Gets or sets the transformation that is applied to the brush. This transformation is applied after the brush's output has been mapped and positioned. (Inherited from Brush.)
Gets or sets the brush's content.
There are two ways to specify the Visual content of a .
When you define a new Visual for a and that Visual is a UIElement (such as a panel or control), the layout system runs on the UIElement and its child elements when the AutoLayoutContent property is set to true. However, the root UIElement is essentially isolated from the rest of the system; styles, storyboards, and external layout can't permeate this boundary. Therefore, you should explicitly specify the size of the root UIElement, because its only parent is the and therefore it cannot automatically size itself to the area being painted. For more information about layout in Windows Presentation Foundation (WPF), see the Layout.
Updates to the visual tree of a BitmapEffect is in the brush's parent chain. You can workaround this limitation by forcing an update of the scene on the object above the effect. You can call InvalidateVisual or include an animation to force a scene update.will not propagate if a
Freezable Features: Because it inherits from the Freezable class, the class provides several special features: objects can be declared as and shared among multiple objects. For more information about the different features provided by Freezable objects, see the Freezable Objects Overview.
