Example

This example converts the annotation object (rectangle, ellipse and hilite) into a region once the user draws them

#ifdef LImageViewerChild 
class LImageViewerChild :public LImageViewerCell 
{ 
   virtual L_INT AnnotationCreatedCallBack(L_INT    nCellIndex, 
   L_INT    nSubCellIndex, 
   L_UINT   uAnnotationType); 
}; 
#endif 
L_INT LImageViewerChild::AnnotationCreatedCallBack(L_INT    nCellIndex, 
L_INT    nSubCellIndex, 
L_UINT   uAnnotationType) 
{ 
   UNREFERENCED_PARAMETER(nCellIndex); 
   switch(uAnnotationType) 
   { 
      case ANNOBJECT_RECT: 
      case ANNOBJECT_ELLIPSE: 
      case ANNOBJECT_HILITE: 
      AnnToRgn(nSubCellIndex, L_RGN_OR, TRUE, 0); 
      break; 
   } 
   return SUCCESS; 
} 
L_INT LImageViewer_AnnotationCreatedCallbacksExample(LImageViewerCell& ImageViewerCell) 
{ 
   ImageViewerCell.EnableAnnotationCreatedCallBack(TRUE); 
   return SUCCESS; 
}
