Examples of ChannelSelection

org.geotools.styling.ChannelSelection
The ChannelSelection element specifies the false-color channel selection for a multi-spectral raster source (such as a multi-band satellite-imagery source). It is defined as:
```
 <xs:element name="ChannelSelection"> <xs:complexType> <xs:choice> <xs:sequence> <xs:element ref="sld:RedChannel"/> <xs:element ref="sld:GreenChannel"/> <xs:element ref="sld:BlueChannel"/> </xs:sequence> <xs:element ref="sld:GrayChannel"/> </xs:choice> </xs:complexType> </xs:element> <xs:element name="RedChannel" type="sld:SelectedChannelType"/> <xs:element name="GreenChannel" type="sld:SelectedChannelType"/> <xs:element name="BlueChannel" type="sld:SelectedChannelType"/> <xs:element name="GrayChannel" type="sld:SelectedChannelType"/> 
```
Either a channel may be selected to display in each of red, green, and blue, or a single channel may be selected to display in grayscale. (The spelling ?gray? is used since it seems to be more common on the Web than ?grey? by a ratio of about 3:1.) Contrast enhancement may be applied to each channel in isolation. Channels are identified by a system and data-dependent character identifier. Commonly, channels will be labelled as ?1?, ?2?, etc. @author iant @source $URL$
