Detailed Description

template<class F, bool NORM = false, bool SIGN = false>
class drain::image::UnaryFunctorOp< F, NORM, SIGN >

Class for using simple function objects (like std::functor) for sequential pixel iteration.

! \template F - unary (single-parameter) functor \template NORM - normalize to 0...1 (unsigned) and -1...1 (signed) \template SIGN - select signed, else unsigned

Constructor & Destructor Documentation

◆ UnaryFunctorOp()

UnaryFunctorOp	(	bool	adaptParams = `true`,
		bool	adoptLimit = `true`
	)

inline

Parameters

adaptParameters	- add all the parameters of the functors to this op's parameters
adaptLimit	- add LIMIT option to visible parameters

Member Function Documentation

◆ getDstConf()

void getDstConf	(	const ImageConf &	src,
		ImageConf &	dst
	)		const

inlineprotectedvirtual

Given source image, determine respective dest image configuration.

This default implementations

changes type and scaling only if either is undefined in dst.
copies geometry and coordinate policy of src.

Reimplemented from ImageOp.

◆ traverseChannel()

void traverseChannel	(	const Channel &	src,
		Channel &	dst
	)		const

virtual

Process the image.

In future versions there may dedicated processing for integral and floatimg-point base types. (If some of images are double, then

Unlimited, unscaled, ie. "direct". This option may be sufficient if dst is double, for example.

Reimplemented from ImageOp.

Reimplemented in RadarFunctorOp< F >.
