Replaced by CImageDecoder::ReductionFactor

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

Description

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

Parameters

const TSize &aOriginalSize A reference to the original size of an item. const TSize &aReducedSize A reference to the new size of an item.

Return value

TInt The reduction factor.

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

Description

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(const TSize &,const TSize &)const to calculate the reduction factor and then use ImageProcessorUtility::NewImageProcessorL(const CFbsBitmap &,TInt,TDisplayMode,TBool)

Parameters

const CFbsBitmap &aBitmap A reference to the bitmap used. const TSize &aImageSize The size of image to use. TDisplayMode aImageDisplayMode The display mode to use. TBool aDisableErrorDiffusion A flag indicating whether error diffusion should be disabled.

Return value

CImageProcessor * A pointer to a fully constructed CImageProcessor derived object.

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

Description

Static factory function for creating instances of CImageProcessor derived classes.

Parameters

const CFbsBitmap &aBitmap A reference to the bitmap used. TInt aReductionFactor The value indicating how much to shrink the bitmap. TDisplayMode aImageDisplayMode The display mode to use. TBool aDisableErrorDiffusion A flag indicating whether error diffusion should be disabled.

Return value

CImageProcessor * A pointer to a fully constructed CImageProcessor derived object.
