Method Detail

• setup

  public int setup​(String arg,
                   ImagePlus imp)

  Description copied from interface: PlugInFilter
  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 PlugInFilter.FINAL_PROCESSING flag, the setup method will be called again, this time with arg = "final" after all other processing is done.

  Specified by:

  setup in interface PlugInFilter

• run

  public void run​(ImageProcessor ip)

  Description copied from interface: PlugInFilter
  Filters use this method to process the image. If the PlugInFilter.DOES_STACKS flag was set, it is called for each slice in a stack. With PlugInFilter.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 PlugInFilter.NO_IMAGE_REQUIRED flag and not the PlugInFilter.DONE flag, run(ip) is called once with the argument null.

  Specified by:

  run in interface PlugInFilter

• showDialog

  public int showDialog​(ImagePlus imp,
                        String command,
                        PlugInFilterRunner pfr)

  Description copied from interface: ExtendedPlugInFilter
  This method is called after setup(arg, imp) unless the DONE flag has been set.

  Specified by:

  showDialog in interface ExtendedPlugInFilter

  Parameters:

  imp - The active image already passed in the setup(arg, imp) call. It will be null, however, if the NO_IMAGE_REQUIRED flag has been set.

  command - The command that has led to the invocation of the plugin-filter. Useful as a title for the dialog.

  pfr - The PlugInFilterRunner calling this plugin-filter. It can be passed to a GenericDialog by addPreviewCheckbox to enable preview by calling the run(ip) method of this plugin-filter. pfr can be also used later for calling back the PlugInFilterRunner, e.g., to obtain the slice number currently processed by run(ip).

  Returns:

  The method should return a combination (bitwise OR) of the flags specified in interfaces PlugInFilter and ExtendedPlugInFilter.

• dialogItemChanged

  public boolean dialogItemChanged​(GenericDialog gd,
                                   AWTEvent e)

  Description copied from interface: DialogListener
  This method is invoked by a Generic Dialog if any of the inputs have changed (CANCEL does not trigger it; OK and running the dialog from a macro only trigger the first DialogListener added to a GenericDialog).

  Specified by:

  dialogItemChanged in interface DialogListener

  Parameters:

  gd - A reference to the GenericDialog.

  e - The event that has been generated by the user action in the dialog. Note that e is null if the dialogItemChanged method is called after the user has pressed the OK button or if the GenericDialog has read its parameters from a macro.

  Returns:

  Should be true if the dialog input is valid. False disables the OK button and preview (if any).

• setNPasses

  public void setNPasses​(int nPasses)

  Description copied from interface: ExtendedPlugInFilter
  This method is called by ImageJ to inform the plugin-filter about the passes to its run method. During preview, the number of passes is one (or 3 for RGB images, if CONVERT_TO_FLOAT has been specified). When processing a stack, it is the number of slices to be processed (minus one, if one slice has been processed for preview before), and again, 3 times that number for RGB images processed with CONVERT_TO_FLOAT.

  Specified by:

  setNPasses in interface ExtendedPlugInFilter
