Image::ExifTool::MWG(3) User Contributed Perl Documentation Image::ExifTool::MWG(3)NAME
Image::ExifTool::MWG - Metadata Working Group support
SYNOPSIS
# enable MWG tags (strict mode enabled by default)
use Image::ExifTool::MWG;
# disable MWG strict mode
$Image::ExifTool::MWG::strict = 0;
DESCRIPTION
The MWG module contains tag definitions which are designed to simplify implementation of the Metadata Working Group guidelines. These
special MWG composite tags are enabled simply by loading this module:
use Image::ExifTool::MWG;
When the MWG module is loaded, "strict MWG conformance" is enabled by default. In this mode, ExifTool will generate a Warning tag instead
of extracting EXIF, IPTC and XMP from non-standard locations. The strict mode may be disabled by setting the MWG "strict" flag to zero
(either before or after loading the MWG module):
$Image::ExifTool::MWG::strict = 0;

Image::ExifTool::BZZ(3) User Contributed Perl Documentation Image::ExifTool::BZZ(3)NAME
Image::ExifTool::BZZ - Utility to decode BZZ compressed data
SYNOPSIS
This module is used by Image::ExifTool
DESCRIPTION
This module contains definitions required by Image::ExifTool 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 instead of Compress::BZZ because I am hoping that someone else will write a proper
Compress::BZZ module (with compression ability).
