Sestavení:
PresentationCore.dll

Signalizuje konec BitmapImage inicializace.

public:

[System.Security.SecurityCritical]
public void EndInit ();
public void EndInit ();
[<System.Security.SecurityCritical>]
abstract member EndInit : unit -> unit
override this.EndInit : unit -> unit
abstract member EndInit : unit -> unit
override this.EndInit : unit -> unit
Public Sub EndInit ()

Implementuje

EndInit()
Atributy
SecurityCriticalAttribute

Výjimky

InvalidOperationException

Vlastnosti Source jsou Transform null.

-nebo- Transformace není orthogonální transformace.

-nebo- Metoda EndInit() se volá bez prvního volání BeginInit().

Příklady

Následující příklad ukazuje, jak inicializovat TransformedBitmap se sadou vlastností pomocí BeginInit a EndInit metod.

// Create the new BitmapSource that will be used to scale the size of the source.
TransformedBitmap myRotatedBitmapSource = new TransformedBitmap();

// BitmapSource objects like TransformedBitmap can only have their properties
// changed within a BeginInit/EndInit block.
myRotatedBitmapSource.BeginInit();

// Use the BitmapSource object defined above as the source for this BitmapSource.
// This creates a "chain" of BitmapSource objects which essentially inherit from each other.
myRotatedBitmapSource.Source = myBitmapImage;

// Flip the source 90 degrees.
myRotatedBitmapSource.Transform = new RotateTransform(90);
myRotatedBitmapSource.EndInit();

' Create the new BitmapSource that will be used to scale the size of the source.
Dim myRotatedBitmapSource As New TransformedBitmap()

' BitmapSource objects like TransformedBitmap can only have their properties
' changed within a BeginInit/EndInit block.
myRotatedBitmapSource.BeginInit()

' Use the BitmapSource object defined above as the source for this BitmapSource.
' This creates a "chain" of BitmapSource objects which essentially inherit from each other.
myRotatedBitmapSource.Source = myBitmapImage

' Flip the source 90 degrees.
myRotatedBitmapSource.Transform = New RotateTransform(90)
myRotatedBitmapSource.EndInit()

Poznámky

Inicializace vlastností musí být provedena mezi BeginInit voláními a EndInit voláními. TransformedBitmap Po inicializaci se změny vlastností ignorují.
