Detailed Description

This handles the advanced binary stretch.

The binary stretch consists off DNs being "ON" or "OFF" (0 or 255). This is useful for finding DNs in a certain range. Because all stretches consist of lines with a slope, we can't actually have a binary stretch. This, however, makes a stretch as close to binary as it can.

Constructor & Destructor Documentation

◆ BinaryStretchType()

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

This constructs a binary stretch type.

Parameters
hist
stretch
name
color

References Isis::StretchType::p_cubeHist, Isis::StretchType::p_mainLayout, Isis::Histogram::Percent(), and setStretch().

◆ ~BinaryStretchType()

Isis::BinaryStretchType::~BinaryStretchType ( )

Destroys the binary stretch.

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::BinaryStretchType::getStretch ( )
virtual

Gets the CubeStretch for this Binary 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::BinaryStretchType::setStretch ( Stretch newStretch)
virtual

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

It is required that a stretch that represents a binary 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
newStretchStretch to interpret
