From 618edef2dfea870c34800dbf3f2fd3f7be819300 Mon Sep 17 00:00:00 2001 From: xlou Date: Fri, 12 Oct 2018 23:37:41 +0000 Subject: Add setters/getters for BleedBox and TrimBox. Since BleedBox and TrimBox are supported according to PDF specification, hence added setters and getters to get the value if exists.
