NewImageProcessorExtensionL ( const CFbsBitmap &, TInt, TDisplayMode, TBool )

IMPORT_C CImageProcessorExtension *	NewImageProcessorExtensionL	(	const CFbsBitmap &	aBitmap,
			TInt	aReductionFactor,
			TDisplayMode	aImageDisplayMode,
			TBool	aDisableErrorDiffusion
		)	[static]

Static factory function for creating instances of CImageProcessorExtension derived classes.

Parameters
aBitmap	A reference to the bitmap used.
aReductionFactor	The value indicating how much to shrink the bitmap.
aImageDisplayMode	The display mode to use.
aDisableErrorDiffusion	A flag indicating whether error diffusion should be disabled.

Return Value: A pointer to a fully constructed CImageProcessorExtension derived object.

NewImageProcessorL ( const CFbsBitmap &, const TSize &, TDisplayMode, TBool )

IMPORT_C CImageProcessor *	NewImageProcessorL	(	const CFbsBitmap &	aBitmap,
			const TSize &	aImageSize,
			TDisplayMode	aImageDisplayMode,
			TBool	aDisableErrorDiffusion
		)	[static]

Static factory function for creating instances of CImageProcessor derived classes. This fuction is deprecated. It is recommended for plugin writers to use default implementation of CImageReadCodec::ReductionFactor to calculate the reduction factor and then use NewImageProcessorL(const CFbsBitmap& aBitmap,TInt aReductionFactor,TDisplayMode aImageDisplayMode, TBool aDisableErrorDiffusion)

Deprecated

Replaced by CImageReadCodec::ReductionFactor & NewImageProcessorL(const CFbsBitmap& aBitmap,TInt aReductionFactor,TDisplayMode aImageDisplayMode, TBool aDisableErrorDiffusion)

Parameters
aBitmap	A reference to the bitmap used.
aImageSize	The size of image to use.
aImageDisplayMode	The display mode to use.
aDisableErrorDiffusion	A flag indicating whether error diffusion should be disabled.

Return Value: A pointer to a fully constructed CImageProcessor derived object.

NewImageProcessorL ( const CFbsBitmap &, TInt, TDisplayMode, TBool )

IMPORT_C CImageProcessor *	NewImageProcessorL	(	const CFbsBitmap &	aBitmap,
			TInt	aReductionFactor,
			TDisplayMode	aImageDisplayMode,
			TBool	aDisableErrorDiffusion
		)	[static]

Static factory function for creating instances of CImageProcessor derived classes.

Parameters
aBitmap	A reference to the bitmap used.
aReductionFactor	The value indicating how much to shrink the bitmap.
aImageDisplayMode	The display mode to use.
aDisableErrorDiffusion	A flag indicating whether error diffusion should be disabled.

Return Value: A pointer to a fully constructed CImageProcessor derived object.

ReductionFactor ( const TSize &, const TSize & )

IMPORT_C TInt	ReductionFactor	(	const TSize &	aOriginalSize,
			const TSize &	aReducedSize
		)	[static]

Static function to calculate a reduction factor based on the input parameters. This function is deprecated. It is recommended to use CImageDecoder::ReductionFactor or CImageReadCodec::ReductionFactor(for Plugin writers only) to calculate the reduction factor and then use CImageDecoder::ReducedSize to find the size of the decoded bitmap.

Deprecated

Replaced by CImageDecoder::ReductionFactor

Parameters
aOriginalSize	A reference to the original size of an item.
aReducedSize	A reference to the new size of an item.

Return Value: The reduction factor.
