## 7. Navigation Dialog

### Overview

The Navigation dialog is designed to offer easy movement around the active image if the zoom is set higher than what the image window can display. If this is the case, there is an inversely colored rectangle that shows the location of the current view area in respect to the image. This rectangular outline can be dragged to change the viewing region.

### Activate the dialog

The Navigation window dialog can be called in many ways :

- from the toolbox-menu: File/ Dialogs/ Navigation

- from the image-menu: Dialogs/ Navialog

- from the image-menu: View/ Navigation window, the Shift+Ctrl+N will call the Navigation Window.

- from another dialog-menu: Add Tab/ Navigation

You can access more quickly to it (but without the zoom functions) by clicking on the icon, at the right bottom corner of the image window.

### Using the Navigation Dialog

The slider

  It allows easy zoom level control, more precise than with the Zoom command.

The buttons

  - Zoom Out, Zoom In and Zoom 1:1 are self explanatory.

  - Zoom Fit to Window: After zooming, this button allows to return to the normal size.

  - Shrink Wrap: The whole zoomed image will be displayed in an enlarged image window, if possible.
