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

doInverseTransform

void doInverseTransform(FHT fht,
                        ImageProcessor ip)

newFHT

FHT newFHT(ImageProcessor ip)

pad

ImageProcessor pad(ImageProcessor ip)

showStatus

void showStatus(java.lang.String msg)

customFilter

void customFilter(FHT fht)

getFilter

ImageProcessor getFilter(int size)

padFilter

ImageProcessor padFilter(ImageProcessor ip,
                         int maxN)
