# cee::vis::ColorTableFactory

class `ColorTableFactory`

  Factory functions for creating color tables based on a predefined number of color schemes.

  These color tables can then be used to configure scalar mappers, which will again be used to setup a color legend (e.g. OverlayColorLegendContinuousDomain).

  Public Types

  enum `ColorTable`

    The predefined color schemes supported by the color table factory.

    Values:

    enumerator `NORMAL`

      The standard color map for scalar mapping in EnvisionDesktop. Following the color spectra, but starting on blue and ending on red.

    enumerator `BLACK_WHITE`

      Black to while color map.

    enumerator `BLUE_RED`

      Blue to red color map.

    enumerator `BLUE_GREEN`

      Blue to green color map.

    enumerator `YELLOW_RED`

      Yellow to red color map.

    enumerator `GREEN_YELLOW_RED`

      A map from Green through yellow ending up in red.

    enumerator `RED_YELLOW`

      A red to yellow color map.

    enumerator `THERMAL_1`

      A map suitable for thermal scalars.

    enumerator `THERMAL_2`

      A map suitable for thermal scalars.

    enumerator `THERMAL_3`

      A map suitable for thermal scalars.

    enumerator `METAL_CASTING`

      A map suitable for metal casting.

    enumerator `VIRIDIS`

      Purple to yellow color map.

    enumerator `TURBO`

      A color map that goes from blue to green to red.

    enumerator `COOL_TO_WARM`

      A color map that goes from blue to white to red.

  Public Static Functions

  static std::vector<Color3f> `colorTableArray`(ColorTable colorTable, size_t colorCount)

    Returns an array of colors created from the given color scheme.

    The returned array will have colorCount number of values

  static std::vector<Color3f> `interpolateColorArray`(const std::vector<Color3f> &colorArray, size_t targetColorCount)

    Interpolates a graded color table with the given number of colors (targetColorCount) based on the input colors (colorArray).

    This is useful for creating gradient/continuous style color maps based on two or more colors.
