  • Field Details

  • Constructor Details

    • Analyzer

      public Analyzer()

    • Analyzer

      public Analyzer​(ImagePlus imp)
      Constructs a new Analyzer using the specified ImagePlus object and the current measurement options and default results table.

    • Analyzer

      public Analyzer​(ImagePlus imp, ResultsTable rt)
      Construct a new Analyzer using an ImagePlus object and a ResultsTable.

    • Analyzer

      public Analyzer​(ImagePlus imp, int measurements, ResultsTable rt)
      Construct a new Analyzer using an ImagePlus object and private measurement options and a ResultsTable.

  • Method Details

    • 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

    • measure

      public void measure()
      Measures the image or selection and adds the results to the default results table.

    • isRedirectImage

      public static boolean isRedirectImage()
      Returns true if an image is selected in the "Redirect To:" popup menu of the Analyze/Set Measurements dialog box.

    • setRedirectImage

      public static void setRedirectImage​(ImagePlus imp)
      Set the "Redirect To" image. Pass 'null' as the argument to disable redirected sampling.

    • getRedirectImage

      public static ImagePlus getRedirectImage​(ImagePlus cimp)
      Returns the image selected in the "Redirect To:" popup menu of the Analyze/Set Measurements dialog, or null if "None" is selected, the image was not found or the image is not the same size as currentImage.

    • saveResults

      public void saveResults​(ImageStatistics stats, Roi roi)
      Saves the measurements specified in the "Set Measurements" dialog, or by calling setMeasurements(), in the default results table.
