Image::ExifTool::AFCP - Read/write AFCP trailer
SYNOPSIS
This module is used by Image::ExifTool
DESCRIPTION
This module contains definitions required by Image::ExifTool to extract information from the AFCP trailer. Although the AFCP specification
is compatible with various file formats, ExifTool currently only processes AFCP in JPEG images.
NOTES
AFCP is a specification which allows meta information (including IPTC) to be appended to the end of a file.
It is a poorly designed protocol because (like TIFF) it uses absolute offsets to specify data locations. This is a huge blunder because it
makes the AFCP information dependent on the file length, so it is easily invalidated by image editing software which doesn't recognize the
AFCP trailer to fix up these offsets when the file length changes. ExifTool will attempt to fix these invalid offsets if possible.
Scanning for AFCP information may be time consuming, especially when reading from a sequential device, since the information is at the end
of the file. In these instances, the ExifTool FastScan option may be used to disable scanning for AFCP information.

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;
