From 7cf13c9c8b9b69b01e5debb5e8dc8b265983dfa8 Mon Sep 17 00:00:00 2001 From: Wei Li Date: Fri, 19 Feb 2016 11:53:03 -0800 Subject: Remove PageObject's m_Type and add As functions For CPDF_PageObject and its subclasses, remove m_Type and use GetType() instead. Also, add As functions to avoid casting all over the places.
