public virtual void RenderLayers( 
   LeadRectD clipRect, 
   AnnLayerCollection layers, 
   AnnContainer container, 
   bool runMode 
) 
Public Overridable Sub RenderLayers( _ 
   ByVal clipRect As LeadRectD, _ 
   ByVal layers As AnnLayerCollection, _ 
   ByVal container As AnnContainer, _ 
   ByVal runMode As Boolean _ 
)  
public void renderLayers(LeadRectD clipRect, AnnLayerCollection layers, AnnContainer container, boolean runMode) 
public:  
   virtual void RenderLayers( 
      LeadRectD^ clipRect, 
      AnnLayerCollection^ layers, 
      AnnContainer^ container, 
      bool runMode 
   ) 

Parameters

clipRect
The destination clip rectangle Leadtools.LeadRectD in container coordinates. The engine will only render into this area. Pass LeadRectD.Empty to not use a clip rectangle.

layers
The layers to render.

container
The owner container.

runMode
true to render this container in run mode; otherwise, false.

Remarks

This method uses the mapper in container to calculate the destination rectangle and any other transform to be applied.

The value of runModecontrols whether this method renders the thumbs, selection objects and other parts used in design mode of the annotation objects as follows:

  • To render the current state of the designers "as is", pass false. An example is performing automation in a viewer.

  • To burn the annotations to an image, pass true. Most of the time design mode parts are not required in run mode.
