Ok
I want to use a binary image (mask) to mask out all data which is outside my
image. In my opinion the easiest way is to draw everything black which is
"zero" (and transparent where it is "one").
I do not understand why (this very simple code) doesn't work (i get something
red, i did not defined any red, arg...):
m_oMaskNode = mitk::DataNode::New();
m_oMaskNode->SetData(m_poMaskImage3D); //binary mitk::Image
mitk::CoreObjectFactory::GetInstance()->SetDefaultProperties(m_oMaskNode);
m_oMaskNode->SetProperty("binary", mitk::BoolProperty::New(false), poRenderer);
m_oMaskNode->SetProperty("visible", mitk::BoolProperty::New(true), poRenderer);
m_oMaskNode->SetProperty("opacity", mitk::FloatProperty::New(1), poRenderer);
m_oMaskNode->SetProperty("use color", mitk::BoolProperty::New(false),
poRenderer);
m_oMaskNode->SetProperty("layer", mitk::IntProperty::New(10000), poRenderer);
mitk::LevelWindowProperty::Pointer oLevWinProp =
mitk::LevelWindowProperty::New();
mitk::LevelWindow oLevWin;
oLevWin.SetRangeMinMax(0,1);
oLevWinProp->SetLevelWindow( oLevWin );
m_oMaskNode->SetProperty( "levelwindow", oLevWinProp, poRenderer);
m_oMaskMapper = mitk::ImageMapper2D::New();
m_oMaskMapper->SetDataNode(m_oMaskNode);
m_oMaskMapper->SetGeometry3D(this->m_Geometry3D);
mitk::LookupTable::Pointer oMitkLut = mitk::LookupTable::New();
vtkLookupTable* poVtkLut = oMitkLut->GetVtkLookupTable();
poVtkLut->SetNumberOfColors(2);
poVtkLut->Build();
poVtkLut->SetTableValue(0, 1.0, 1.0, 1.0, 1.0 ); //black
poVtkLut->SetTableValue(1, 0.0, 0.0, 0.0, 0.0 ); //transparent
mitk::LookupTableProperty::Pointer oMitkLutProp =
mitk::LookupTableProperty::New();
oMitkLutProp->SetLookupTable(oMitkLut);
m_oMaskNode->SetProperty("LookupTable", oMitkLutProp, poRenderer);
m_oMaskMapper->Paint(poRenderer);
