Detailed Description

This handles the advanced linear stretch.

The linear stretch is what happens without the advanced stretch tool. This is useful for visualizing and making adjustments of the linear stretch with a histogram of the data.

Constructor & Destructor Documentation

◆ LinearStretchType()

Isis::LinearStretchType::LinearStretchType	(	const Histogram &	hist,
		const Stretch &	stretch,
		const QString &	name,
		const QColor &	color )

This constructs a linear stretch type.

Parameters

hist
stretch
name
color

References Isis::StretchType::p_mainLayout, and setStretch().

◆ ~LinearStretchType()

Isis::LinearStretchType::~LinearStretchType ( )

Destructor.

Member Function Documentation

◆ createStretchTable()

QTableWidget * Isis::StretchType::createStretchTable ( )

protectedinherited

This creates the stretch pairs table.

Returns: QTableWidget*

Referenced by Isis::StretchType::StretchType().

◆ deleteFromCube

void Isis::StretchType::deleteFromCube ( )

signalinherited

Referenced by Isis::StretchType::StretchType().

◆ getStretch()

CubeStretch Isis::LinearStretchType::getStretch ( )

virtual

Returns the CubeStretch for this LinearStretch.

Returns: CubeStretch

Reimplemented from Isis::StretchType.

References Isis::StretchType::p_stretch.

◆ loadStretch

void Isis::StretchType::loadStretch ( )

signalinherited

Referenced by Isis::StretchType::StretchType().

◆ saveToCube

void Isis::StretchType::saveToCube ( )

signalinherited

Emitted when a new Stretch object is available.

Referenced by Isis::StretchType::StretchType().

◆ setHistogram()

void Isis::StretchType::setHistogram ( const Histogram & hist )

virtualinherited

This should be called when the visible area changes.

It updates the graph and calls setStretch() so that the children have a chance to update their GUI elements too.

Parameters

hist

References Isis::StretchType::p_cubeHist, Isis::StretchType::p_graph, Isis::StretchType::p_stretch, Isis::HistogramWidget::setHistogram(), and Isis::StretchType::setStretch().

◆ setStretch()

void Isis::LinearStretchType::setStretch ( Stretch newStretch )

virtual

Given an arbitrary stretch, this will re-interpret it, as best as possible, into a linear stretch.

It is required that a stretch that represents a linear stretch always translate into itself and does not cause a stretchChanged().

It is necessary to always update slider positions in this method even if the stretch did not change.

Parameters

newStretch Stretch to interpret
