public:  
   virtual void RenderLayer( 
      LeadRectD^ clipRect, 
      AnnLayer^ layer, 
      AnnContainer^ container, 
      bool runMode 
   ) 

Parameters

clipRect
The destination clip rectangle Leadtools.LeadRectD in container coordinates. The engine will only render into this area. The destination clip rectangle Leadtools.LeadRectD is in container coordinates. The engine will only render into this area. If you do not want to use a clip rectangle, pass Leadtools.LeadRectD.Empty.

layer
The layer 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 runMode controls 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.
