#include <avir_dil.h>

Public Types
typedef adith	CDitherer
	Ditherer class to use during processing.
typedef CImageResizerFilterStepDIL< fptype, afptypesimd >	CFilterStep
	Filtering step class to use during processing.
typedef afptype	fptype
	Floating-point type to use during processing.
typedef afptype	fptypeatom
	Atomic type "fptype" consists of.

Static Public Attributes
static const int	elalign = sizeof( afptypesimd ) / sizeof( afptype )
	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.
static const int	fpalign = sizeof( afptypesimd )
	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).
static const int	fppack = 1
	The number of atomic types stored in a single "fptype" element.
static const int	packmode = 1
	0 if interleaved packing, 1 if de-interleaved.

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.
