public interface PolygonSymbolizer
A symbolizer describes how a polygon feature should appear on a map.
The symbolizer describes not just the shape that should appear but also such graphical properties as color and opacity.
A symbolizer is obtained by specifying one of a small number of different types of symbolizer and then supplying parameters to overide its default behaviour.
The details of this object are taken from the OGC Styled-Layer Descriptor Report (OGC 02-070) version 1.0.0.:
<xsd:element name="PolygonSymbolizer" substitutionGroup="sld:Symbolizer">
<xsd:annotation>
<xsd:documentation>
A "PolygonSymbolizer" specifies the rendering of a polygon or
area geometry, including its interior fill and border stroke.

<xsd:extension base="sld:SymbolizerType">

Renderers can use this information when displaying styled features, though it must be remembered that not all renderers will be able to fully represent strokes as set out by this interface. For example, opacity may not be supported.

Method Summary | |
---|---|
Displacement |
getDisplacement()
Displacement from the original geometry in pixels. |
Fill |
getFill()
Provides the graphical-symbolization parameter to use to fill the area of the geometry. |
Stroke |
getStroke()
Provides the graphical-symbolization parameter to use for the outline of the Polygon. |
void |
setDisplacement(Displacement displacement)
Provide x / y offset in pixels used to crate shadows. |
void |
setFill(Fill fill)
Provides the graphical-symbolization parameter to use to fill the area of the geometry. |
void |
setPerpendicularOffset(Expression offset)
PerpendicularOffset works as defined for LineSymbolizer, allowing to draw polygons smaller or larger than their actual geometry. |
void |
setStroke(Stroke stroke)
Provides the graphical-symbolization parameter to use for the outline of the Polygon. |
