From 87b313792821cb842fd54b568302b6877c4e53f8 Mon Sep 17 00:00:00 2001 From: Adam Frisby Date: Sat, 3 May 2008 20:00:35 +0000 Subject: * Cleaned up code in Terrain, Tree and Map modules. * Fixed a bug with Terragen loader where it would do bad things on a non 256x256 sized terrain. Now loads the array correctly. * Moved MapImageModule.cs to Modules/World/WorldMap * Changed Location.RegionHandle to use Helpers.GetUlong instead of doing it ourselves. --- .../Modules/World/WorldMap/MapImageModule.cs | 167 +++++++++++++++++++++ 1 file changed, 167 insertions(+) create mode 100644 OpenSim/Region/Environment/Modules/World/WorldMap/MapImageModule.cs (limited to 'OpenSim/Region/Environment/Modules/World/WorldMap/MapImageModule.cs') diff --git a/OpenSim/Region/Environment/Modules/World/WorldMap/MapImageModule.cs b/OpenSim/Region/Environment/Modules/World/WorldMap/MapImageModule.cs new file mode 100644 index 0000000..8ebe33e --- /dev/null +++ b/OpenSim/Region/Environment/Modules/World/WorldMap/MapImageModule.cs @@ -0,0 +1,167 @@ +/* + * Copyright (c) Contributors, http://opensimulator.org/ + * See CONTRIBUTORS.TXT for a full list of copyright holders. + * + * Redistribution and use in source and binary forms, with or without + * modification, are permitted provided that the following conditions are met: + * * Redistributions of source code must retain the above copyright + * notice, this list of conditions and the following disclaimer. + * * Redistributions in binary form must reproduce the above copyright + * notice, this list of conditions and the following disclaimer in the + * documentation and/or other materials provided with the distribution. + * * Neither the name of the OpenSim Project nor the + * names of its contributors may be used to endorse or promote products + * derived from this software without specific prior written permission. + * + * THIS SOFTWARE IS PROVIDED BY THE DEVELOPERS ``AS IS'' AND ANY + * EXPRESS OR IMPLIED WARRANTIES, INCLUDING, BUT NOT LIMITED TO, THE IMPLIED + * WARRANTIES OF MERCHANTABILITY AND FITNESS FOR A PARTICULAR PURPOSE ARE + * DISCLAIMED.
