- - ### Constructor Detail

    - #### ColorTable

          public ColorTable​(int ePaletteInterpretation)

      Construct a new color table.

    - #### ColorTable

          public ColorTable()

      Construct a new color table.

      Same as below with ePaletteInterpretation == gdalconst.GPI_RGB

      See Also:
        `ColorTable(int ePaletteInterpretation)`

  - ### Method Detail

    - #### delete

          public void delete()

    - #### clone

          public java.lang.Object clone()

      Make a copy of a color table.

    - #### getIndexColorModel

          public java.awt.image.IndexColorModel getIndexColorModel​(int bits)

    - #### Clone

          public ColorTable Clone()

      Make a copy of a color table.

    - #### GetPaletteInterpretation

          public int GetPaletteInterpretation()

      Fetch palette interpretation.

      The returned value is used to interpret the values in the GDALColorEntry.

      Returns:
        palette interpretation enumeration value, usually gdalconst.GPI_RGB.

    - #### GetCount

          public int GetCount()

      Get number of color entries in table.
      Returns:
        the number of color entries.

    - #### GetColorEntry

          public java.awt.Color GetColorEntry​(int entry)

      Fetch a color entry from table.
      Parameters:
        `entry` - entry offset from zero to GetCount()-1.
      Returns:
        color entry, or null if index is out of range.

    - #### SetColorEntry

          public void SetColorEntry​(int entry,
                                    java.awt.Color centry)

      Set entry in color table.

      The passed in entry must match the color interpretation of the table to which it is being assigned.

      The table is grown as needed to hold the supplied offset.

      Parameters:
        `entry` - entry offset from zero to GetCount()-1.
        `centry` - value to assign to table.

    - #### CreateColorRamp

          public void CreateColorRamp​(int nStartIndex,
                                      java.awt.Color startcolor,
                                      int nEndIndex,
                                      java.awt.Color endcolor)

      Create color ramp.

      Automatically creates a color ramp from one color entry to another. It can be called several times to create multiples ramps in the same color table.

      Parameters:
        `nStartIndex` - index to start the ramp on the color table [0..255]
        `startcolor` - a color value to start the ramp
        `nEndIndex` - index to end the ramp on the color table [0..255]
        `endcolor` - a color value to end the ramp
