Class PointSymbolizer

java.lang.Object
  extended by org.deegree.graphics.sld.AbstractSymbolizer
      extended by org.deegree.graphics.sld.PointSymbolizer
All Implemented Interfaces:
Marshallable, Symbolizer

public class PointSymbolizer
extends AbstractSymbolizer
implements Marshallable

Used to render a "graphic" at a point. If a line-string or polygon geometry is used with this symbol, then the semantic is to use the centroid of the geometry, or any similar representative point. The meaning of the contained elements are discussed with the element definitions below. If the Geometry element is omitted, then the "default" geometry for the feature type is used. (Many feature types will have only one geometry attribute.) If the Graphic element is omitted, then nothing will be plotted.

Method Detail

getGraphic

public Graphic getGraphic()
A Graphic is a "graphic symbol" with an inherent shape, color, and size. Graphics can either be referenced from an external URL in a common format (such as GIF or SVG) or may be derived from a Mark. Multiple external URLs may be referenced with the semantic that they all provide the same graphic in different formats. The "hot spot" to use for rendering at a point or the start and finish handle points to use for rendering a graphic along a line must either be inherent in the external format or are system- dependent. The default size of an image format (such as GIF) is the inherent size of the image. The default size of a format without an inherent size is 16 pixels in height and the corresponding aspect in width. If a size is specified, the height of the graphic will be scaled to that size and the corresponding aspect will be used for the width. The default if neither an ExternalURL nor a Mark is specified is to use the default Mark with a size of 6 pixels. The size is in pixels and the rotation is in degrees clockwise, with 0 (default) meaning no rotation. In the case that a Graphic is derived from a font-glyph Mark, the Size specified here will be used for the final rendering. Allowed CssParameters are "opacity", "size", and "rotation".

Returns:
the graphic of the point

setGraphic

public void setGraphic(Graphic graphic)
sets the

Parameters:
graphic - the graphic of the point

exportAsXML

public java.lang.String exportAsXML()
exports the content of the PointSymbolizer as XML formated String

Specified by:
exportAsXML in interface Marshallable
Returns:
xml representation of the PointSymbolizer
