From aa5b97fa3d8970813c3fd7c9fc88cd38db80482e Mon Sep 17 00:00:00 2001 From: Chris Sherlock Date: Tue, 15 Apr 2014 01:06:48 +1000 Subject: Split outdev5.cxx and outdev6.cxx outdev5.cxx deals with curved shapes, so renamed to curvedshapes.cxx Moved polygon functions to polygon.cxx, transparency functions to transparent.cxx, a few miscellaneous functions to outdev.cxx and as the rest of the functions are wallpaper functions then renamed outdev6.cxx to wallpaper.cxx Change-Id: I62a0b66d4d66740fb5f70ecb558db1ad3bf76eb5 --- vcl/Library_vcl.mk | 6 +- vcl/source/outdev/curvedshapes.cxx | 222 +++++++ vcl/source/outdev/outdev.cxx | 118 ++++ vcl/source/outdev/outdev5.cxx | 222 ------- vcl/source/outdev/outdev6.cxx | 1196 ------------------------------------ vcl/source/outdev/polygon.cxx | 94 +++ vcl/source/outdev/transparent.cxx | 603 ++++++++++++++++++ vcl/source/outdev/wallpaper.cxx | 384 ++++++++++++ 8 files changed, 1424 insertions(+), 1421 deletions(-) create mode 100644 vcl/source/outdev/curvedshapes.cxx delete mode 100644 vcl/source/outdev/outdev5.cxx delete mode 100644 vcl/source/outdev/outdev6.cxx create mode 100644 vcl/source/outdev/wallpaper.cxx diff --git a/vcl/Library_vcl.mk b/vcl/Library_vcl.mk index b1fd7e8d52fe..6851f0cc8b65 100644 --- a/vcl/Library_vcl.mk +++ b/vcl/Library_vcl.mk @@ -234,6 +234,7 @@ $(eval $(call gb_Library_add_exception_objects,vcl,\ vcl/source/gdi/metric \ vcl/source/gdi/octree \ vcl/source/gdi/oldprintadaptor \ + vcl/source/outdev/outdev \ vcl/source/outdev/tworect \ vcl/source/outdev/bezier \ vcl/source/outdev/polygon \ @@ -250,9 +251,8 @@ $(eval $(call gb_Library_add_exception_objects,vcl,\ vcl/source/outdev/polyline \ vcl/source/outdev/hatch \ vcl/source/outdev/gradient \ - vcl/source/outdev/outdev5 \ - vcl/source/outdev/outdev6 \ - vcl/source/outdev/outdev \ + vcl/source/outdev/curvedshapes \ + vcl/source/outdev/wallpaper \ vcl/source/outdev/outdevnative \ vcl/source/outdev/outmap \ vcl/source/gdi/pdfextoutdevdata \ diff --git a/vcl/source/outdev/curvedshapes.cxx b/vcl/source/outdev/curvedshapes.cxx new file mode 100644 index 000000000000..7fe7e684db58 --- /dev/null +++ b/vcl/source/outdev/curvedshapes.cxx @@ -0,0 +1,222 @@ +/* -*- Mode: C++; tab-width: 4; indent-tabs-mode: nil; c-basic-offset: 4 -*- */ +/* + * This file is part of the LibreOffice project. + * + * This Source Code Form is subject to the terms of the Mozilla Public + * License, v. 2.0.
