... This method is called once when the filter is loaded. ... This method should return a flag word that specifies the filters capabilities. ... With CONVERT_TO_FLOAT, the filter is called with the image data converted to a FloatProcessor (3 times per image for RGB images). ImageJ will lock the image before calling this method and unlock it when the filter is finished. For PlugInFilters specifying the NO_IMAGE_REQUIRED flag and not the DONE flag, run(ip) is called once with the argument null . ...

... GUIDE'' (Graphical User Interface for a Data Environment) is an interactive IDL widget-based package that enables users to retrieve selected sets of satellite instrument data and perform various types of graphical analyses on them, without writing a specialized program. GUIDE simplifies the task of laying out multiple plots on a page by (1) using a page-editor to define and laying out multiple ``panels'' which contain the ``plot objects'', and (2) integrating data retrieval functions. ...
