=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.
