ImageJ
The source code of the original ImageJ is available at:
ImageJ2
The source code of ImageJ2 is very modular; i.e., it is organized into well-separated projects. This separation offers many advantages for efficient software development and it is well worth investing a little bit of time to understand.
Where is the code?
You can search the source code at search.imagej.net using the GitHub button!
All source code is on GitHub.
- Each project exists in its own GitHub organization.
- Each organization contains multiple source code repositories.
- Each repository corresponds to one Java library (.jar file).
| Logo | Organization | Purpose |
|---|---|---|
 |
SciJava | Common utilities, plugin infrastructure, scripting, the context |
 |
ImageJ2 | A general-purpose image processing application |
 |
ImgLib2 | Generic multi-dimensional data processing |
 |
SCIFIO | Extensible image file I/O |
 |
Fiji | A “batteries-included” distribution of ImageJ and ImageJ2 |
See the Architecture page for more information about the relationship between these projects.
What is the license?
Most is BSD-2 (permissive); some is GPL (copyleft). See the Licensing page.
Building from source
Virtually all of these repositories have a top-level pom.xml file, identifying them as Maven projects.
To build a Maven project:
- Install Maven.
- Clone the source repository of interest.
- Type
mvnfrom the top-level directory.
Advanced instructions for building, or modifying, the source code are available for specific development environments:
Note that these tutorials are targeted towards ImageJ2, but would apply to any Maven-based project.
Javadocs
Javadoc for all SciJava-related projects can be found online:
