When a series is selected in the Browser, its first image is displayed in the Viewer. The Viewer has a viewing area on top (1), and a control panel at the bottom. Users can use the appropriate scrollers ((2)) to iterate over frames of an open image or images of a series. The left part of the control panel shows a graph of image data statistics (3) and controls to adjust maximum/minimum/contrast/brightness of the image (4). On the right, a mini map of the image (6) and controls for zooming (5).
