Thanks very much for the hint from Dr. Wegner, and the mitkSeedsInteractor
is indeed what I need.
Now I have a new problem. I am trying to set up a lookuptable for the seed
image so that it can be better visualized.
But somehow my lookuptable SetProperty command has no effect at all, and the
value is always "n/a" as shown in the "Properties" window.
My code is as follows:
m_SeedImageNode = mitk::DataTreeNode::New();
m_SeedImageNode->GetPropertyList()->SetProperty("name",
mitk::StringProperty::New("Seed Image"));
m_SeedImageNode->SetData( m_SeedImage );
m_SeedImageNode->SetProperty("layer", mitk::IntProperty::New(1));
m_SeedImageNode->SetProperty("opacity", mitk::FloatProperty::New(0.5));
mitk::LabeledImageLookupTable::Pointer lut =
mitk::LabeledImageLookupTable::New();
for ( unsigned char i = 0; i < 253; i++ )
{
lut->SetColorForLabel( i, 0.0, 0.0, 0.0, 0.0 );
}
lut->SetColorForLabel(254, 0.0, 1.0, 0.0, 1.0 );
lut->SetColorForLabel(255, 0.7, 0.7, 1.0, 1.0 );
mitk::LookupTableProperty::Pointer lutProp =
mitk::LookupTableProperty::New( lut.GetPointer() );
m_SeedImageNode->SetProperty ( "LookupTable", lutProp );
Could someone pls tell me what's wrong with above code?
Or is there a requirement that the "m_SeedImage" must be of unsigned char
type for the lookuptable to work?
Thanks in advance!
Sincerely,
Xiao
