Module Description

The Color Module manages color look up tables.

Look-up Tables (LUTs) are used by mappers to translate between an integer and a color value for display of models and volumes.

Usage

Use Cases, Examples

This module is especially appropriate for these use cases:

  • Use Case 1: change the color mapping of volumes
    • In the Volumes module, Display tab, you can select a new color table for grey scale or label map volumes.
  • Use Case 2: change model scalar overlays
    • In the Models module, Display tab, you can select a new color table to map scalar overlays associated with the model.
  • Use Case 3: create new color tables
    • Either copy an existing color node or create a new one in the Colors module, Edit tab.
    • You can then save it with the scene so it gets loaded again whenever that scene is opened. or copy it into a special directory where it will be loaded whenever Slicer is run.

Examples of the module in use:

  • Create a custom color file for a brain segmentation

Tutorials

Links to tutorials explaining how to use this module:

Quick Tour of Features and Use

You can specify a directory from which to read color files using the View -> Application Settings window, Module Settings frame. Click on the Add a preset button to add one or more new user color file paths. The directory will be searched for color files with names ending in .txt or .ctbl and loaded on start up. You have to restart Slicer to load the new files after setting the paths the first time.

SlicerModuleSettingsColor-3.6.jpg

You can deactivate paths or delete them as well using this interface.

Color files have one color per line:

label name R G B A

label is an integer, name a string, and there are four integers for RGBA in the inclusive range 0-255. The A stands for opacity, use 255 for opaque.

In a the binary directory of Slicer3, the default color files live in share/Slicer3/SlicerBaseLogic/Resources/ColorFiles. In the source directory, they live in Base/Logic/Resources/ColorFiles.

Display panel

Color Display

This is a stand alone widget that can be popped up by other modules, for example the Editor. Here it lets you inspect the values of the selected colour look up table.

Slicer supports three kinds of tables:

  1. Continuous scales, like the greyscale table.
  2. Parametric tables, defined by an equation, such as the FMRIPA table.
  3. Discrete tables, such as those read in from a file.
  • Color Select: Choose from a drop down list of color nodes.

SlicerColorNodeCategories-3.6.jpg

The colors are divided up into categories. These descriptions can be found in the Help and Acknowlegements tab at the top of the module's GUI.

  • Auto Loaded User Color Files:
    • Files loaded from the user specified color paths in the Module Settings, can be saved with the scene
  • File
    • If you load a color file from File -> Add Data, it will appear here
  • User Generated
    • If you create a new color node in the Editor panel, it will appear here
  • Node Type: a label updated to give the type of the node currently being displayed
  • Total Number of Colours in Table: a label updated to display the number of entries in the color look up table.
  • Selected Color Label: used especially in the Editor module, draw with the colour last clicked upon in the table.
  • List box: The contents of the colour table, the entry is the integer label value, the name will show up in the label map layer of th 22d slice windows when you mouse over voxels with the corresponding value, the Color column shows how the voxel will be rendered.
  • Show Only Named Colors: when this box is checked, the list box will only be populated by named colours. Some colour tables can have memtpy entries that have no name and default to black, this option lets you hide or show them.
  • Lookup Table Range Min Max': Changes the range of values displayed, doesn't change the number of values in the table.

Scalar Bar

Scalar Bar

This panel lets you add a scalar bar widget to the 3D view showing the mapping between the integers and the colors in the color node.

  • Display Scalar Bar: click on this to add a scalar bar to the scene, showing the currently selected color node in the Color Select drop down menu
  • Title: set the title of the scalar bar, mm is used by default
  • Title Properties: set the text display properties of the title text
    • Color
    • Font
    • Style
    • Opacity
  • Label Format: The label format entry box uses the standard C++ string format. Format documentation
  • Label Text Properties: Define how the labels are displayed along the length of the scalar bar widget.

  • Maximum number of Colors: set the maximum number of scalar bar segments to show
  • Number of labels: set the number of labels to show.

Edit panel

This panel lets users create a new colour look up table file, or edit an existing one.

Slicer-ColorGUI-Edit-3.6.jpg

Use the Edit frame to create a new color table, and save it to the mrml scene.

To create a new color node:

First, give your new color table a name in the Name entry.

Then fill in the Number of Colors. The list box will be populated with the corresponding number of entries. You can reset this to a larger number w/o losing your current settings. Set it to 0 to clear out the list box.

Then click on Generate to populate a new node from the GUI contents. The color node is now available to use in the Volumes or Edit or Save modules. If you've set up user defined color file paths, the node will be set up automatically to save in the first of them.

To edit an existing color node, click on Select a Color Table to Copy. Pick a node from the drop down list, then click on the Copy Node button, it will fill in the edit box with those values. Make any changes you want, then click on the Generate a New Color Node button. At that point, the new node will show up in the File -> Save Data widget.

Development

Notes from the Developer(s)

A wiki page on LUTs and Ontologies where you can generate a Slicer Color file from a wiki page table.

To install a new defaul color file, commit it to the source code repository in Base/Logic/Resources/ColorFiles. The Slicer3/Base/Logic/CMakeLists.txt will automatically detect and install all *.txt files to the appropriate binary directory.

Dependencies
