TGIS_ColorMapMode enum

DK for Delphi | GisTypesUI.TGIS_ColorMapMode | Enums

Defines colormap mode.

Available also on: .NET | Java | ActiveX | Python.

// Delphi
type
  TGIS_ColorMapMode = (
    Continuous, Discrete
  );

// C++ Builder
enum DECLSPEC_DENUM TGIS_ColorMapMode unsigned short {
  Continuous, Discrete
};

Below are a few examples of how to apply a specified color ramp to a grid layer.

// pseudocode
min_value = grid_layer.MinHeight
max_value = grid_layer.MaxHeight
 
// default representation of 'ElevationDark' color ramp
color_ramp = TGIS_Utils.GisColorRampList.ByName(TGIS_ColorRampNames.ElevationDark)
color_map = color_ramp.RealizeColorMap(TGIS_ColorMapMode.Continuous, 0, false )
grid_layer.GenerateRampEx(min_value, max_value, color_map, nil)
 
// discrete representation of 'Accent' color ramp with maximum number of colors
color_ramp = TGIS_Utils.GisColorRampList.ByName(TGIS_ColorRampNames.Accent)
color_map = color_ramp.RealizeColorMap(TGIS_ColorMapMode.Discrete, -1, false)
grid_layer.GenerateRampEx(min_value, max_value, color_map, nil)
 
// reversed continuous representation of 'Spectral' color ramp, get subclass with 3 colors
color_ramp = TGIS_Utils.GisColorRampList.ByName(TGIS_ColorRampNames.Spectral)
color_map = color_ramp.RealizeColorMap(TGIS_ColorMapMode.Continuous, 3, true)
grid_layer.GenerateRampEx(min_value, max_value, color_map, nil)
