Les propriétés Source ou Transform sont null.

- ou -

La transformation n'est pas une transformation orthogonale.

- ou -

La méthode EndInit() est appelée sans préalablement appeler BeginInit().

Exemples

L’exemple suivant montre comment initialiser un TransformedBitmap avec un ensemble de propriétés à l’aide des BeginInit méthodes et EndInit .

// 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()

Remarques

L’initialisation de propriété doit être effectuée entre BeginInit les appels et .EndInit Une fois que le TransformedBitmap a été initialisé, les modifications de propriété sont ignorées.
