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.

| Stretch Isis::LinearStretchType::getStretch | ( | ) | [virtual] |
Returns the current stretch object.
Reimplemented from Isis::StretchType.
References Isis::StretchType::p_stretch.
| void Isis::StretchType::setHistogram | ( | const Histogram & | hist | ) | [virtual, inherited] |
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.

| 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.
