Properties:
| Name | Type | Description |
|---|---|---|
placeholder |
String
|

Object
|
A Longdo Map object that will be working in-sync with this panorama view. (default: null) |
showPath |
Boolean
|
Whether paths that represent available panorama lines should be drawn on map. (default: false) |
getLength |
Boolean
|
Normally API will only download paths data from server if 'showPath' option is set to true.
