In each image, pressing the "View" button will bring up a window that allows changes to the view being displayed:
The "Set Views For" pull-down choice lets the user choose the view for which the rest of the window applies. This allows different views to be used with each data set that is to be shown in the image.
An "original" view shows the slices as they are present in the data as it was loaded from file(s). An "oblique" view is anything else. Pressing the "oblique" button activates other parameters. The preset view buttons switch the parameters in the rest of the window to show the standard orthogonal orientations.
Changing the image size, center, voxel size, scale, and rotation parameters will cause the data to be re-sliced to display that "view". Changing the "First slice" affects how the re-sliced data is saved (when using the "File:Save" menu).
The "show" check boxes allow various things to be turned on and off. This are similar to key presses such as "R" (show outlines) and "T" (Fill Outlines with Color). Note that turning off "show extractable contours" can help in anatomical localization by showing only the ignored contours: anatomy can be marked in orthogonal planes by drawing with an ignored contour, pressing "t" will hide the extractable contours in the main image so the ignored contours can be seen easily.
When the "Always Update" checkbox is not set, you have to press the "Update" button to see changes in the image.
The "Set scales to fit all data" button will set the "Scale Factors" given the rest of the parameters so that all data will fit inside the image.
