System.Windows.Media.Imaging
Assembly:  PresentationCore (in PresentationCore.dll)

Public Sub EndInit

Exception Condition
InvalidOperationException

The UriSource or StreamSource properties are null.

-or-

The EndInit method is called without first calling BeginInit.

Property initialization must be done between BeginInit and EndInit calls. Once the BitmapImage has been initialized, property changes are ignored.

The following example demonstrates how to initialize a BitmapImage with a set of properties by using the BeginInit and EndInit methods.

' Define a BitmapImage.
Dim myImage As New Image()
Dim bi As New BitmapImage()

' Begin initialization.
bi.BeginInit()

' Set properties.
bi.CacheOption = BitmapCacheOption.OnDemand
bi.CreateOptions = BitmapCreateOptions.DelayCreation
bi.DecodePixelHeight = 125
bi.DecodePixelWidth = 125
bi.Rotation = Rotation.Rotate90
MessageBox.Show(bi.IsDownloading.ToString())
bi.UriSource = New Uri("smiley.png", UriKind.Relative)

' End initialization.
bi.EndInit()
myImage.Source = bi
myImage.Stretch = Stretch.None
myImage.Margin = New Thickness(5)
