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

enlargeCanvas

void enlargeCanvas()

drawGridLines

void drawGridLines(int lines)

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(ij.gui.GenericDialog gd,
                                 java.awt.AWTEvent e)

Specified by:

dialogItemChanged in interface ij.gui.DialogListener

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
