Comments

LEADTOOLS continuously updates annotation features. Some of these features change the way annotations look. Other features change the behavior of the user interface (automated mode). To maintain backward compatibility within the v14 series, the new features were disabled by default. To enable these features, call LAnnotation::SetOptions with the desired flags. To get the current options, call the LAnnotation::GetOptions function. For more information, refer to Key Annotation Features.

Example

The following example demonstrates how to enable and disable the new
'side handle' annotation feature in version 14.5. To see how this works,
paste this example into the main annotation demo, draw a rectangle,
and select it before calling this function. The example toggles the feature.

L_INT LAnnotation_SetOptionsExample(LAnnRectangle& annrect) 
{ 
   L_TCHAR *pszMsg = NULL; 
   L_INT nRet = SUCCESS; 
   L_UINT uOptions = 0; 
 
   nRet = annrect.GetOptions(&uOptions); 
   if (nRet != SUCCESS) 
      return nRet; 
 
   if (uOptions & OPTIONS_NEW_SIDE_HANDLES) 
   { 
      uOptions &= ~OPTIONS_NEW_SIDE_HANDLES; 
      pszMsg = TEXT("Draw a rectangular object and select it. Note there are no side handles. Run this example again to enable the side handles."); 
   } 
   else 
   { 
      uOptions |= OPTIONS_NEW_SIDE_HANDLES;  
      pszMsg = TEXT("Draw a rectangular object and select it. Note the side handles. Run this example again to disable the side handles."); 
   } 
 
   nRet = annrect.SetOptions(uOptions); 
   if (nRet != SUCCESS) 
      return  nRet; 
	MessageBox( NULL, pszMsg, TEXT("Notice"), MB_OK); 
	 
	return SUCCESS; 
}
