* How to proceed?

System Requirement

  1. A Java 2 platform (Java Runtime Environnment version 1.2 or 1.3) is required to run Raja.

  2. You need the "Java Advanced Imaging" codecs to be able to save the images computed by Raja. See:

    http://www.java.sun.com/products/java-media/jai/

    You actually only need the jai_codec.jar file and the jai_core.jar file from the JAI library. If you don't install the JAI, you will still be able to compute images and display them with Raja. However, you won't be able to save them.

Installation

  1. Download the latest version of raja.

  2. Extract the downloaded Raja archive (e.g with GNU tar or WinZip).

    We assume in the following that you installed Raja in (raja_dir):

    (Unix) /usr/local/raja
    (Windows) C:\Raja

  3. Modify the scripts in the raja_dir/bin subdirectory to set the JAI_CODEC and JAI_CORE variables, according to JAI's installation directory. If you are running Windows, you also need to set the RAJA_HOME variable in these scripts.

    Scripts to modify:

    (Unix) /usr/local/raja/bin/raja and /usr/local/raja/bin/xraja
    (Windows) C:\Raja\bin\raja.bat and C:\Raja\bin\xraja.bat

  4. Add raja_dir's bin subdirectory to your PATH variable:

    (Unix) export PATH=/usr/local/raja/bin:$PATH
    (Windows) PATH=%PATH%;C:\Raja\bin

    Note that step (4) above is not required, but it allows you to run the scripts without specifying the path to Raja's installation directory.

For more information, look at the README file from the source tree.
