Examples of javax.media.jai.RasterAccessor.needsClamping()

javax.media.jai.RasterAccessor.needsClamping()
Indicates if the RasterAccessor has a larger dynamic range than the underlying Raster. Except in special cases, where the op knows something special, this call will determine whether or not clampDataArrays() needs to be called.
