Метод	Описание
CloneCore ( System.Windows.Freezable source ) : void	Copies data into a cloned instance. When Freezable is cloned, WPF will make deep clones of all writable, locally-set properties including expressions. The property's base value is copied -- not the current value. WPF skips read only DPs. If you derive from this class and have additional non-DP state that should be transfered to copies, you should override the CopyCommon method.
CloneCurrentValueCore ( System.Windows.Freezable source ) : void	Copies data into a cloned instance. When a Freezable's "current value" is cloned, WPF will make deep clones of the "current values" of all writable, locally-set properties. This has the effect of resolving expressions to their values. WPF skips read only DPs. If you derive from this class and have additional non-DP state that should be transfered to copies, you should override the CopyCommon method.
CopyCore ( CustomBitmap original, bool useCurrentValue, bool willBeFrozen ) : void	Copies data into a cloned instance. Override this method if you have additional non-DP state that should be transfered to clones.
CopyPixelsCore ( System.Windows.Int32Rect sourceRect, int stride, int bufferSize, IntPtr buffer ) : void	Requests pixels from this BitmapSource. This is the main image processing routine. It instructs the BitmapSource instance to produce pixels according to its algorithm - this may involve decoding a portion of a JPEG stored on disk, copying a block of memory, or even analytically computing a complex gradient. The algorithm is completely dependent on the implementation. Implementation of this method must only write to the first (rc.Width*PixelFormat.BitsPerPixel+7)/8 bytes of each line of the output buffer (in this case, a line is a consecutive string of "stride" bytes).
CreateInstanceCore ( ) : System.Windows.Freezable	Creates an instance of a CustomBitmap. The default implementation uses reflection to create a new instance of this type.

Описание методов

CloneCore() защищенный закрытый Метод

Copies data into a cloned instance.

When Freezable is cloned, WPF will make deep clones of all writable, locally-set properties including expressions. The property's base value is copied -- not the current value. WPF skips read only DPs. If you derive from this class and have additional non-DP state that should be transfered to copies, you should override the CopyCommon method.

protected final CloneCore ( System.Windows.Freezable source ) : void
source	System.Windows.Freezable	/// The original instance to copy data from. ///
Результат	void

CloneCurrentValueCore() защищенный закрытый Метод

Copies data into a cloned instance.

When a Freezable's "current value" is cloned, WPF will make deep clones of the "current values" of all writable, locally-set properties. This has the effect of resolving expressions to their values. WPF skips read only DPs. If you derive from this class and have additional non-DP state that should be transfered to copies, you should override the CopyCommon method.

protected final CloneCurrentValueCore ( System.Windows.Freezable source ) : void
source	System.Windows.Freezable	/// The original instance to copy data from. ///
Результат	void

CopyCore() защищенный Метод

Copies data into a cloned instance.

Override this method if you have additional non-DP state that should be transfered to clones.

protected CopyCore ( CustomBitmap original, bool useCurrentValue, bool willBeFrozen ) : void
original	CustomBitmap	/// The original instance to copy data from. ///
useCurrentValue	bool	/// Whether or not to copy the current value of expressions, or the /// expressions themselves. ///
willBeFrozen	bool	/// Indicates whether or not the clone will be frozen. If the /// clone will be immediately frozen, there is no need to clone /// data that is already frozen, you can just share the instance. ///
Результат	void

CopyPixels() публичный закрытый Метод

Requests pixels from this BitmapSource.

Derived classes must override CopyPixelsCommon to implement custom logic.

public final CopyPixels ( Array pixels, int stride, int offset ) : void
pixels	System.Array	/// The destination array of pixels. ///
stride	int	/// The stride of the destination array. ///
offset	int	/// The starting index within the destination array to copy to. ///
Результат	void

CopyPixels() публичный закрытый Метод

Requests pixels from this BitmapSource.

Derived classes must override CopyPixelsCommon to implement custom logic.

public final CopyPixels ( System.Windows.Int32Rect sourceRect, Array pixels, int stride, int offset ) : void
sourceRect	System.Windows.Int32Rect	/// The rectangle of pixels to copy. ///
pixels	System.Array	/// The destination array of pixels. ///
stride	int	/// The stride of the destination array. ///
offset	int	/// The starting index within the destination array to copy to. ///
Результат	void

CopyPixels() публичный закрытый Метод

Requests pixels from this BitmapSource.

Derived classes must override CopyPixelsCommon to implement custom logic.

Результат	void

CopyPixelsCore() защищенный Метод

Requests pixels from this BitmapSource.

This is the main image processing routine. It instructs the BitmapSource instance to produce pixels according to its algorithm - this may involve decoding a portion of a JPEG stored on disk, copying a block of memory, or even analytically computing a complex gradient. The algorithm is completely dependent on the implementation. Implementation of this method must only write to the first (rc.Width*PixelFormat.BitsPerPixel+7)/8 bytes of each line of the output buffer (in this case, a line is a consecutive string of "stride" bytes).

protected CopyPixelsCore ( System.Windows.Int32Rect sourceRect, int stride, int bufferSize, IntPtr buffer ) : void
sourceRect	System.Windows.Int32Rect
stride	int	/// Defines the count of bytes between two vertically adjacent /// pixels in the output buffer. ///
bufferSize	int	/// The size ///
buffer	System.IntPtr	/// The caller controls the memory management and must provide an /// output buffer of sufficient size to complete the call based on /// the width, height and pixel format of the bitmap and the /// sub-rectangle provided to the copy method. ///
Результат	void

CreateInstanceCore() защищенный Метод

Creates an instance of a CustomBitmap.

The default implementation uses reflection to create a new instance of this type. Derived classes may override this method if they wish to provide a more performant implementation, or if their type does not have a public default constructor.

GetAsFrozenCore() защищенный закрытый Метод

Copies data into a cloned instance.

Freezable.GetAsFrozen is semantically equivalent to Freezable.Clone().Freeze(), except that you can avoid copying any portions of the Freezable graph which are already frozen. If you derive from this class and have additional non-DP state that should be transfered to copies, you should override the CopyCommon method.

GetCurrentValueAsFrozenCore() защищенный закрытый Метод

Copies data into a cloned instance.

Freezable.GetCurrentValueAsFrozen is semantically equivalent to Freezable.CloneCurrentValue().Freeze(), except that WPF will avoid copying any portions of the Freezable graph which are already frozen. If you derive from this class and have additional non-DP state that should be transfered to copies, you should override the CopyCommon method.
