Merge pull request #2290 from stweil/libarchive 
Add initial support for traineddata files in standard archive formats
 2019-03-05 17:42:13 +01:00
Stefan Weil
1c7e00611b Add initial support for traineddata files in standard archive formats 
This requires libarchive-dev.

Tesseract can now load traineddata files in any of the archive formats
which are supported by libarchive. Example of a zipped BagIt archive:

    $ unzip -l /usr/local/share/tessdata/zip.traineddata
    Archive:  /usr/local/share/tessdata/zip.traineddata

`combine_tessdata -d` and `combine_tessdata -u` also work.

The traineddata files in the new format can be generated with
standard tools like zip or tar.

More work is needed for other training tools and big endian support.

25fa392887 Added an additional optional --tmp_dir parameter to specify the temporary directory in which tesstrain.py creates the training temporary files. The main reason is due to the slow R/W on HDD, if anyone wants to speed up this process can use as tmp_dir a directory on an SSDrive 2019-03-04 13:26:53 +00:00
