Inheritance diagram for HistogramDlg:

Detailed Description

A user interface dialog that presents the user with histogram information in graph form and allows the user to generate nodes on it to produce a piecewise linear stretch.

This results in contrast stretching in the views. The user can select between the different color channels in the image or all at the same time.
