NOTES => q{
The FlashPix file format, introduced in 1996, was developed by Kodak,
Hewlett-Packard and Microsoft. Internally the FPX file structure mimics
that of an old DOS disk with fixed-sized "sectors" (usually 512 bytes) and a
"file allocation table" (FAT). No wonder this image format never became
popular. However, some of the structures used in FlashPix streams are part
of the EXIF specification, and are still being used in the APP2 FPXR segment
of JPEG images by some digital cameras from manufacturers such as FujiFilm,
Hewlett-Packard, Kodak and Sanyo.
ExifTool extracts FlashPix information from both FPX images and the APP2
FPXR segment of JPEG images. As well, FlashPix information is extracted
from DOC, PPT, XLS (Microsoft Word, PowerPoint and Excel) documents, VSD
(Microsoft Visio) drawings, and FLA (Macromedia/Adobe Flash project) files
since these are based on the same file format as FlashPix (the Windows
Compound Binary File format). Note that ExifTool identifies any
unrecognized Windows Compound Binary file as a FlashPix (FPX) file. See
L<http://graphcomp.com/info/specs/livepicture/fpx.pdf> for the FlashPix
specification.
Note that Microsoft is not consistent with the time zone used for some
date/time tags, and it may be either UTC or local time depending on the
software used to create the file.

Image::ExifTool::FlashPix - Read FlashPix meta information
=head1 SYNOPSIS
This module is used by Image::ExifTool
=head1 DESCRIPTION
This module contains routines required by Image::ExifTool to extract
