From 1a55dd11f1e0c17452c3264ff02496d8ced8a421 Mon Sep 17 00:00:00 2001 From: Teravus Ovares Date: Wed, 21 Jan 2009 11:16:33 +0000 Subject: * More friendly OpenJpeg error handling. * Often times now the only reason OpenJpeg doesn't work is because it requires Glibc 2.4 The error messages reflect that. * In J2kDecoder module, It stops trying to decode modules if it encounters a dllnotfound exception and instead sends a full resolution layer that causes the texture sender to only send the full resolution image. (big decrease in texture download speed, but it's better then nasty repeating error messages) --- .../Agent/TextureSender/J2KDecoderModule.cs | 74 +++++++++++++--------- .../DynamicTexture/DynamicTextureModule.cs | 14 +++- .../Scripting/LoadImageURL/LoadImageURLModule.cs | 12 +++- .../Scripting/VectorRender/VectorRenderModule.cs | 12 +++- .../World/WorldMap/TexturedMapTileRenderer.cs | 29 +++++++-- 5 files changed, 105 insertions(+), 36 deletions(-) (limited to 'OpenSim/Region/Environment') diff --git a/OpenSim/Region/Environment/Modules/Agent/TextureSender/J2KDecoderModule.cs b/OpenSim/Region/Environment/Modules/Agent/TextureSender/J2KDecoderModule.cs index 6b84880..dc46dc6 100644 --- a/OpenSim/Region/Environment/Modules/Agent/TextureSender/J2KDecoderModule.cs +++ b/OpenSim/Region/Environment/Modules/Agent/TextureSender/J2KDecoderModule.cs @@ -49,6 +49,7 @@ namespace OpenSim.Region.Environment.Modules.Agent.TextureSender /// Cached Decoded Layers /// private readonly Dictionary m_cacheddecode = new Dictionary(); + private bool OpenJpegFail = false; /// /// List of client methods to notify of results of decode @@ -147,49 +148,64 @@ namespace OpenSim.Region.Environment.Modules.Agent.TextureSender int DecodeTime = 0; DecodeTime = System.Environment.TickCount; OpenJPEG.J2KLayerInfo[] layers = new OpenJPEG.J2KLayerInfo[0]; // Dummy result for if it fails.
