Hi all,
I want to use the LabeledImageLookupTable class to show a labeled
image in different colors, but I am not able to transform it into a
LookupTableProperty.
The problem is that LookupTableProperty needs a LookupTable as
initialization. I have tried to dynamic_cast my labeledImageLUT to
LookupTable like that:
// set colors for the segments
mitk::LabeledImageLookupTable* lut = mitk::LabeledImageLookupTable::New();
std::cout << "LUT created" << std::endl;
lut->SetColorForLabel(1, 1.0, 0.0, 0.0, 1.0 );
lut->SetColorForLabel(2, 0.0, 1.0, 0.0, 1.0 );
lut->SetColorForLabel(3, 0.0, 0.0, 1.0, 1.0 );
lut->SetColorForLabel(4, 0.7, 0.7, 1.0, 1.0 );
std::cout << "Colors set" << std::endl;
for (int i=5;i<256;i++)
{
lut->SetColorForLabel(i, 1.0, 0.5, 0.5, 1.0);
std::cout << i << std::endl;
}
std::cout << "Creating LUTProperty" << std::endl;
mitk::LookupTableProperty* lutProp =
mitk::LookupTableProperty::New(dynamic_cast<mitk::LookupTable*>(lut));
newNode->SetProperty ( "LookupTable", lutProp );
But I get an runtime exception at the line:
lut->SetColorForLabel(1, 1.0, 0.0, 0.0, 1.0 );
I guess it has to do with the fact that "lut" is not created as
"Pointer" but with "*".
Could somebody please suggest how I can use the
LabeledImageLookupTable correctly?
Thanks for your help in advance.
Best regards,
Xabier
