jai-imageio-core (standalone)

Build Status

NOTE: This is a fork of the original jai-imageio-core (which is no longer maintained).

This project adds read/write support for the following file types to Java's ImageIO:

  • wbmp
  • bmp
  • pcx
  • pnm
  • raw
  • tiff
  • gif (write)

The classes of this projects are not generally used directly, but through the SPI plugin mechanism of ImageIO. See the ImageIO guide for details.

This project is called 'standalone' as unlike the original jai-imageio-core it has removed dependencies to jai-core packages (javax.media.jai) and JPEG 2000 (jj2000). This version also does not include the C implementations from libJIIO, meaning that this version is platform independent and fully redistributable under the 3-clause BSD license in LICENSE.txt (and thus is Apache and GPL compatible).

JPEG 2000 support is available as an additional module jai-imageio-jpeg2000 as it has a different (non-GPL compatible) license.

If you are not concerned about GPL compatibility or source code availability, you might instead want to use https://github.com/geosolutions-it/imageio-ext/ which is actively maintained and extends the original imageio with many useful features, but depends on the binary distribution of jai_core.


There is NO ACTIVE DEVELOPMENT in this repository; any commits here are mainly to keep the build working with recent versions of Maven/Java - the date in the version number indicates the time of such modifications and should not have any effect on functionality.

You are however encouraged to raise a Github Pull Request with any suggested improvements.

You can also raise an issue - your stacktrace might still be of use to someone else.


This project requires Java 5 or newer. To build this project, use Apache Maven 2.2.1 or newer and run:

mvn clean install

To use jai-imageio-core from a Maven project, add:


To find the latest <version> above, see jai-imageio-core at BinTray

jai-imageio-core is mirrored to Maven Central. Alternatively you can use this explicit repository:
