# Image::ExifTool::BZZ - Utility to decode BZZ compressed data - perldoc - [phpMan]

## NAME
    [Image::ExifTool::BZZ](https://www.chedong.com/phpMan.php/perldoc/Image%3A%3AExifTool%3A%3ABZZ/markdown) - Utility to decode BZZ compressed data

## SYNOPSIS
    This module is used by [Image::ExifTool](https://www.chedong.com/phpMan.php/perldoc/Image%3A%3AExifTool/markdown)

## DESCRIPTION
    This module contains definitions required by [Image::ExifTool](https://www.chedong.com/phpMan.php/perldoc/Image%3A%3AExifTool/markdown) to decode BZZ compressed data in
    DjVu images.

## NOTES
    This code is based on ZPCodec and BSByteStream of DjVuLibre 3.5.21 (see additional copyrights
    and the first reference below), which are covered under the GNU GPL license.

    This is implemented as [Image::ExifTool::BZZ](https://www.chedong.com/phpMan.php/perldoc/Image%3A%3AExifTool%3A%3ABZZ/markdown) instead of [Compress::BZZ](https://www.chedong.com/phpMan.php/perldoc/Compress%3A%3ABZZ/markdown) because I am hoping that
    someone else will write a proper [Compress::BZZ](https://www.chedong.com/phpMan.php/perldoc/Compress%3A%3ABZZ/markdown) module (with compression ability).
