Remarks

The derived classes of TileBrush define the contents of the tiles that you use to paint a region. For example, use the ImageBrush class to paint an area by using an image.

Use a TileBrush to control how you paint an area. For example, Windows Presentation Foundation (WPF) provides several types of brushes:

When you use the TileBrush to paint an area, instead of painting an area by using a single stretched image, you can paint an area by using a series of image tiles that create a pattern.

When you paint an area by using a TileBrush, you use three components: content, tiles, and the output area. The following illustrations show how these three TileBrush components relate to each other.

TileBrush components Components of a TileBrush with a single tile

Components of a tiled TileBrush Components of a TileBrush with a TileMode of Tile

Content: A TileBrush can have different types of content:

You can specify the position and dimensions of TileBrush content by using the Viewbox property.

Tiles: A TileBrush produces one or more tiles. By default, the content of the brush is stretched to fill a single tile and that tile is stretched to fill the output area. The Viewport property is used to specify the size and position of the base tile for the TileBrush. The ViewportUnits property determines whether the size and position of the Viewport are relative to the output area (the default behavior) or whether they are absolute values.

Output Area: The output area is the area that the brush paints, such as the Fill of an Ellipse or the Background of a Button.

Freezable Features

A TileBrush is a Freezable type. For information about Freezable features, such as freezing and cloning, see the Freezable Objects Overview.

Notes to Implementers

When you inherit from the TileBrush class, you must override the CreateInstanceCore() method. For more information about inheriting from Freezable types, see the Freezable Objects Overview.

Methods

ApplyAnimationClock(DependencyProperty, AnimationClock, HandoffBehavior)

Applies an AnimationClock to the specified DependencyProperty. If the property is already animated, the specified HandoffBehavior is used.

(Inherited from Animatable)
ApplyAnimationClock(DependencyProperty, AnimationClock)

Applies an AnimationClock to the specified DependencyProperty. If the property is already animated, the SnapshotAndReplace handoff behavior is used.

(Inherited from Animatable)
BeginAnimation(DependencyProperty, AnimationTimeline, HandoffBehavior)

Applies an animation to the specified DependencyProperty. The animation is started when the next frame is rendered. If the specified property is already animated, the specified HandoffBehavior is used.

(Inherited from Animatable)
BeginAnimation(DependencyProperty, AnimationTimeline)

Applies an animation to the specified DependencyProperty. The animation is started when the next frame is rendered. If the specified property is already animated, the SnapshotAndReplace handoff behavior is used.

(Inherited from Animatable)
CheckAccess()

Determines whether the calling thread has access to this DispatcherObject.

(Inherited from DispatcherObject)
ClearValue(DependencyProperty)

Clears the local value of a property. The property to be cleared is specified by a DependencyProperty identifier.

(Inherited from DependencyObject)
ClearValue(DependencyPropertyKey)

Clears the local value of a read-only property. The property to be cleared is specified by a DependencyPropertyKey.

(Inherited from DependencyObject)
Clone()

Creates a modifiable copy of this TileBrush by making deep copies of its values.

CloneCore(Freezable)

Makes the instance a clone (deep copy) of the specified Freezable using base (non-animated) property values.

(Inherited from Freezable)
CloneCurrentValue()

Creates a modifiable copy of this TileBrush object by making deep copies of its values. This method does not copy resource references, data bindings, or animations, although it does copy their current values.

CloneCurrentValueCore(Freezable)

Makes the instance a modifiable clone (deep copy) of the specified Freezable using current property values.

(Inherited from Freezable)
CoerceValue(DependencyProperty)

Coerces the value of the specified dependency property. This is accomplished by invoking any CoerceValueCallback function specified in property metadata for the dependency property as it exists on the calling DependencyObject.

(Inherited from DependencyObject)
CreateInstance()

Initializes a new instance of the Freezable class.

(Inherited from Freezable)
CreateInstanceCore()

When implemented in a derived class, creates a new instance of the Freezable derived class.

Equals(Object)

Determines whether a provided DependencyObject is equivalent to the current DependencyObject.

(Inherited from DependencyObject)
Freeze()

Makes the current object unmodifiable and sets its IsFrozen property to true.

(Inherited from Freezable)
FreezeCore(Boolean)

GetAnimationBaseValue(DependencyProperty)

Returns the non-animated value of the specified DependencyProperty.
