Method Summary

boolean	dialogItemChanged(GenericDialog gd, java.awt.AWTEvent e) 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).
void	run(ImageProcessor ip) Filters use this method to process the image.
void	setNPasses(int nPasses) This method is called by ImageJ to inform the plugin-filter about the passes to its run method.
int	setup(java.lang.String arg, ImagePlus imp) This method is called once when the filter is loaded.
int	showDialog(ImagePlus imp, java.lang.String command, PlugInFilterRunner pfr) This method is called after setup(arg, imp) unless the DONE flag has been set.

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

showDialog

public int showDialog(ImagePlus imp,
                      java.lang.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,
                                 java.awt.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
