Detailed Description

A lookup table for 2D mapping of labeled images. The lookup table supports images with up to 256 unsigned labels. Negative labels are not supported. Please use the level/window settings as given by the GetLevelWindow() method to make sure, that the colors are rendered correctly. The colors are initialized with random colors as default. As background the label 0 is assumed. The color for the background is set to fully transparent as default.

Member Typedef Documentation

◆ LabelType

The data type for a label. Currently only images with labels in the range [0,255] are supported.

Constructor & Destructor Documentation

◆ LabeledImageLookupTable() [1/2]

mitk::LabeledImageLookupTable::LabeledImageLookupTable ( )

Default constructor. Protected to prevent "normal" creation

◆ LabeledImageLookupTable() [2/2]

mitk::LabeledImageLookupTable::LabeledImageLookupTable ( const LabeledImageLookupTable other)

◆ ~LabeledImageLookupTable()

mitk::LabeledImageLookupTable::~LabeledImageLookupTable ( )

Virtual destructor

Member Function Documentation

◆ Clone()

Pointer mitk::LabeledImageLookupTable::Clone ( ) const

◆ GenerateRandomColor()

virtual void mitk::LabeledImageLookupTable::GenerateRandomColor ( double &  r,
double &  g,
double &  b 

Generates a random rgb color value. Values for rgb are in the range [0,1]

◆ GenerateRandomNumber()

virtual double mitk::LabeledImageLookupTable::GenerateRandomNumber ( )

Generates a radnom number drawn from a uniform distribution in the range [0,1].

◆ GetColorForLabel()

virtual double* mitk::LabeledImageLookupTable::GetColorForLabel ( const LabelType label)

Determines the color which will be used for coloring a given label.

labelthe label for which the color should be returned
an rgba array containing the color information for the given label. Color components are expressed as [0,1] double values.

◆ GetLevelWindow()

mitk::LevelWindow mitk::LabeledImageLookupTable::GetLevelWindow ( )

Provides access to level window settings, which should be used in combination with the LUTs generated by this filter (at lease for 2D visualization. If you use other level/window settings, it is not guaranteed, that scalar values are mapped to the correct colors.

Definition at line 80 of file mitkLabeledImageLookupTable.h.

◆ mitkClassMacro()

mitk::LabeledImageLookupTable::mitkClassMacro ( LabeledImageLookupTable  ,

Standard mitk typedefs are generated by the mitkClassMacro

◆ New()

static Pointer mitk::LabeledImageLookupTable::New ( )

Make this object constructable by the ::New() Method.

◆ operator=()

LabeledImageLookupTable& mitk::LabeledImageLookupTable::operator= ( const LookupTable LookupTable)

implementation necessary because operator made private in itk::Object

Reimplemented from mitk::LookupTable.

◆ SetColorForLabel()

virtual void mitk::LabeledImageLookupTable::SetColorForLabel ( const LabelType label,
const double &  r,
const double &  g,
const double &  b,
const double  a = 1.0 

Sets the color for a given label

labelThe pixel value used as a label in the image
rThe red component of the rgba color value. Values sould be given in the range [0,1]
gThe green component of the rgba color value. Values sould be given in the range [0,1]
bThe blue component of the rgba color value. Values sould be given in the range [0,1]
aThe alpha component of the rgba color value. Values sould be given in the range [0,1]. Default is 1.
