Interface Halo

All Known Implementing Classes:
HaloImpl

public interface Halo

A Halo fills an extended area outside the glyphs of a rendered textlabel to make it easier to read over a background.

The details of this object are taken from the OGC Styled-Layer Descriptor Report (OGC 02-070) version 1.0.0.:


 <xsd:element name="Halo">
   <xsd:annotation>
     <xsd:documentation>
      A "Halo" fills an extended area outside the glyphs of a rendered
       text label to make the label easier to read over a background.
     </xsd:documentation>
   </xsd:annotation>
   <xsd:complexType>
     <xsd:sequence>
       <xsd:element ref="sld:Radius" minOccurs="0"/>
       <xsd:element ref="sld:Fill" minOccurs="0"/>
     </xsd:sequence>
   </xsd:complexType>
 </xsd:element>
 

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.
