From 67476e5ef6f122f39f547f5a14b84e9306fa136c Mon Sep 17 00:00:00 2001 From: Henrique Nakashima Date: Wed, 28 Jun 2017 14:37:33 -0400 Subject: Converting CFX_ByteTextBuf to ostringstream in cpvt_generateap.cpp https://pdfium-review.googlesource.com/c/7033/ contains the changes in the corpus tests expected pngs. They are imperceptible and due to a difference in float rounding when writing the appearance stream.
