Examples of org.geotools.process.RenderingProcess

org.geotools.process.RenderingProcess
An interface to be implemented by processes meant to be integrated as feature collection/grid coverage transformations in a rendering chain.
The method provide information about how the data is altered so that the renderer can query the appropriate part of the input data that will feed the process
