Set visibility limits for images and hotspots
In Deep Zoom Composer, you can specify whether the size of an image or a hotspot determines its visibility. For example, you might want to create the effect of zooming in toward a specific neighborhood from outer space, and passing through a cloud layer. To accomplish this, you would place a layer containing an image of a cloud on top of a layer containing an aerial image of houses on a street. You would then set the maximum visibility limit for the cloud image, so that the cloud image becomes invisible when you zoom in far enough, thus revealing the image with the houses underneath.
You can also set a minimum visibility limit, which will cause an image to become invisible when you zoom out far enough, and therefore reveal any layers that are lower in the stacking order.
If you set a visibility limit for any image or hotspot, you will have to export your composition as a composition, not as a collection. Therefore, you won't be able to specify a template other than Deep Zoom Navigation (default).
To set a visibility limit for an image or a hotspot
In the Compose workspace, resize and position the image or hotspot whose visibility limit you want to set, making sure that it is in a layer that is higher in the stacking order than the layer of the image or hotspot that you want to hide and then reveal.
Right-click the image or hotspot, click Set Visibility Limits, and then do one of the following:
To set a maximum visibility limit, so the image or hotspot in the layer below is revealed when you zoom in, click Set this as maximum.
To set a minimum visibility limit, so the image or hotspot in the layer below is revealed when you zoom out, Set this as minimum.
You can also set visibility limits manually in the Properties panel, by typing a number in the Min box or the Max box.
You can set visibility limits for more than one image or hotspot at a time by selecting multiple images and hotspots in the Images panel or on the artboard, and then, in the Properties panel, typing a number in the Min box or the Max box. However, if you do this, the new visibility limit for the multiple images and hotspots will overwrite any previous visibility limits that the individual images and hotspots had before.
You can test your visibility limits by clicking the Preview button in the Export workspace, and then, in the Deep Zoom Composer preview window, zooming in and out on each image or hotspot for which you set a visibility limit.
