#include <ImFusion/GUI/HistogramOverlay.h>
ViewOverlay to show an intensity histogram of the first shown image in a SliceView. More...
Inheritance diagram for HistogramOverlay:ViewOverlay to show an intensity histogram of the first shown image in a SliceView.
Additionally, it shows a the visual representation of the datasets window/level as configured in its DisplayOptions2d. Basic mouse interaction allows for manipulating window/level as well for configuring the overlay itself through a context menu.
