Interface Displacement


  • @XmlElement("Displacement")
    public interface Displacement
    The Displacement gives the X and Y displacements from the original geometry. This element may be used to avoid over-plotting of multiple PolygonSymbolizers for one geometry or supplying "shadows" of polygon gemeotries. The displacements are in units of pixels above and to the right of the point. The default displacement is X=0, Y=0.
    Since:
    GeoAPI 2.2

      • getDisplacementX

        @XmlElement("DisplacementX")
        Expression getDisplacementX()
        Returns an expression that computes a pixel offset from the geometry point. This offset point is where the text's anchor point gets located. If this expression is null, the default offset of zero is used.
      • getDisplacementY

        @XmlElement("DisplacementY")
        Expression getDisplacementY()
        Returns an expression that computes a pixel offset from the geometry point. This offset point is where the text's anchor point gets located. If this expression is null, the default offset of zero is used.
