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.

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. |
boolean |
isBrightnessOnly()
indicates if brightnessOnly is true or false. |
void |
setBrightnessOnly(boolean flag)
turns brightnessOnly on or off depending on value of flag. |
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. |
