Interface Displacement

All Known Implementing Classes:
DisplacementImpl
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.

  • Method Details

    • getDisplacementX

      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.
      Returns:
      Horizontal offeset

    • getDisplacementY

      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.
      Returns:
      Expression

    • accept

      Object accept(TraversingStyleVisitor visitor, Object extraData)
      calls the visit method of a StyleVisitor
      Parameters:
      visitor - the style visitor

    • setDisplacementX

      void setDisplacementX(Expression x)
      Sets the expression that computes a pixel offset from the geometry point.

    • setDisplacementY

      void setDisplacementY(Expression y)
      Sets the expression that computes a pixel offset from the geometry point.

    • accept

      void accept(StyleVisitor visitor)
