    public interface ColorMap
    The ColorMap element defines the mapping of palette-type raster colors or fixed- numeric pixel values to colors using an Interpolate or Categorize SE function

    For example, a DEM raster giving elevations in meters above sea level can be translated to a colored image with a ColorMap. The quantity attributes of a color-map are used for translating between numeric matrixes and color rasters and the ColorMap entries should be in order of increasing numeric quantity so that intermediate numeric values can be matched to a color (or be interpolated between two colors). Labels may be used for legends or may be used in the future to match character values. Not all systems can support opacity in colormaps. The default opacity is 1.0 (fully opaque). Defaults for quantity and label are system-dependent.
