From f55e72e0476e5f5699b887099f213982e207afd0 Mon Sep 17 00:00:00 2001 From: Dan Sinclair Date: Thu, 13 Jul 2017 14:53:28 -0400 Subject: Cleanup CPDF_RenderOptions colour members. MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit This CL removes the fore/back colours in favour of just using the colours inline and converts the m_ColorMode to an enum.
