Unigine.Plugins.SpiderVision.MasksData Class
This class stores data on all masks created for the viewport and provides the interface for configuring each mask.
The mask is an arbitrary shape filled by a selected color that allows cutting out selected areas on the image rendered in the viewport.
This object is accessible via the corresponding method of the ViewportData class.
The mask data are stored in the configuration file.
MasksData Class
Properties
bool Enabled#
The value indicating if masks rendering is enabled.
int NumMasks#
The total number of masks in the configuration.
Event EventChanged#
The event triggered on changing masks data. You can subscribe to events via
Connect() and unsubscribe via Disconnect(). You can also use EventConnection and
EventConnections classes for convenience (see examples below).
Notice
The event handler signature is as follows: myhandler()For more details see the Event Handling article.
Usage Example
Source code (C#)
// implement the Changed event handler
void changed_event_handler()
{
Log.Message("\Handling Changed event\n");
}
//////////////////////////////////////////////////////////////////////////////
// 1. Multiple subscriptions can be linked to an EventConnections instance
// class that you can use later to remove all these subscriptions at once
//////////////////////////////////////////////////////////////////////////////
// create an instance of the EventConnections class
EventConnections changed_event_connections = new EventConnections();
// link to this instance when subscribing to an event (subscription to various events can be linked)
MasksData.EventChanged.Connect(changed_event_connections, changed_event_handler);
// other subscriptions are also linked to this EventConnections instance
// (e.g. you can subscribe using lambdas)
MasksData.EventChanged.Connect(changed_event_connections, () => {
Log.Message("Handling Changed event lambda\n");
}
);
// later all of these linked subscriptions can be removed with a single line
changed_event_connections.DisconnectAll();
//////////////////////////////////////////////////////////////////////////////
// 2. You can subscribe and unsubscribe via the handler function directly
//////////////////////////////////////////////////////////////////////////////
// subscribe to the Changed event with a handler function
MasksData.EventChanged.Connect(changed_event_handler);
// remove subscription to the Changed event later by the handler function
MasksData.EventChanged.Disconnect(changed_event_handler);
//////////////////////////////////////////////////////////////////////////////
// 3. Subscribe to an event and unsubscribe later via an EventConnection instance
//////////////////////////////////////////////////////////////////////////////
// define a connection to be used to unsubscribe later
EventConnection changed_event_connection;
// subscribe to the Changed event with a lambda handler function and keeping the connection
changed_event_connection = MasksData.EventChanged.Connect(() => {
Log.Message("Handling Changed event lambda\n");
}
);
// ...
// you can temporarily disable a particular event connection
changed_event_connection.Enabled = false;
// ... perform certain actions
// and enable it back when necessary
changed_event_connection.Enabled = true;
// ...
// remove the subscription later using the saved connection
changed_event_connection.Disconnect();
//////////////////////////////////////////////////////////////////////////////
// 4. Ignoring Changed events when necessary
//////////////////////////////////////////////////////////////////////////////
// you can temporarily disable the event to perform certain actions without triggering it
MasksData.EventChanged.Enabled = false;
// ... actions to be performed
// and enable it back when necessary
MasksData.EventChanged.Enabled = true;Members
