[SOLVED] MET heightmap pixel format

Hi. I want to do with MOGRE Editable Terrain Manager something like this:
...
Mogre.Image image = new Mogre.Image();
image.Load("..\\media\\terrain.png", "General");
splattingManager.LoadMapFromImage(0, image);
...


But on the "LoadMapFromImage" program crashes and in the log is:
...
OGRE EXCEPTION(2:InvalidParametersException): Given image is of invalid pixel format. in CoverageMap::loadFromImage at .\src\ETSplattingManager.cpp (line 178)
...


Can you tell me which pixel format I need and which program should I use to convert to it?

I found the problem. Heightmap must be loaded using TerrainInfo class.

...
Mogre.Image image = new Mogre.Image();
image.Load("..\\media\\terrain.png", "General");

TerrainInfo terrainInfo = new TerrainInfo();
TerrainInfo.LoadHeightmapFromImage(terrainInfo, image);

mTerrainManager.CreateTerrain(terrainInfo);
