Detailed Description

template<class afptype, class afptypesimd, class adith = CImageResizerDithererDefDIL< afptype, afptypesimd >>
class avir::fpclass_def_dil< afptype, afptypesimd, adith >

Floating-point processing definition and abstraction class for de-interleaved processing.

This class defines several constants and typedefs that point to classes that should be used by the image resizing algorithm. This implementation points to de-interleaved processing classes.

Template Parameters

afptype	Floating point type to use for storing intermediate data and variables. SIMD types should not be used.
afptypesimd	SIMD type used to perform processing.
adith	Ditherer class to use during processing.

typedef adith avir::fpclass_def_dil< afptype, afptypesimd, adith >::CDitherer

Ditherer class to use during processing.

typedef CImageResizerFilterStepDIL< fptype, afptypesimd > avir::fpclass_def_dil< afptype, afptypesimd, adith >::CFilterStep

Filtering step class to use during processing.

template<class afptype , class afptypesimd , class adith = CImageResizerDithererDefDIL< afptype, afptypesimd >>

typedef afptype avir::fpclass_def_dil< afptype, afptypesimd, adith >::fptype

Floating-point type to use during processing.

template<class afptype , class afptypesimd , class adith = CImageResizerDithererDefDIL< afptype, afptypesimd >>

typedef afptype avir::fpclass_def_dil< afptype, afptypesimd, adith >::fptypeatom

Atomic type "fptype" consists of.

template<class afptype , class afptypesimd , class adith = CImageResizerDithererDefDIL< afptype, afptypesimd >>

const int avir::fpclass_def_dil< afptype, afptypesimd, adith >::elalign = sizeof( afptypesimd ) / sizeof( afptype )

static

Length alignment of arrays of elements. This applies to filters and intermediate buffers: this constant forces filters and scanlines to have a length which is a multiple of this value, for more efficient SIMD implementation.

template<class afptype , class afptypesimd , class adith = CImageResizerDithererDefDIL< afptype, afptypesimd >>

const int avir::fpclass_def_dil< afptype, afptypesimd, adith >::fpalign = sizeof( afptypesimd )

static

Suggested alignment size in bytes. This is not a required alignment, because image resizing algorithm cannot be made to have a strictly aligned data access in all cases (e.g. de-interleaved interpolation cannot perform aligned accesses).

template<class afptype , class afptypesimd , class adith = CImageResizerDithererDefDIL< afptype, afptypesimd >>

const int avir::fpclass_def_dil< afptype, afptypesimd, adith >::fppack = 1

static

The number of atomic types stored in a single "fptype" element.

template<class afptype , class afptypesimd , class adith = CImageResizerDithererDefDIL< afptype, afptypesimd >>

const int avir::fpclass_def_dil< afptype, afptypesimd, adith >::packmode = 1

static

0 if interleaved packing, 1 if de-interleaved.
