Changes
A HotSpot is a single data object that sits on a layer and typically has a visual representation, such as the value of a property it represents.
===How to enable Hotspotting in the UI===
In order to enable the hotspotting feature in the newest [[Version_4.0_(WinX)#4_0|4.0 release]] you have to do the following.
Go to the UBIKDocumentArea.xaml and add the 'HotspotButtonVisibility="Visible"' line to the UBIKPdfViewer.

===Merge/Flatten===
Like with annotations, hotspots on a document can also be merged/flattened/burnt in. However, due to the complexity and the customizability of the hotspot UI, it's impossible to precisely store and restore the same UI on the server. Therefore, a thumbnail image of the hotspot is generated to represent how that hotspot looks. This is important since the thumbnail will be what then gets flattened in the PDF.
{{Hint|By default, the thumbnail of a hotspot is updated on the client whenever necessary (e.g. size changed, content changed, etc.). But there's an attribute named "AutoLock" on the UBIKPdfViewer which prevents a user from editing the hotspot once it's saved. And naturally, there won't be any more thumbnail updates for such locked hotspots.}}
===AutoLock===
When set to true, all hotspots will be locked once saved. Otherwise, they remain open to edits. If unspecified, it defaults to false.
