From 85361b227ad6786d2aeef8409b79a8d077a26ee9 Mon Sep 17 00:00:00 2001 From: Dan Sinclair Date: Mon, 26 Oct 2015 16:14:23 -0400 Subject: Make m_pShadingObj a CPDF_Stream instead of CPDF_Object. This object is required to be a stream and was being converted as such. With the new type checking this caused us to pass a nullptr where previously we'd have, incorrectly, cast a CPDF_Dictionary to a CPDF_Stream. This CL changes the m_pShadingObj to always be a CPDF_Stream. Then, we never go down the bad code path because we check if m_pShadingObj is nullptr earlier and bail out.
