=head1 NAME
Image::ExifTool::InfiRay - InfiRay IJPEG thermal image metadata
=head1 SYNOPSIS
This module is loaded automatically by Image::ExifTool when required.
=head1 DESCRIPTION
This module contains definitions required by Image::ExifTool to interpret
metadata and thermal-related information of pictures saved by the InfiRay
IJPEG SDK, used in cameras such as the P2 Pro.
