Interface ShadedRelief

All Superinterfaces:

ShadedRelief

public interface ShadedRelief
extends ShadedRelief

The ShadedRelief element selects the application of relief shading (or ?hill shading?) to an image for a three-dimensional visual effect. It is defined as:

 <xs:element name="ShadedRelief">
   <xs:complexType>
     <xs:sequence>
       <xs:element ref="sld:BrightnessOnly" minOccurs="0"/>
       <xs:element ref="sld:ReliefFactor" minOccurs="0"/>
     </xs:sequence>
   </xs:complexType>
 </xs:element>
 <xs:element name="BrightnessOnly" type="xs:boolean"/>
 <xs:element name="ReliefFactor" type="xs:double"/>
 

Exact parameters of the shading are system-dependent (for now). If the BrightnessOnly flag is ?0? (false, default), the shading is applied to the layer being rendered as the current RasterSymbol. If BrightnessOnly is ?1? (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 Detail

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)
