DK11 for Java | tatukgis.jdk.TGIS_GradientMap.RealizeColorMap | Constructors | Methods | Properties

Prepares a colormap as requested.

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

Syntax

// Java
public TGIS_ColorMap[] RealizeColorMap(
  TGIS_ColorMapMode _mode,
  int _subClass,
  bool _reverse
);

// Oxygene
public
  function RealizeColorMap(
    _mode : TGIS_ColorMapMode = TGIS_ColorMapMode.Continuous;
    _subClass : Integer = 0;
    _reverse : Boolean = False
  ) : TGIS_ColorMapArray;

Parameters

Name	Type	Description
_mode	TGIS_ColorMapMode	colormap mode (continuous by default or discrete)
_subClass	int Integer	if available, gets subclass of a ramp with specified, or the possible nearest to specified, number of colors; if 0, gets default colormap (this is the default parameter);
_reverse	bool Boolean	if True, reverses colors from colormap (False is the default parameter);

Result

Type	Description
TGIS_ColorMap[] TGIS_ColorMapArray	Array of a colormap.

Remarks

Mode

Color ramps can be prepared in continuous or discrete mode by setting desired TGIS_ColorMapMode to the _mode parameter.



Continuous mode (default)	Discrete mode

Subclasses

Some ramps, besides the default definition, have versions prepared with a specific number of colors. Using _subclass parameter, you can request a colormap with a defined number of colors, if suchcolormap representation exist.

Three different representations of YellowGreenBlue color ramp.


Color ramp with 3 colors (subclass=3)	Default color ramp definition (subclass=0)	Color ramp with 9 colors (subclass=9)
