Interface Interpolate

All Superinterfaces:
Expression, Function

public interface Interpolate extends Function
Interpolation: Transformation of continuous values by a function defined on a number of nodes. This is used to adjust the value distribution of an attribute to the desired distribution of a continuous symbolization control variable (like size, width, color, etc).

In case the Categorize (or Interpolate) function is used inside a RasterSymbolizer as a ColorMap, the LookupValue is set to the fixed value “Rasterdata”.
