Figure 29: View Selector
After an image has been opened, the application window looks similar to figure 30 below. The four main
components of the application window are the options window, the image, the colour bar and the thermal
histogram. Overlaid on the histogram is the movable span selector which adjusts the level and span of the
thermal image. The span selector can be moved by clicking in the middle of the histogram and dragging left
or right. The span can be increased and decreased by clicking towards the ends of the span selector (where the
max and min values of the span are displayed) and dragging left or right. The span can be automatically reset
by double-clicking in the middle of the span selector.
