CreateLogarithmLut

Creates Look Up Table for logarithm transformation.

Syntax

void avl::CreateLogarithmLut
(
	atl::real inOffset,
	const atl::Optional<atl::real>& inScale,
	bool inNormalizeZero,
	const avl::PlainType::Type& inOutputType,
	const int inOutputDepth,
	avl::PixelLut& outLut
)

void CreateLogarithmLut
(
	float inOffset,
	float? inScale,
	bool inNormalizeZero,
	AvlNet.PlainType inOutputType,
	int inOutputDepth,
	out AvlNet.PixelLut outLut
)

Parameters

Name	Type	Range	Default
inOffset	real		1.0f
inScale	const Optional<real>&		NIL
inNormalizeZero	bool
inOutputType	const PlainType::Type&
inOutputDepth	const int	1 - 4	1
outLut	PixelLut&

Description

This operation will create LookUp Table with precalculated values of logarithm operation on all pixel values of type defined in inOutputType. Such LUT can be reused across multiple ApplyPixelLut usages. This filter can create LUTs only for following types: INT8, UINT8, INT16, UINT16.

Remarks

Standard operations like PowerImage, CorrectGamma and LogarithmImage for images of type Int32 and Real are available in Image Point Transforms category.
