Class LinearStretchEnhancementFilter

java.lang.Object

org.gvsig.fmap.dal.coverage.grid.filter.BaseRasterFilter

org.gvsig.raster.impl.grid.filter.enhancement.LinearStretchEnhancementFilter

All Implemented Interfaces:

java.lang.Cloneable, RasterFilter

Direct Known Subclasses:

LinearStretchEnhancementByteFilter, LinearStretchEnhancementDoubleFilter, LinearStretchEnhancementFloatFilter, LinearStretchEnhancementIntegerFilter, LinearStretchEnhancementShortFilter

public class LinearStretchEnhancementFilter
extends BaseRasterFilter

Clase base para los filtros de realzado lineal. Lee el mínimo y máxmo de la clase Statistic que serán calculados por PercentTailTrimFilter o ComputeMinMaxFilter dependiendo de si está activado el recorte de colas o no. En Statistic también están los segundos valores después del mínimo y máximo que son los que se utilizan con la opción eliminar extremos activada. Estos se usaran en vez del mínimo y máximo cuando la variable removeExtrema esté a true.
