Class Overview

Specifies the processing to be done to the image service. There are different kinds of Raster Functions. Here is an example of how to construct the Shaded Relief rendering rule.

Java usage: 


 	String argument = " {\"Azimuth\" : 215.0,\"Altitude\" : 60.0,\"ZFactor\" : 5,\"Colormap\" : [[0, 1, 2, 3],  [2, 45, 52, 13]]}";					
	RasterFunction renderingRule = new RasterFunction();				
	renderingRule.setFunctionName("ShadedRelief");
	renderingRule.setArguments(argument);
	renderingRule.setVariableName("Raster");
	imageServiceLayer.setRenderingRule(renderingRule);
	imageServiceLayer.refresh();

Returns
  • Returns the variableName.

public int hashCode ()

public void setArguments (String arguments)

Sets the input arguments to the raster function. For example, clipping geometry for the ClipFunction.

Parameters
arguments The arguments to set, which is a Json string representing the argument object.

public void setArgumentsAsMap (Map<String, Object> mapArguments)

Sets the input arguments to the raster function. For example, clipping geometry for the ClipFunction.

public void setFunctionName (String functionName)

Sets the functionName of the RasterFunction.

Parameters
functionName The functionName to set.

public void setVariableName (String variableName)

Sets the variableName of the RasterFunction.

Parameters
variableName The variableName to set.

public String toJson ()
