When images are read as described above, they are automatically displayed in the active graphics window. This is the default behavior, but the automatic display of images can be suppressed if desired, for example, to speed up computationally intensive programs.
Initially, new images are fitted into the graphics window at a 1:1 aspect ratio with unused bars on the left and right side. The aspect ratio will be preserved when resizing the graphics window. Using the tool bar of the graphics window you can easily zoom the image or change the resize mode from the default Keep Aspect Ratio behavior. Furthermore, you can change the default resize behavior under Edit ▹ Preferences ▹ General Options. This default resize behavior applies to graphics windows that are opened via menu, Visialization ▹ Open Graphics Window... or Window ▹ Open Graphics Window.
An iconic view of the loaded image is also displayed in the variable window. When the image is cleared in the graphics window, the image can always be restored by double-clicking the corresponding icon in the variable window. See also section Displaying Iconic Variables.
