Detailed Description

This handles the advanced sawtooth stretch.

The sawtooth stretch is useful for highlighting things like craters. This highlights areas of DNs - for example it can highlight all of the DNs based on how close to the mean they are (user guesses the mean from the histogram). It can also highlight DNs as they differ from the mean. Anyhow, it existed in a form before so this class was needed to encapsulate it. I'm not sure what the original request for this stretch type derived from.

Constructor & Destructor Documentation

◆ SawtoothStretchType()

Isis::SawtoothStretchType::SawtoothStretchType	(	const Histogram &	hist,

This initializes a sawtooth stretch type.

Parameters

hist
stretch
name
color

◆ ~SawtoothStretchType()

Isis::SawtoothStretchType::~SawtoothStretchType ( )

Destructor.

Member Function Documentation

◆ createStretchTable()

QTableWidget * Isis::StretchType::createStretchTable ( )

protectedinherited

This creates the stretch pairs table.

Returns: QTableWidget*

◆ deleteFromCube

void Isis::StretchType::deleteFromCube ( )

signalinherited

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

◆ getStretch()

CubeStretch Isis::SawtoothStretchType::getStretch ( )

virtual

Gets the CubeStretch for this Sawtooth Stretch.

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::SawtoothStretchType::setStretch ( Stretch newStretch )

virtual

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

It is required that a stretch that represents a sawtooth stretch always translate into itself and does not cause a stretchChanged(). To ensure this the sliders have been restricted to not be ambiguous.

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

Parameters

newStretch Stretch to interpret

Implements Isis::StretchType.
