From 10a7ddb596f0089ba12d0db29b5752a61919a208 Mon Sep 17 00:00:00 2001 From: Henrique Nakashima Date: Wed, 11 Jul 2018 20:55:02 +0000 Subject: Store property name for marked content with an indirect dict. The name of the property is now stored in the CPDF_ContentMarkItem, which will be needed to properly write back these content marks after a change in the stream.
