ImageJ

ImageJ is public domain software for processing and analyzing scientific images.

It is written in Java, which allows it to run on many different platforms.

For further information, see:

• The ImageJ website, the primary home of this project.
• The ImageJ wiki, a community-built knowledge base covering ImageJ and its derivatives and flavors, including ImageJ2, Fiji, and others.

Using ImageJ as a dependency

To use ImageJ as a library in your Maven project, add the dependency:

<dependency>
  <groupId>net.imagej</groupId>
  <artifactId>ij</artifactId>
  <version>1.53j</version>
</dependency>

Where 1.53j is the version of ImageJ you would like to use:

• Versions up to 1.48q are in the SciJava Maven repository.
• Versions starting with 1.48r are on Maven Central.
• Be aware that versions prior to 1.53k may not identically match the corresponding release tags here in this repository.

Building from source

Prerequisites

It is recommended to build ImageJ with OpenJDK 8 or 11. Building with newer versions (17, 21, 25) is not currently supported, due to ImageJ bytecode targeting Java 1.6 as minimum Java version.

With Ant

The Apache Ant utility will compile and run ImageJ using the build.xml file in this directory. There is a version of Ant at

https://imagej.nih.gov/ij/download/tools/ant/ant.zip

set up to use the JVM distributed with the Windows version of ImageJ. The README included in the ZIP archive has more information.

With Maven

You can compile and run ImageJ using the Maven build tool:

| Command | Action | |-----------------------|-----------------------------------------------------------------------| | mvn | Compile and package ImageJ into a JAR file in the target directory. | | mvn -Pexec | Compile and then run ImageJ. | | mvn javadoc:javadoc | Generate the project Javadoc in the target/apidocs directory. |
