Field Detail

darkBlue

public static java.awt.Color darkBlue

markWidth

public static int markWidth

precision

public static int precision

Constructor Detail

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,
                int measurements,
                ResultsTable rt)

Construct a new Analyzer using an ImagePlus object and private measurement options and results table.

Method Detail

setup

public int setup(java.lang.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 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 SUPPORTS_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.

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 currentImage)

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.

displayResults

public void displayResults()

Writes the last row in the system results table to the Results window.

updateHeadings

public void updateHeadings()

Redisplays the results table.

n

public java.lang.String n(double n)

Converts a number to a formatted string with a tab at the end.

public void summarize()

getCounter

public static int getCounter()

Returns the current measurement count.

resetCounter
