WriteableBitmap Methods

The WriteableBitmap type exposes the following members.

  Name Description
Public method AddDirtyRect Specifies the area of the bitmap that changed.
Public method 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.)
Public method 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.)
Public method 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.)
Public method 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.)
Public method CheckAccess Determines whether the calling thread has access to this DispatcherObject. (Inherited from DispatcherObject.)
Public method ClearValue(DependencyProperty) Clears the local value of a property. The property to be cleared is specified by a DependencyProperty identifier. (Inherited from DependencyObject.)
Public method ClearValue(DependencyPropertyKey) Clears the local value of a read-only property. The property to be cleared is specified by a DependencyPropertyKey. (Inherited from DependencyObject.)
Public method Clone Creates a modifiable clone of this WriteableBitmap, making deep copies of this object's values. When copying dependency properties, this method copies resource references and data bindings (but they might no longer resolve) but not animations or their current values.
Public method CloneCurrentValue Creates a modifiable clone of this ByteAnimationUsingKeyFrames object, making deep copies of this object's current values. Resource references, data bindings, and animations are not copied, but their current values are.
Public method CoerceValue 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.)
Public method CopyPixels(Array, Int32, Int32) Copies the bitmap pixel data into an array of pixels with the specified stride, starting at the specified offset. (Inherited from BitmapSource.)
Public method CopyPixels(Int32Rect, Array, Int32, Int32) Copies the bitmap pixel data within the specified rectangle into an array of pixels that has the specified stride starting at the specified offset. (Inherited from BitmapSource.)
Public method CopyPixels(Int32Rect, IntPtr, Int32, Int32) Copies the bitmap pixel data within the specified rectangle (Inherited from BitmapSource.)
Public method Equals Determines whether a provided DependencyObject is equivalent to the current DependencyObject. (Inherited from DependencyObject.)
Public method Freeze() Makes the current object unmodifiable and sets its IsFrozen property to true. (Inherited from Freezable.)
Public method GetAnimationBaseValue Returns the non-animated value of the specified DependencyProperty. (Inherited from Animatable.)
Public method GetAsFrozen Creates a frozen copy of the Freezable, using base (non-animated) property values. Because the copy is frozen, any frozen sub-objects are copied by reference. (Inherited from Freezable.)
Public method GetCurrentValueAsFrozen Creates a frozen copy of the Freezable using current property values. Because the copy is frozen, any frozen sub-objects are copied by reference. (Inherited from Freezable.)
Public method GetHashCode Gets a hash code for this DependencyObject. (Inherited from DependencyObject.)
Public method GetLocalValueEnumerator Creates a specialized enumerator for determining which dependency properties have locally set values on this DependencyObject. (Inherited from DependencyObject.)
Public method GetType Gets the Type of the current instance. (Inherited from Object.)
Public method GetValue Returns the current effective value of a dependency property on this instance of a DependencyObject. (Inherited from DependencyObject.)
Public method InvalidateProperty Re-evaluates the effective value for the specified dependency property (Inherited from DependencyObject.)
Public method Lock Reserves the back buffer for updates.
Public method ReadLocalValue Returns the local value of a dependency property, if it exists. (Inherited from DependencyObject.)
Public method SetCurrentValue Sets the value of a dependency property without changing its value source. (Inherited from DependencyObject.)
Public method SetValue(DependencyProperty, Object) Sets the local value of a dependency property, specified by its dependency property identifier. (Inherited from DependencyObject.)
Public method SetValue(DependencyPropertyKey, Object) Sets the local value of a read-only dependency property, specified by the DependencyPropertyKey identifier of the dependency property. (Inherited from DependencyObject.)
Protected method ShouldSerializeProperty Returns a value that indicates whether serialization processes should serialize the value for the provided dependency property. (Inherited from DependencyObject.)
Public method ToString() Creates a string representation of this object based on the current culture. (Inherited from ImageSource.)
Public method ToString(IFormatProvider) Creates a string representation of this object based on the IFormatProvider passed in. If the provider is null, the CurrentCulture is used. (Inherited from ImageSource.)
Public method TryLock Attempts to lock the bitmap, waiting for no longer than the specified length of time.
Public method Unlock Releases the back buffer to make it available for display.
Public method VerifyAccess Enforces that the calling thread has access to this DispatcherObject. (Inherited from DispatcherObject.)
Public method WritePixels(Int32Rect, Array, Int32, Int32) Updates the pixels in the specified region of the bitmap.
Public method WritePixels(Int32Rect, IntPtr, Int32, Int32) Updates the pixels in the specified region of the bitmap.
Public method WritePixels(Int32Rect, Array, Int32, Int32, Int32) Updates the pixels in the specified region of the bitmap.
Public method WritePixels(Int32Rect, IntPtr, Int32, Int32, Int32, Int32) Updates the pixels in the specified region of the bitmap.
