jpylyzer.py [-h] [-v] [--verbose] [--recursive|-r] jp2In

jp2In : input JP2 image(s) or folders

-h, --help : show this help message and exit

-v, --version : show program's version number and exit

--verbose : report test results in verbose format

--recursive : recrursive descend into a folder and sub-folders analysing all .jp2 files

Output is directed to the standard output device (stdout).

jpylyzer.py rubbish.jp2 > rubbish.xml

In the above example, output is redirected to the file 'rubbish.xml'.

1. toolInfo: tool name (jpylyzer) + version.
2. fileInfo: name, path, size and last modified time/date of input file.
3. isValidJP2: True/False flag indicating whether file is valid JP2.
4. tests: tree of test outcomes, expressed as True/False flags. A file is considered valid JP2 only if all tests return True. Tree follows JP2 box structure. By default only tests that returned False are reported, which results in an empty tests element for files that are valid JP2. Use the --verbose flag to get all test results.
5. properties: tree of image properies. Follows JP2 box structure. Naming of properties follows ISO/IEC 15444-1 Annex I (JP2 file format syntax) and Annex A (Codestream syntax).
