Interface Fill

All Superinterfaces:

Drawing

All Known Implementing Classes:

Fill_Impl

public interface Fill

extends Drawing

A Fill allows area geometries to be filled. There are two types of fills: solid-color and repeated GraphicFill. In general, if a Fill element is omitted in its containing element, no fill will be rendered. The default is a solid 50%-gray (color "#808080") opaque fill.

Method Detail

getFill

public java.awt.Color getFill(Feature feature)
                       throws FilterEvaluationException

Returns the (evaluated) value of the fill's CssParameter 'fill'.

Parameters:

feature - specifies the Feature to be used for evaluation of the underlying 'sld:ParameterValueType'

Returns:

the (evaluated) value of the parameter

Throws:

FilterEvaluationException - if the evaluation fails or the value is invalid

setFill

public void setFill(java.awt.Color color)

sets the value of the fill's CssParameter 'fill' as a simple color

Parameters:

color - color to be set

getOpacity

public double getOpacity(Feature feature)
                  throws FilterEvaluationException

Returns the (evaluated) value of the fill's CssParameter 'fill-opacity'.

Parameters:

feature - specifies the Feature to be used for evaluation of the underlying 'sld:ParameterValueType'

Returns:

the (evaluated) value of the parameter

Throws:

FilterEvaluationException - if the evaluation fails or the value is invalid

setOpacity

public void setOpacity(double opacity)

sets the value of the opacity's CssParameter 'opacity' as a value. Valid values ranges from 0 .. 1. If a value < 0 is passed it will be set too 0. If a value > 1 is passed it will be set too 1.

Parameters:

opacity - opacity to be set
