ADJUSTING THE MAP DISPLAY

The VMX300(-E) client provides the following methods for changing the view of a map:

•Zoom buttons

•Previous View button

•Predeﬁned views

The Zoom In button works two ways:

•Zoom in incrementally

•Zoom in on a selected part of the map

Incremental: To zoom in incrementally:

1. Click the Zoom In button and position the pointer over the map. The pointer appears as a magnifying glass with a plus sign in it.

2. Click the part of the map you want to zoom in on. The map appears at about 110% of its previous scale.

Selected area: To zoom in on a particular part of the map:

1. Click the Zoom In button and position the pointer over the map. The pointer appears as a magnifying glass with a plus sign in it.

2. Position the pointer at one corner of the area you want to magnify. Press and hold the left mouse button.

3. Drag the pointer to the opposite corner of the area you want to magnify. A rectangle delineating the area to magnify appears.

4. Release the mouse button. The selected area appears as large as possible to ﬁt within the display area.

NOTE: You must click the Zoom In button each time you want to zoom in.

The Zoom-Out button decreases the size of the displayed map by about 10%. To zoom out, click the Zoom Out button.

NOTE: You must click the Zoom Out button each time you want to zoom out.

The Previous View button retrieves whatever was last displayed in the map viewport, allowing you to step back through the history of the

viewport. Every time you change the display in the viewport, either by loading a different map or predeﬁned view, or by zooming or scrolling,

VMX300(-E) records the view.

To display the previous view, click the Previous View button. Continue clicking the Previous View button until you have stepped back to the desired

view.

Predeﬁned views allow you to display a particular view of the currently loaded map by selecting a previously saved view from the predeﬁned

views drop-down list.

VMX300(-E) provides two default predeﬁned views, Fit to Screen and One to One. As well, your system administrator can create custom pre-

deﬁned views. Predeﬁned views created and saved by the system administrator are listed at the bottom of the predeﬁned views drop-down list.

If you adjust the view so it does not coincide with a predeﬁned view, Custom View appears in the drop-down list.

Fit to screen: Fit to Screen displays the loaded map as large as possible to ﬁt within the current size of the map viewport.

One to one: One to One displays the loaded map at its actual size. If the map viewport is not large enough to display the entire map at its actual

size, a portion of the map will be displayed.
