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.

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

newStretch Stretch to interpret
