Figure 13.21.  Navigation Dialog

Navigation Dialog

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.

2.6.1.  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/ Navigation

  • 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.

2.6.2.  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.

  • Adjust the zoom ratio so that the image becomes fully visible: The zoom ratio is adjusted so that the whole image becomes visible in the the window as it is.

  • Adjust the zoom ratio so that the window is used optimally: The image size and the zoom are adjusted so that the image is fully displayed with the lesser zoom.

  • Reduce the image window to the size of the image display : Restaure the image window to the size which allows the image to be fully displayed with the zoom unchanged.
