Hello Thomas,
thanks for the fast reply! I tried setting the property but I think I still
miss something. I use the following code to set the Transferfunction:
// set the rendering mode
mitk::RenderingModeProperty::Pointer renderingModeProp =
mitk::RenderingModeProperty::New()
renderingModeProp->SetValue(mitk::RenderingModeProperty::COLORTRANSFERFUNCTION_LEVELWINDOW_COLOR);
node->SetProperty("RenderingMode", renderingModeProp);
// set the transfer function
mitk::TransferFunctionProperty::Pointer transferFuncProp =
mitk::TransferFunctionProperty::New();
mitk::TransferFunction::Pointer transferFunction =
mitk::TransferFunction::New();
transferFunction->AddRGBPoint(1, 1,0,0); // label 1 should be red
transferFunction->AddRGBPoint(2, 0,1,0); // label 2 green
transferFuncProp->SetValue(transferFunction);
node->SetProperty("TransferFunction", transferFuncProp);
multiWidget->RequestUpdate();
thanks,
michael
ps: sorry for spamming you thomas ;)
