public interface PlugInFilter

ImageJ plugins that process an image should implement this interface. For filters that have a dialog asking for options or parameters as well as for filters that have a progress bar and process stacks the ExtendedPlugInFilter interface is recommended.

Field Summary

static int	CONVERT_TO_FLOAT Set this flag to have the ImageProcessor that is passed to the run() method converted to a FloatProcessor.
static int	DOES_16 Set this flag if the filter handles 16-bit images.
static int	DOES_32 Set this flag if the filter handles float images.
static int	DOES_8C Set this flag if the filter handles 8-bit indexed color images.
static int	DOES_8G Set this flag if the filter handles 8-bit grayscale images.
static int	DOES_ALL Set this flag if the filter handles all types of images.
static int	DOES_RGB Set this flag if the filter handles RGB images.
static int	DOES_STACKS Set this flag if the filter wants its run() method to be called for all the slices in a stack.
static int	DONE Set this flag if the filter does not want its run method called.
static int	FINAL_PROCESSING Set this flag if the setup method of the filter should be called again after the calls to the run(ip) have finished.
static int	KEEP_THRESHOLD Set this flag to keep the invisible binary threshold from being reset.
static int	NO_CHANGES Set this flag if the filter makes no changes to the pixel data and does not require undo.
static int	NO_IMAGE_REQUIRED Set this flag if the filter does not require that an image be open.
static int	NO_UNDO Set this flag if the filter does not require undo.
static int	PARALLELIZE_STACKS Set this flag if the slices of a stack may be processed in parallel threads
static int	ROI_REQUIRED Set this flag if the filter requires an ROI.
static int	SNAPSHOT Set this flag if the filter requires a snapshot (copy of the pixels array).
static int	STACK_REQUIRED Set this flag if the filter requires a stack.
static int	SUPPORTS_MASKING Set this flag if the filter wants ImageJ, for non-rectangular ROIs, to restore that part of the image that's inside the bounding rectangle but outside of the ROI.

Method Summary

void	run(ImageProcessor ip) Filters use this method to process the image.
int	setup(java.lang.String arg, ImagePlus imp) This method is called once when the filter is loaded.

Method Detail

setup

int setup(java.lang.String arg,
          ImagePlus imp)

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.

run

void run(ImageProcessor ip)

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.
