AvsFilter_CorrectGamma

This is Filter Equivalent. This function may be present in generated code, but should not be used in hand-written code.

Performs gamma correction.

Applications: Image enhancement for human perception. For computer vision consider LogarithmImage.

Syntax

void avs::AvsFilter_CorrectGamma
(
	AvsFilters_ImagePointTransformsState& ioState,
	const avl::Image& inImage,
	atl::Optional<const avl::Region&> inRoi,
	float inValue,
	avl::Image& outImage
)

Parameters

	Name	Type	Range	Default	Description
	ioState	AvsFilters_ImagePointTransformsState&			Object used to maintain state of the function.
	inImage	const Image&			Input image
	inRoi	Optional<const Region&>		NIL	Range of pixels to be processed
	inValue	float	0.01 - 8.0	2.0f	Gamma coefficient, where 1.0 is neutral
	outImage	Image&			Output image
