Interface ShadedRelief

All Known Implementing Classes:
ShadedReliefImpl
public interface ShadedRelief
The ShadedRelief element selects the application of relief shading (or “hill shading”) to an image for a three-dimensional visual effect.

Exact parameters of the shading are system-dependent (for now). If the BrightnessOnly flag is “0” or “false” (false, default), the shading is applied to the layer being rendered as the current RasterSymbolizer. If BrightnessOnly is “1” or “true” (true), the shading is applied to the brightness of the colors in the rendering canvas generated so far by other layers, with the effect of relief-shading these other layers. The default for BrightnessOnly is “0” (false). The ReliefFactor gives the amount of exaggeration to use for the height of the “hills.” A value of around 55 (times) gives reasonable results for Earth-based DEMs. The default value is system-dependent.

  • Method Details

    • isBrightnessOnly

      boolean isBrightnessOnly()
      indicates if brightnessOnly is true or false. Default is false.
      Returns:
      boolean brightnessOn.

    • getReliefFactor

      Expression getReliefFactor()
      The ReliefFactor gives the amount of exaggeration to use for the height of the ?hills.? A value of around 55 (times) gives reasonable results for Earth-based DEMs. The default value is system-dependent.
      Returns:
      an expression which evaluates to a double.

    • accept

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

    • setBrightnessOnly

      void setBrightnessOnly(boolean flag)
      turns brightnessOnly on or off depending on value of flag.
      Parameters:
      flag - boolean

    • setReliefFactor

      void setReliefFactor(Expression reliefFactor)
      The ReliefFactor gives the amount of exaggeration to use for the height of the ?hills.? A value of around 55 (times) gives reasonable results for Earth-based DEMs. The default value is system-dependent.
      Parameters:
      reliefFactor - an expression which evaluates to a double.

    • accept

      void accept(StyleVisitor visitor)
