Description :
The purpose of this module is to read/modify/rewrite meta-data segments in
JPEG (Joint Photographic Experts Group format) files, which can contain
comments, thumbnails, Exif information (photographic parameters), IPTC
information (editorial parameters) and similar data.
Each JPEG file is made of consecutive _segments_ (tagged data blocks), and
the actual row picture data. Most of these segments specify parameters for
decoding the picture data into a bitmap; some of them, namely the _COM_ment
and _APP_lication segments, contain instead meta-data, i.e., information
about how the photo was shot (usually added by a digital camera) and
additional notes from the photograph. These additional pieces of
information are especially valuable for picture databases, since the
meta-data can be saved together with the picture without resorting to
additional database structures. See the appendix about the structure of
JPEG files|Image::MetaData::JPEG::Structures/THE STRUCTURE OF JPEG PICTURES
for technical details.
This module works by breaking a JPEG file into individual segments. Each
file is associated to an _Image::MetaData::JPEG_ structure object, which
contains one _Image::MetaData::JPEG::Segment_ object for each segment.
Segments with a known format are then parsed, and their content can be
accessed in a structured way for display. Some of them can even be modified
and then rewritten to disk.
* $JPEG::show_warnings
This package variable must be used to inhibit the printing of warnings: if
it is false, warnings are silently ignored. Otherwise, warning messages
come with a detailed back-trace and description of the warning location.
$Image::MetaData::JPEG::show_warnings = undef;
