Bio-Formats supports reading lossless JPEG compressed DICOM files. However, it relies on the JAI Image I/O Tools native (platform-specific) library, which requires some extra steps to install:

1. Download the appropriate JAI Image I/O Tools native package for your platform.
2. Install the package into the applicable Java Runtime Environment (JRE).

Specific directions for Windows and Linux are below. The instructions are tailored toward people using Bio-Formats with ImageJ, but can be adapted for use in any of the other contexts as well.

1. Download and run jai_imageio-1_1-lib-windows-i586-jre.exe.
2. For the destination directory, choose:
   C:\Program Files\ImageJ\jre
   (unless you installed ImageJ somewhere else, or are using a different JRE location).
3. Start up ImageJ and give it a try.

• The JAI Image I/O Tools native library is not currently available for Mac OS X.
• Issue #103 on the jai-imageio-core development site tracks the problem.

1. Download jai_imageio-1_1-lib-linux-i586-jre.bin.
2. Place the file in your ImageJ JRE directory (e.g., ~/ImageJ/jre).
3. From the console, run:
   cd ~/ImageJ/jre chmod 755 jai_imageio-1_1-lib-linux-i586-jre.bin ./jai_imageio-1_1-lib-linux-i586-jre.bin
4. Once the files have unpacked, start up ImageJ and give it a try.
