SetAutoCamera Method

In This Topic

Sets the auto camera for the map frame display constraints. This method must be called on the MCT. Use QueuedTask.Run.

Syntax

C#
Visual Basic (Declaration)

public void SetAutoCamera( 
   CIMAutoCamera autoCamera
)

Public Sub SetAutoCamera( _
   ByVal autoCamera As CIMAutoCamera _
)

Parameters

autoCamera: The auto camera to set

Exceptions

Exception	Description
ArcGIS.Core.CalledOnWrongThreadException	This method or property must be called within the lambda passed to QueuedTask.Run.
System.InvalidOperationException	Empty map frame
System.InvalidOperationException	Map frame contains a scene
System.InvalidOperationException	Map frame is linked to a map series
System.ArgumentException	Invalid auto camera

Remarks

Use the auto camera to set map frame display constraints. Display constraints are used to set limits on the map extent within the map frame. Refer to Map frame constraints in the Pro product help for more information on constraints. Attempting to set a CIMAutoCamera will fail with an exception in the following situations:
o The map frame is empty or does not contain a 2D map.
o The map frame is currently linked to a layout map series. Refer to IsMapSeriesMapFrame.
o The autoCamera is not valid. Use ValidateAutoCamera.

Example

SetAutoCameraNone
