Implements

EndInit()

Attributes: SecurityCriticalAttribute

Exceptions

InvalidOperationException

The Source or Transform properties are null.

-or-

The transform is not an orthogonal transform.

-or-

The EndInit() method is called without first calling BeginInit().

Examples

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

// 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()

Remarks

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