## What

This is repo contains a console application **CZIrepair** which can be used to fix a certain type of malformed CZIs. It is only one type of corruption that the

tool can fix - when the width/height of a sub-block is reported differently in the CZI-file than it actually is, and only in the case of JPGXR-compressed data.

The tool will write the width/height determined from the JPGXR-compressed data to corresponding data-structures at CZI-level.

The tool offers two modes of operation:

* There is a dry-run mode, where the tool will only read the CZI-file and report the issues it found.

* There is a patch mode, where the corruption is fixed in-place (i.e. the original file is modified).

This tool is based on the [libCZI library](https://github.com/ZEISS/libczi). This repo contains a modified version of the libCZI library, which is used by the CZIrepair tool.
