LEADTOOLS Annotations (Leadtools.Annotations assembly)

PushFixedState Method (AnnContainer)

Show in webframe
Example 





Temporarily disables the fixed state of every AnnObject in the AnnContainer.
Syntax
public virtual int PushFixedState()
'Declaration
 
Public Overridable Function PushFixedState() As Integer
'Usage
 
Dim instance As AnnContainer
Dim value As Integer
 
value = instance.PushFixedState()

            

            
public:
virtual int PushFixedState(); 

Return Value

size of the fixed state stack before the call to PushFixedState
Remarks
Calls AnnObject.PushFixedState on all AnnObject in the AnnContainer. Fixed annotations are independent of the Transform. The result is that they do not scroll or move with the underlying image. For more information, refer to AnnObject.PushFixedState.
Example

   ' Restore original container transform
   annContainer.Transform = transformOriginal

   ' Enable 'fixed' annotions
