Description copied from class: AbstractSLDSymbolizer

This method must be implemented by any symbolizer classes extending this class. New subclasses should use the xPath field to parse the symbolizerNode field, which will contain the symbolizer node of the SLD XML document on execution. The SLD layer name is also provided in the layerName field. The resulting image layer should be returned. New symbolizers must also be registered using the registerSymbolizer method of the StyleSLDParser class at runtime, either in the static initializer of that class or elsewhere before the createImage method of StyleSLDParser is executed.

Specified by:

parseSymbolizer in class AbstractSLDSymbolizer

Returns:

ImageLayer

Throws:

XPathExpressionException

NumberFormatException

SLDException
