BitmapImage.EndInit Method ()

 

Signals the end of the BitmapImage initialization.

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

public void 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.
Image myImage = new Image();
BitmapImage bi = 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);
