Hello, it seems rather simple but i did not manage to manually load a color table in c++.

I would like also if possible to set manually the min and max.

Thanks

Nevermind I found it :

> vtkMRMLMultiVolumeDisplayNode\* mvD = mVolumeNode-\>GetMultiVolumeDisplayNode();  
> mvD-\>AutoWindowLevelOff();  
> mvD-\>SetAndObserveColorNodeID(“vtkMRMLColorTableNodeFileColdToHotRainbow.txt”);  
> mvD-\>SetWindowLevelMinMax(35,50);
