Detailed Description

template<typename TValue, typename TColorMap>
class DGtal::TickedColorMap< TValue, TColorMap >

Aim: This class adapts any colormap to add "ticks" in the colormap colors.

Description of template class 'TickedColorMap'

Ticks are characterized by a position and a width in the adapted colormap range. When the value falls in a tick, the colormap color is replaced by the color provided in the constructor.

For example, on a colormap, this class can be used to create white ticks with regular spacing, or locate zero-crossing of a curvature map for instance (i.e. with a single tick at zero).

This class is a model of concepts::CColorMap.

Template Parameters

TValue	The type of the range values.
TColorMap	The type of colormap to Adapt (the value type of TColorMap must be TValue).

◆ addRegularTicks()

template<typename TValue , typename TColorMap >

void DGtal::TickedColorMap< TValue, TColorMap >::addRegularTicks	(	const unsigned int	nbTicks,
		const Value	thickness
	)

Add regularly spaced ticks in the range [myMin,myMax].

Parameters

nbTicks	the number of regular ticks.
thickness	ticks thickness.

Referenced by main(), and testCMAP().

◆ addTick()

template<typename TValue , typename TColorMap >

void DGtal::TickedColorMap< TValue, TColorMap >::addTick	(	const Value	position,
		const Value	thickness
	)

Add a tick at a given position of the range [myMin, myMax].

Parameters

position	tick position.
thickness	tick thickness.

◆ colormap()

template<typename TValue , typename TColorMap >

ColorMap* DGtal::TickedColorMap< TValue, TColorMap >::colormap ( ) const

◆ finalize()

template<typename TValue , typename TColorMap >

void DGtal::TickedColorMap< TValue, TColorMap >::finalize ( )

Referenced by main(), testCMAP(), and testTickedColorMap().

◆ isValid()

template<typename TValue , typename TColorMap >

bool DGtal::TickedColorMap< TValue, TColorMap >::isValid ( ) const
