From e6ff2ebfaa19421c8d932f4d275548156ae2e13c Mon Sep 17 00:00:00 2001 From: Tom Sepez Date: Fri, 24 Aug 2018 21:55:46 +0000 Subject: Rename CFX_DIBSource to CFX_DIBBase. It is not a source from which you can get CFX_DIBs, but rather a base class from which all DIBs inherit. Do the same thing for the CPDF_DIBSource wrapper class. Mechanical change apart from adding a one-line comment in cfx_dibbase.h Change-Id: Id2bde87813ca301d9fafc55ce08d703dfc6a7184 Reviewed-on: https://pdfium-review.googlesource.com/41352 Reviewed-by: Lei Zhang Commit-Queue: Tom Sepez --- core/fpdfapi/render/cpdf_dibsource.h | 163 ----------------------------------- 1 file changed, 163 deletions(-) delete mode 100644 core/fpdfapi/render/cpdf_dibsource.h (limited to 'core/fpdfapi/render/cpdf_dibsource.h') diff --git a/core/fpdfapi/render/cpdf_dibsource.h b/core/fpdfapi/render/cpdf_dibsource.h deleted file mode 100644 index 597390cd18..0000000000 --- a/core/fpdfapi/render/cpdf_dibsource.h +++ /dev/null @@ -1,163 +0,0 @@ -// Copyright 2017 PDFium Authors.
