Restrict a Visual Item to a Zoom Range

Use the Visibility property to restrict the display of the visual item to a map's zoom range. By assigning different zoom ranges to different visual items you can change what is displayed as you zoom in and out of the map. For example, you could display an small image (e.g., a well icon) to designate facility locations when zoomed out to a state level, which could then change to display a Canvas object displaying additional facility information as you zoom into a neighborhood where facilities are located.

Note that the:

• Canvas Native view supports all visual items: images, shapes, and objects.

• CygNet TWC web view supports only images.

2. Set the Minimum zoom to 0 and Maximum zoom to 9.
3. Specify the image to display at this zoom range in the Image file path property.

3. Specify the object to display at this zoom range in the Object file path property.
