Constructor & Destructor Documentation

◆ LogRangeMapper()

LogRangeMapper::LogRangeMapper	(	int	minpos,
		int	maxpos,
		float	minval,
		float	maxval,
		QString	m_unit = `""`,
		bool	inverted = `false`
	)

Map values in range minval->maxval into integer range minpos->maxpos such that logs of the values are mapped linearly.

minval must be greater than zero, and minval and minpos must be less than maxval and maxpos respectively. If inverted is true, the range will be mapped "backwards" (minval to maxpos and maxval to minpos).

◆ getPositionForValue()

int LogRangeMapper::getPositionForValue ( float value ) const

virtual

Return the position that maps to the given value, rounding to the nearest position and clamping to the minimum and maximum extents of the mapper's positional range.

◆ getPositionForValueUnclamped()

int LogRangeMapper::getPositionForValueUnclamped ( float value ) const

virtual

Return the position that maps to the given value, rounding to the nearest position, without clamping.

That is, whatever mapping function is in use will be projected even outside the minimum and maximum extents of the mapper's positional range. (The mapping outside that range is not guaranteed to be exact, except if the mapper is a linear one.)

◆ getValueForPositionUnclamped()

float LogRangeMapper::getValueForPositionUnclamped ( int position ) const

Return the value mapped from the given positionq, without clamping.

That is, whatever mapping function is in use will be projected even outside the minimum and maximum extents of the mapper's value range. (The mapping outside that range is not guaranteed to be exact, except if the mapper is a linear one.)
