public interface PlugInFilter

ImageJ plugins that process an image should implement this interface. For filters that have a dialog asking for options or parameters as well as for filters that have a progress bar and process stacks the ExtendedPlugInFilter interface is recommended.

Method Details
- setup
  
  int setup(String arg, ImagePlus imp)
  
  This method is called once when the filter is loaded. 'arg', which may be blank, is the argument specified for this plugin in IJ_Props.txt or in the plugins.config file of a jar archive containing the plugin. 'imp' is the currently active image. This method should return a flag word that specifies the filters capabilities.
  For Plugin-filters specifying the FINAL_PROCESSING flag, the setup method will be called again, this time with arg = "final" after all other processing is done.
- run
  
  void run(ImageProcessor ip)
  
  Filters use this method to process the image. If the DOES_STACKS flag was set, it is called for each slice in a stack. 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.
