Detailed Description

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.

void Isis::StretchType::setHistogram ( const Histogram & hist )

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

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.

Parameters

newStretch Stretch to interpret
