From 611d1c523c6872e048ba0f379d116d727a756e1e Mon Sep 17 00:00:00 2001 From: Robert Holcomb Date: Sat, 24 Mar 2007 06:57:29 +0000 Subject: Initial commit. Not in build system so shouldn't interfere with anything at this point. Will commit modified versions of existing files once build system is tested. --- .../nodes/intern/CMP_nodes/CMP_sepcombYUVA.c | 180 +++++++++++++++++++++ 1 file changed, 180 insertions(+) create mode 100644 source/blender/nodes/intern/CMP_nodes/CMP_sepcombYUVA.c (limited to 'source/blender/nodes/intern/CMP_nodes/CMP_sepcombYUVA.c') diff --git a/source/blender/nodes/intern/CMP_nodes/CMP_sepcombYUVA.c b/source/blender/nodes/intern/CMP_nodes/CMP_sepcombYUVA.c new file mode 100644 index 00000000000..6813ffd31a0 --- /dev/null +++ b/source/blender/nodes/intern/CMP_nodes/CMP_sepcombYUVA.c @@ -0,0 +1,180 @@ +/** + * $Id$ + * + * ***** BEGIN GPL LICENSE BLOCK ***** + * + * This program is free software; you can redistribute it and/or + * modify it under the terms of the GNU General Public License + * as published by the Free Software Foundation; either version 2 + * of the License, or (at your option) any later version. + * + * This program 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.
