Did you try to use L_SetBitmapRgnFromMask? Did you face problems? If yes, please give me more details about it.

Here's a sample code from our help file:

L_INT SetBitmapRgnFromMaskExample(pBITMAPHANDLE pBitmap)
{
   L_INT nRet;
   BITMAPHANDLE MaskBitmap; /* Bitmap handle that holds the mask bitmap */

   nRet = L_LoadBitmap (TEXT("C:\\Program Files\\LEAD Technologies\\LEADTOOLS 15\\Images\\MASK.TIF"), &MaskBitmap, sizeof(BITMAPHANDLE), 1, ORDER_BGR, NULL, NULL );
   if(nRet != SUCCESS)
      return nRet;
   nRet = L_SetBitmapRgnFromMask ( pBitmap, NULL, &MaskBitmap, L_RGN_SET );
   if(nRet != SUCCESS)
   {
      if(MaskBitmap.Flags.Allocated)
         L_FreeBitmap(&MaskBitmap);
      return nRet;
   }
   if(MaskBitmap.Flags.Allocated)
      L_FreeBitmap(&MaskBitmap);
   return SUCCESS;
}
