pecomato1

Usage

Overview

pecomato is basically designed to display any kind of information embedded in picture files, as well as checking, filtering, extracting, removing, adding and fixing such information. In other words, it's a metadata processor.

It supports the following file formats: JPEG/JFIF, Adobe PSD and FFO, raw IPTC. And it knows about the following metadata formats: JFIF, IPTC, Exif, Adobe and Fotostation. More file and metadata formats might be supported later: TIFF, etc.

One of its main goals is to check the validity of parsed metadata as well as optionally check the strict compliance to official standards. On another hand, it aims to provide ways of fixing broken or not compliant chunks as well as providing general basic functions to manipulate the metadata.

Options

general options:

-v, --version

show version number then exit

-h, --help

show this usage help then exit

--list

list all supported embedded data structures

-l, --log-level NUM

define verbosity (see possible values below)

-c, --check-compliance

perform full checks to test the strict validity and compliance of structures to official formats

filtering and extracting options:

-b, --backup

create backup files of (re)written files if necessary

-d, --target-dir DIRNAME

target directory for all written files

-f, --fix

fix metadata inconsistencies when possible

extracting options:

-x, --extract TYPE

extract and save metadata to a standalone file (see below for a list of metadata types that can be extracted)

-t, --ext EXTENSION

define what filename extension to use when writing metadata that is extracted (default: .iptc)

-a, --append-ext

append extension to original filename when saving the extracted metadata (default: replace original file extension)

filtering options:

-i, --include EXPR

a filter expression describing the datasets to keep

-i, --include @FILE

or a file containing a list of datasets to keep, all other datasets will be filtered out. if not used, all datasets will be kept

-e, --exclude EXPR

a filter expression describing the datasets to filter out

-e, --exclude @FILE

a file containing a list of datasets to filter out, all other datasets will be kept. if not used all datasets will be kept

--edit EXPR

a filter edit expression describing the datasets to add

--edit @FILE

or a file containing a list of datasets to add. datasets won't be inserted if that breaks compliance to the standards

--test

don't override original file, create *.rewrite file. this option only affects rewriting of source files

dump options:

-w, --wrap NUM

max column for wrapping (num must be in range [8-1024]). default is to dump unwrapped

Possible ops

check

just check embedded data structures

dump

show embedded data (headers only)

dump-full

show all embedded data (including values)

dump-value

show requested value (headers only)

filter

filter embedded data (see -i, -e and --edit)

Dump-value expressions

IPTC.<record>

same as filter include/exclude expression, see below:

Filter include/exclude expressions

IPTC.<record>

where <record> can be either:

all: *

hexadecimal unary: 0xhhhh

hexadecimal range: 0xhhhh-0xhhhh

decimal unary: nnn:nnn

decimal ranges: nnn:nnn-nnn

nnn:*

examples:

IPTC.0x0219

IPTC.0x0300-0x0364

IPTC.3:0-100

Filter edit expressions

IPTC.<record>=<type>:<value>

where <record> can be either:

hexadecimal unary: 0xhhhh

decimal unary: nnn:nnn

where <type> can be either:

hex

text

and <value> is:

hex: [a-zA-Z0-9] pairs

text: any char (even widechars) on the line is taken as text, until

a newline is found

examples:

IPTC.0x0200=hex:0002

IPTC.0x0219=text:this is a keyword

Supported metadata for extraction

iptc

IPTC datasets

Possible log levels

0

quiet, no output at all

1

error messages only (default)

2

warning and error messages

3

informative, warning and error messages

4

all messages including debug ones

Supported input files

JPEG files (commonly .jpeg, .jpg, .jpe, .jfif, .jif)

Adobe Photoshop files (commonly .psd, .pdd, .ffo)

FotoStation files (commonly .fdp, .ipt)

standalone IPTC metadata (commonly .iptc)

Exit status

0

normal exit

1

usage error

2

asynchronous signal termination

3

normal exit, with warning(s)

4

normal exit, with error(s)

5

fatal error encountered

Examples

Check metadata structures of a JPEG file, only report errors

$ pecomato check file.jpg
