PushFixedState Method

Summary

Temporarily disables the fixed state of every AnnObject in the AnnContainer.

Syntax

C++

public virtual int PushFixedState()

  
Public Overridable Function PushFixedState() As Integer

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

using Leadtools; 
using Leadtools.Annotations; 
using Leadtools.WinForms; 
 
// This sample paints annotations (both 'fixed' and non'fixed) at a zoom factor of 2 
// on the Graphics object g 
private void AnnContainer_PushFixedState(Graphics graphics, AnnContainer annContainer) 
{ 
   Matrix transformContainer = annContainer.Transform; 
   Matrix transformOriginal = annContainer.Transform.Clone(); 
 
   // Temporarily disable 'fixed' annotations for painting 
   annContainer.PushFixedState(); 
 
   // Paint the container at 2x 
   Matrix transformZoom2x = new Matrix(2, 0, 0, 2, 0, 0); 
   transformContainer.Multiply(transformZoom2x); 
   annContainer.Draw(graphics); 
 
   // Restore original container transform 
   annContainer.Transform = transformOriginal; 
 
   // Enable 'fixed' annotions 
   annContainer.PopFixedState(); 
}
