Открытые методы

Метод	Описание
ApplyFilter ( FastBitmap bitmap ) : void	Applies the filter to the specified bitmap. This method first calls ImageReplacementFilter.GetDestinationDimensions(FastBitmap, out Int32, out Int32) to calculate the size of the destination image. Then it calls ImageReplacementFilter.ApplyFilter(FastBitmap, DrawingContext, int, int) which is where the overridden class implements its filter algorithm.

Метод	Описание
ApplyFilter ( FastBitmap source, System.Windows.Media.DrawingContext dc, int width, int height ) : void	When overridden in a derived class, applies the filter to the specified source.
CleanUpDrawingVisual ( FastBitmap source, System.Windows.Media.DrawingVisual drawingVisual ) : void	Inherited classes can use this to clean up the supplied DrawingVisual. For example, ShaderEffectFilter disposes the shader effect.
ConfigureDrawingVisual ( FastBitmap source, System.Windows.Media.DrawingVisual drawingVisual ) : void	Inherited classes can use this to configure the supplied DrawingVisual. For example, RotationFilter sets the BitmapScalingMode render option.
GetDestinationDimensions ( FastBitmap source, int &width, int &height ) : bool	When overridden in a derived class, returns the dimensions of the output image.
OnBeginApplyFilter ( FastBitmap bitmap ) : void	This method allows derived classes to perform actions prior to the filter being applied.
OnEndApplyFilter ( ) : void	This method allows derived classes to perform actions after the filter has been applied.

Описание методов

ApplyFilter() публичный закрытый Метод

Applies the filter to the specified bitmap. This method first calls ImageReplacementFilter.GetDestinationDimensions(FastBitmap, out Int32, out Int32) to calculate the size of the destination image. Then it calls ImageReplacementFilter.ApplyFilter(FastBitmap, DrawingContext, int, int) which is where the overridden class implements its filter algorithm.

public final ApplyFilter ( FastBitmap bitmap ) : void
bitmap	SoundInTheory.DynamicImage.Util.FastBitmap	/// Image to apply the to. ///
Результат	void

ApplyFilter() защищенный абстрактный Метод

When overridden in a derived class, applies the filter to the specified source.

protected abstract ApplyFilter ( FastBitmap source, System.Windows.Media.DrawingContext dc, int width, int height ) : void
source	SoundInTheory.DynamicImage.Util.FastBitmap	The source image.
dc	System.Windows.Media.DrawingContext	A object, created from .
width	int
height	int
Результат	void

CleanUpDrawingVisual() защищенный Метод

Inherited classes can use this to clean up the supplied DrawingVisual. For example, ShaderEffectFilter disposes the shader effect.

protected CleanUpDrawingVisual ( FastBitmap source, System.Windows.Media.DrawingVisual drawingVisual ) : void
source	SoundInTheory.DynamicImage.Util.FastBitmap
drawingVisual	System.Windows.Media.DrawingVisual
Результат	void

ConfigureDrawingVisual() защищенный Метод

Inherited classes can use this to configure the supplied DrawingVisual. For example, RotationFilter sets the BitmapScalingMode render option.

protected ConfigureDrawingVisual ( FastBitmap source, System.Windows.Media.DrawingVisual drawingVisual ) : void
source	SoundInTheory.DynamicImage.Util.FastBitmap
drawingVisual	System.Windows.Media.DrawingVisual
Результат	void

GetDestinationDimensions() защищенный абстрактный Метод

When overridden in a derived class, returns the dimensions of the output image.

protected abstract GetDestinationDimensions ( FastBitmap source, int &width, int &height ) : bool
source	SoundInTheory.DynamicImage.Util.FastBitmap	The source image.
width	int	The desired width of the output image.
height	int	The desired height of the output image.
Результат	bool

OnBeginApplyFilter() защищенный Метод

This method allows derived classes to perform actions prior to the filter being applied.

protected OnBeginApplyFilter ( FastBitmap bitmap ) : void
bitmap	SoundInTheory.DynamicImage.Util.FastBitmap
Результат	void

OnEndApplyFilter() защищенный Метод

This method allows derived classes to perform actions after the filter has been applied.

protected OnEndApplyFilter ( ) : void
Результат	void
