From b1fbbe23b43f56da9cbd515e92ef44a8f7b31aa2 Mon Sep 17 00:00:00 2001 From: Emmanuele Bassi Date: Wed, 28 Sep 2011 15:54:32 +0100 Subject: [PATCH] Revert "Add lightness, brightness, and contrast effects" Discussed a bit with Neil, and I might have jumped the gun a little. We might want a different API for 1.10. See comment 12 on: https://bugzilla.gnome.org/show_bug.cgi?id=656156 This reverts commit 4829ae1c79f1ae60d562621b81a7be800e0697bb. --- clutter/Makefile.am | 6 - clutter/clutter-brightness-effect.c | 380 --------------------------- clutter/clutter-brightness-effect.h | 63 ----- clutter/clutter-contrast-effect.c | 395 ----------------------------- clutter/clutter-contrast-effect.h | 63 ----- clutter/clutter-invert-lightness-effect.c | 243 ------------------ clutter/clutter-invert-lightness-effect.h | 57 ----- doc/reference/clutter/clutter-docs.xml.in | 3 - doc/reference/clutter/clutter-sections.txt | 47 ---- doc/reference/clutter/clutter.types | 3 - 10 files changed, 1260 deletions(-) delete mode 100644 clutter/clutter-brightness-effect.c delete mode 100644 clutter/clutter-brightness-effect.h delete mode 100644 clutter/clutter-contrast-effect.c delete mode 100644 clutter/clutter-contrast-effect.h delete mode 100644 clutter/clutter-invert-lightness-effect.c delete mode 100644 clutter/clutter-invert-lightness-effect.h diff --git a/clutter/Makefile.am b/clutter/Makefile.am index cf37c4d..d9b81a8 100644 --- a/clutter/Makefile.am +++ b/clutter/Makefile.am @@ -71,7 +71,6 @@ source_h = \ $(srcdir)/clutter-blur-effect.h \ $(srcdir)/clutter-box.h \ $(srcdir)/clutter-box-layout.h \ - $(srcdir)/clutter-brightness-effect.h \ $(srcdir)/clutter-cairo-texture.h \ $(srcdir)/clutter-child-meta.h \ $(srcdir)/clutter-click-action.h \ @@ -81,7 +80,6 @@ source_h = \ $(srcdir)/clutter-colorize-effect.h \ $(srcdir)/clutter-constraint.h \ $(srcdir)/clutter-container.h \ - $(srcdir)/clutter-contrast-effect.h \ $(srcdir)/clutter-deform-effect.h \ $(srcdir)/clutter-deprecated.h \ $(srcdir)/clutter-desaturate-effect.h \ @@ -98,7 +96,6 @@ source_h = \ $(srcdir)/clutter-gesture-action.h \ $(srcdir)/clutter-group.h \ $(srcdir)/clutter-input-device.h \ - $(srcdir)/clutter-invert-lightness-effect.h \ $(srcdir)/clutter-interval.h \ $(srcdir)/clutter-keysyms.h \ $(srcdir)/clutter-keysyms-compat.h \ @@ -161,7 +158,6 @@ source_c = \ $(srcdir)/clutter-blur-effect.c \ $(srcdir)/clutter-box.c \ $(srcdir)/clutter-box-layout.c \ - $(srcdir)/clutter-brightness-effect.c \ $(srcdir)/clutter-cairo-texture.c \ $(srcdir)/clutter-child-meta.c \ $(srcdir)/clutter-click-action.c \ @@ -170,7 +166,6 @@ source_c = \ $(srcdir)/clutter-colorize-effect.c \ $(srcdir)/clutter-constraint.c \ $(srcdir)/clutter-container.c \ - $(srcdir)/clutter-contrast-effect.c \ $(srcdir)/clutter-deform-effect.c \ $(srcdir)/clutter-desaturate-effect.c \ $(srcdir)/clutter-device-manager.c \ @@ -187,7 +182,6 @@ source_c = \ $(srcdir)/clutter-gesture-action.c \ $(srcdir)/clutter-group.c \ $(srcdir)/clutter-input-device.c \ - $(srcdir)/clutter-invert-lightness-effect.c \ $(srcdir)/clutter-interval.c \ $(srcdir)/clutter-keysyms-table.c \ $(srcdir)/clutter-layout-manager.c \ diff --git a/clutter/clutter-brightness-effect.c b/clutter/clutter-brightness-effect.c deleted file mode 100644 index 9891156..0000000 --- a/clutter/clutter-brightness-effect.c +++ /dev/null @@ -1,380 +0,0 @@ -/* - * Clutter. - * - * An OpenGL based 'interactive canvas' library. - * - * Copyright (C) 2010, 2011 Inclusive Design Research Centre, OCAD University. - * - * This library is free software; you can redistribute it and/or - * modify it under the terms of the GNU Lesser General Public - * License as published by the Free Software Foundation; either - * version 2 of the License, or (at your option) any later version. - * - * This library is distributed in the hope that it will be useful, - * but WITHOUT ANY WARRANTY; without even the implied warranty of - * MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE.
