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.

◆ 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

◆ 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

Implements Isis::StretchType.
