Class ImageJ

  • All Implemented Interfaces:
    java.awt.event.ActionListener, java.awt.event.ItemListener, java.awt.event.KeyListener, java.awt.event.MouseListener, java.awt.event.WindowListener, java.awt.image.ImageObserver, java.awt.MenuContainer, java.io.Serializable, java.lang.Runnable, java.util.EventListener, javax.accessibility.Accessible
    public class ImageJ
extends java.awt.Frame
implements java.awt.event.ActionListener, java.awt.event.MouseListener, java.awt.event.KeyListener, java.awt.event.WindowListener, java.awt.event.ItemListener, java.lang.Runnable
    This frame is the main ImageJ class.

    ImageJ is a work of the United States Government. It is in the public domain and open source. There is no copyright. You are free to do anything you want with this source but I like to get credit for my work and I would like you to offer your changes to me so I can possibly add them to the "official" version. 

    The following command line options are recognized by ImageJ:

  "file-name"
     Opens a file
     Example 1: blobs.tif
     Example 2: /Users/wayne/images/blobs.tif
     Example 3: e81*.tif

  -macro path [arg]
     Runs a macro or script (JavaScript, BeanShell or Python), passing an
     optional string argument, which the macro or script can be retrieve
     using the getArgument() function. The macro or script is assumed to 
     be in the ImageJ/macros folder if 'path' is not a full directory path.
     Example 1: -macro analyze.ijm
     Example 2: -macro script.js /Users/wayne/images/stack1
     Example 2: -macro script.py '1.2 2.4 3.8'

  -batch path [arg]
    Runs a macro or script (JavaScript, BeanShell or Python) in
    batch (no GUI) mode, passing an optional argument.
    ImageJ exits when the macro finishes.

  -eval "macro code"
     Evaluates macro code
     Example 1: -eval "print('Hello, world');"
     Example 2: -eval "return getVersion();"

  -run command
     Runs an ImageJ menu command
     Example: -run "About ImageJ..."
     
  -ijpath path
     Specifies the path to the directory containing the plugins directory
     Example: -ijpath /Applications/ImageJ

  -port
     Specifies the port ImageJ uses to determine if another instance is running
     Example 1: -port1 (use default port address + 1)
     Example 2: -port2 (use default port address + 2)
     Example 3: -port0 (don't check for another instance)

  -debug
     Runs ImageJ in debug mode
