Edit: Similar to word processor functionality (Copy, Paste, etc.).produced by print statements) and any errors encountered during script execution. Multiple scripts can be open at the same time and will show up as separate tabs. To start the script editor in Fiji go to menu File > New > Script…. The download section contains scripts written in the Jython and BeanShell languages. Step-by-step instructions in this tutorial are provided for developing scripts in Jython. BeanShell: Syntax similar to Java, versatileįiji provides a richer programming environment than ImageJ and it is recommended to use Fiji instead of ImageJ for any script development.Jython: Python syntax with a few limitations, easy to learn, very versatile.ImageJ macro language: simple, slow, not very versatile.The API is well documented on these public sites:įiji provides convenient programming wrappers for these Java classes so you can write your scripts in: The application programming interface (API) defines the various Java packages, classes, methods, and constants that a programmer can use for development of custom Fiji & ImageJ scripts. The Application Programming Interface (API)įiji and ImageJ are written in Java.

Windows 7 & 10: The Fiji application should be installed in the the user’s home directory rather than the default C:\Program Files directory.MacOS X: The Fiji application should be installed in the the user’s home directory rather than the default Applications folder.
It is available for Mac OSX, Windows, and Linux platforms.
Intro & Fiji Programming Tools Installationįiji is a stand-alone application that can be downloaded from theįiji website. Example scripts are provided for the Jython and BeanShell languages. Step-by-step instructions are provided for developing scripts in Jython, an implementation of the popular Python language for Java platforms.
Here you will learn how to write scripts for automated execution of image processing pipelines and batch processing of multiple image files in Fiji. The author, Wayne Rasband, is at the Research Services Branch, National Institute of Mental Health, Bethesda, Maryland, USA.This tutorial is an introduction to the scripting interface of theįiji application, an open-source and enhanced version of the popular ImageJ program used for scientific image processing.
ImageJ is being developed on Mac OS X using its built in editor and Java compiler, plus the BBEdit editor and the Ant build tool. User-written plugins make it possible to solve almost any image processing or analysis problem. Custom acquisition, analysis and processing plugins can be developed using ImageJ's built in editor and Java compiler. ImageJ was designed with an open architecture that provides extensibility via Java plugins. Density or gray scale calibration is also available. Spatial calibration is available to provide real world dimensional measurements in units such as millimeters. The program supports any number of windows (images) simultaneously, limited only by available memory. All analysis and processing functions are available at any magnification factor. Image can be zoomed up to 32:1 and down to 1:32. It does geometric transformations such as scaling, rotation and flips. It supports standard image processing functions such as contrast manipulation, sharpening, smoothing, edge detection and median filtering.
It can create density histograms and line profile plots. It can calculate area and pixel value statistics of user-defined selections.
It is multithreaded, so time-consuming operations such as image file reading can be performed in parallel with other operations. It supports 'stacks', a series of images that share a single window. It can read many image formats including TIFF, GIF, JPEG, BMP, DICOM, FITS and 'raw'. It can display, edit, analyze, process, save and print 8-bit, 16-bit and 32-bit images. Downloadable distributions are available for Mac OS, Mac OS X and Linux. It runs, either as an online applet or as a downloadable application, on any computer with a Java 1.1 or later virtual machine. ImageJ is a public domain Java image processing program inspired by NIH Image for the Macintosh.
