Example

This example creates an array of selected items and rotates each one.
Note that this can also be done simply by setting a flag in L_AnnRotate.

L_INT AnnGetSelectItemsExample(HANNOBJECT hContainer /* Container annotation object */) 
{ 
   L_INT       nRet; 
   L_UINT      uSelectCount;  /* Number of objects selected */ 
   pHANNOBJECT pAnnArray;     /* Pointer to an array of annotation objects */ 
   L_HGLOBAL   hAnnArray;     /* Handle for memory management */ 
   L_UINT      i;             /* Loop counter */ 
 
   /* Get the number of objects selected */ 
   nRet = L_AnnGetSelectCount(hContainer, &uSelectCount); 
   if (nRet != SUCCESS) 
      return nRet; 
 
   /* Allocate and lock a storage for the object handles */ 
   hAnnArray = GlobalAlloc(GPTR, sizeof(HANNOBJECT) * uSelectCount); 
   pAnnArray = (pHANNOBJECT)GlobalLock(hAnnArray); 
 
   /* Fill the array of selected objects */ 
   nRet = L_AnnGetSelectItems(hContainer, pAnnArray); 
   if (nRet != SUCCESS) 
      return nRet; 
 
   /* Rotate each selected object */ 
   for (i = 0; i < uSelectCount; i++) 
   { 
      nRet = L_AnnRotate(pAnnArray[i], 90, 0, 0); 
      if (nRet != SUCCESS) 
         return nRet; 
   } 
 
   /* Free the memory */ 
   GlobalUnlock(hAnnArray); 
   GlobalFree(hAnnArray); 
 
   return SUCCESS; 
}
