Method Detail

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

run

public static Roi run(ImagePlus imp)

Returns a selection created from the thresholded pixels in the specified image, or null if there are no thresholded pixels.

convert

public Roi convert(ImageProcessor ip)

Returns a selection created from the thresholded pixels in the specified image, or null if there are no thresholded pixels.

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

showStatus

public void showStatus(boolean showStatus)

Determines whether to show status messages and a progress bar
