Command-line usage

In command-line, running:

$ mrz <filename>

will process a given filename, extracting the MRZ information it finds and printing it out in tabular form. Running mrz --json <filename> will output the same information in JSON. Running mrz --save-roi <roi.png> will, in addition, extract the detected MRZ (“region of interest”) into a separate png file for further exploration. Note that the tool provides a limited support for PDF files – it attempts to extract the first DCT-encoded image from the PDF and applies the recognition on it. This seems to work fine with most scanner-produced one-page PDFs, but has not been tested extensively.
