This repository contains the source code for the PublicDecompWT tool. The tool can be build in Windows, Linux and Solaris. Note that it only decompresses compressed XRIT files. It includes a decoder for JPEG, WT and T4.

• GNU-GCC (g++, tested with version 4.2.x or previous version 3.x)
• GNU-make (make, tested with version 3.79.1)
• ar
• ranlib
• nmake as part of the Native Tools for VS

Navigate into xRITDecompress and call make. The compiled image will be stored in the xRITDecompress directory (image name xRITDecompress).

• Open the Native Tools Command Prompt for VS (x86 or x64, the output executable format will be set accordingly)
• Navigate into PublicDecompWT folder and run "nmake /f makefile.vc". The executable file will be in the xRITDecompress folder.
• To clean, navigate into PublicDecompWT folder and run "nmake /f makefile.vc clean" The procedure has been tested with Visual Studio Community 2019

• It is possible to build the conda package for Linux and Windows (64 bit)
• Prerequisites:
  • both platforms: conda and conda-build must be installed
  • Windows: Visual Studio Community 2019 must be installed
• Navigate to the conda folder in PublicDecompWT and execute:

conda build .

The source code is reported to be compilable with cygwin64, but the feature is not supported officially

You can specify:

--help: prints this list of options, stops execution
--version: prints current version, stops execution
-s:* source file (compulsory)
BITS=32 for 32 bits platforms or BITS=64 for 64 bits platforms.

Alternatively you can invoke the program with just the XRIT input file name:

$ xRITDecompress $XRITFilename

In Windows the program must be invoked with the .exe extension, i.e.

$ xRITDecompress.exe $XRITFilename

The output is the decompressed XRITFile in the current directory (same file name without extension C).

Under Linux/Unix you can run make testDx to verify the software works correctly.
