# Exiv2 Sample Applications
|
||||
|
||||
Exiv2 is a C++ library and a command line utility to read, write, delete and modify Exif, IPTC, XMP and ICC image metadata. Exiv2 also features a collection of sample and test command-line programs. Please be aware that while the program _**exiv2**_ enjoys full support from Team Exiv2, the other programs have been written for test, documentation or development purposes. You are expected to read the code to discover the specification of programs other than _**exiv2**_.

|:-- |:--- |
|
||||
| all | All metadata |
|
||||
| filesystem | Filesystem metadata |

||||
| exif | Exif metadata |
|
||||
| iptc | Iptc metadata |
|
||||
| xmp | Xmp metadata |
|
||||
| file | path to image |
|
||||
|
||||
This program dumps metadata from an image in JSON format. _Code: [exiv2json.cpp](samples/exiv2json.cpp)_
|
||||
|
||||
exiv2json has a recursive parser to encode XMP into Vectors and Objects. XMP data is XMP and can contain XMP `Bag` and `Seq` which are converted to JSON Objects and Arrays. Exiv2 presents data in the format: Family.Group.Tag. For XMP, results in "flat" output such such as:
|
||||
|
||||
```
|
||||
$ exiv2 -px ~/Stonehenge.jpg
|
||||
Xmp.xmp.Rating XmpText 1 0
|
||||
Xmp.xmp.ModifyDate XmpText 25 2015-07-16T20:25:28+01:00
|
||||
Xmp.dc.description LangAlt 1 lang="x-default" Classic View
|
||||
```
|
||||
|
||||
exiv2json parses the Exiv2 'Family.Group.Tag' data and restores the structure of the original data in JSON. _Code: [exiv2json.cpp](samples/exiv2json.cpp)_
|
||||
|
||||
```
|
||||
$ exiv2json -xmp http://clanmills.com/Stonehenge.jpg

<div id="geotag">
|
||||
|
||||
#### geotag
|
||||
|
||||
```
|
||||
Usage: geotag {-help|-version|-dst|-dryrun|-ascii|-verbose|-adjust value|-tz value|-delta value}+ path+
|
||||
```
|
||||
|
||||
Geotag reads one or more GPX files and adds GPS Tages to images. _Code: [geotag.cpp](samples/geotag.cpp)_
|
||||
|
||||
If the path is a directory, geotag will read all the files in the directory. It constructs a time dictionary of position data, then updates every image with GPS Tags.
|
||||
|
||||
| Arguments | Description |
|
||||
|:-- |:--- |
|
||||
| -ascii | Output in ascii (not UTF8). Prints `deg` instead of °. |
|
||||
| -dst | Apply 1 hour adjustment for daylight saving time. |
|
||||
| -dryrun | Read arguments and print report. Does not modify images. |
|
||||
| -verbose | Report progress. |
|
||||
| -adjust value | Add/subtract time from image data. |
|
||||
| -tz value | Specify time zone. For example PST = -8:00 |
|
||||
| -delta value | Correction between Image DataTime and GPS time. |
|
||||
|
||||
I use this program frequently. I have a little Canon camera which I take when I run. My Samsung Galaxy Watch uploads my runs to Strava and I download the GPX. If I'm in another time-zone and have forgotten to change the time setting in the camera, I use `-adjust` to alter the images. The GPX time is always correct, however the camera is normally off by seconds or minutes. This option enables you to correct for inaccuracy in the setting of the camera time.

.SH ACTIONS
|
||||
The \fIaction\fP argument is only required if it is not clear from the
|
||||
\fIoptions\fP which action is implied.
|
||||
.TP
|
||||
.B pr | print
|
||||
Print image metadata. This is the default action, i.e., the command
|
||||
\fIexiv2 image.jpg\fP will print a summary of the image Exif metadata.
|
||||
.TP
|
||||
.B ex | extract
|
||||
Extract metadata to *.exv, XMP sidecar (*.xmp) and thumbnail image files.
|
||||
Modification commands can be applied on-the-fly.
|
||||
.TP
|
||||
.B in | insert
|
||||
Insert metadata from corresponding *.exv, XMP sidecar (*.xmp) and
|
||||
thumbnail files. Use option \fB\-S\fP \fI.suf\fP to change the suffix
|
||||
of the input files. Since files of any supported format can be used as
|
||||
input files, this command can be used to copy the metadata between
|
||||
files of different formats. Modification commands can be applied
|
||||
on-the-fly.
|
||||
.TP
|
||||
.B rm | delete
|
||||
Delete image metadata from the files.
|
||||
.TP
|
||||
.B ad | adjust
|
||||
Adjust Exif timestamps by the given time. Requires at least one of the
|
||||
options \fB\-a\fP \fItime\fP, \fB\-Y\fP \fIyrs\fP, \fB\-O\fP
|
||||
\fImon\fP or \fB\-D\fP \fIday\fP.
|
||||
.TP
|
||||
.B mo | modify
|
||||
Apply commands to modify (add, set, delete) the Exif, IPTC and XMP
|
||||
metadata of image files. Requires option \fB\-c\fP, \fB\-m\fP or
|
||||
\fB\-M\fP.
|
||||
.TP
|
||||
.B mv | rename
|
||||
Rename files and/or set file timestamps according to the Exif create
|
||||
timestamp. Uses the value of tag Exif.Photo.DateTimeOriginal or, if
|
||||
not present, Exif.Image.DateTime to determine the timestamp. The
|
||||
filename format can be set with \fB\-r\fP \fIfmt\fP, timestamp options
|
||||
are \fB\-t\fP and \fB\-T\fP.
|
||||
.TP
|
||||
.B fi | fixiso
|
||||
Copy the ISO setting from one of the proprietary Nikon or Canon
|
||||
makernote ISO tags to the regular Exif ISO tag,
|
||||
Exif.Photo.ISOSpeedRatings. Does not overwrite an existing standard
|
||||
Exif ISO tag.
|
||||
.TP
|
||||
.B fc | fixcom
|
||||
Fix the character encoding of Exif Unicode user comments. Decodes the
|
||||
comment using the auto-detected or specified character encoding and
|
||||
writes it back in UCS-2. Use option \fB\-n\fP to specify the current
|
||||
encoding of the comment if necessary.

When \fB\-V\fP is combined with \fB\-v\fP (Verbose version), build information
|
||||
is printed to standard output along with a list of shared libraries which
|
||||
have been loaded into memory. Verbose version is supported on Windows
|
||||
(MSVC, Cygwin and MinGW builds), MacOSX and Linux and is provided
|
||||
for test and debugging.

|
||||
program run (quiet). Note that options \fB\-v\fP and \fB\-q\fP can be
|
||||
used at the same time.
|
||||
.TP
|
||||
.B \-Q \fIlvl\fP
|
||||
Set the log-level to 'd'(ebug), 'i'(nfo), 'w'(arning), 'e'(rror)
|
||||
or 'm'(ute). The default log-level is 'w'. \fB\-Qm\fP is equivalent
|
||||
to \fB\-q\fP. All log messages are written to standard error.
|

can be used to grep info for several keys. When the library is build with C++11,
|
||||
keys are matched using std::regex::extended. When build without C++11, keys are
|
||||
processed with the system regular expression engine: see man 3 regex. Platforms which do not support
|
||||
regex use key for a substring match. You can determine the availability of regex
|
||||
using the command: exiv2 -v -V -g have_regex -g cplusplus.

.sp 1
|
||||
.nf
|
||||
exiv2 \-m cmd.txt image.jpg
|
||||
.fi
|
||||
.sp 1
|

or given on the command line, as in
|
||||
.sp 1
|
||||
.nf
|
||||
exiv2 \-M"add Iptc.Application2.Credit String Mr. Smith" image.jpg
|
||||
.fi
|
||||
.sp 1
|
||||
Note the quotes. Multiple \fB\-m\fP and \fB\-M\fP options can be combined,
|
||||
and a non-standard XMP namespace registered.
|
||||
.sp 1
|
||||
.nf
|

.fi
|

.sp 1
|
||||
When writing Exif, IPTC and XMP metadata,
|
||||
.B exiv2
|
||||
enforces only a correct
|
||||
metadata structure. It is possible to write tags with types and values
|
||||
different from those specified in the standards, duplicate Exif tags,
|
||||
undefined tags, or incomplete metadata. While
|
||||
.B exiv2
|
||||
is able to read
|
||||
all metadata that it can write, other programs may have difficulties
|
||||
with images that contain non standard-conforming metadata.
|
||||
.SS Command format
|
||||
The format of a command is
|
||||
.sp 1
|
||||
.nf
|
||||
\fBset | add | del\fP \fIkey\fP [[\fItype\fP] \fIvalue\fP]
|
||||
.fi
|
||||
.TP
|
||||
.B set
|
||||
Set the \fIvalue\fP of an existing tag with a matching \fIkey\fP or
|
||||
add the tag.
|
||||
.TP
|
||||
.B add
|
||||
Add a tag (unless \fIkey\fP is a non\-repeatable IPTC key; nothing
|
||||
prevents you from adding duplicate Exif tags).
|
||||
.TP
|
||||
.B del
|
||||
Delete all occurrences of a tag (requires only a \fIkey\fP).
|
||||
.TP
|
||||
.I key
|
||||
Exiv2 Exif, IPTC or XMP key.
|
||||
.TP
|
||||
.I type
|
||||
.B Byte | Ascii | Short | Long | Rational | Undefined | SShort | SLong | SRational | Comment
|
||||
for Exif keys,
|
||||
.br
|
||||
.B String | Date | Time | Short | Undefined
|
||||
for IPTC keys, and
|
||||
.br
|
||||
.B XmpText | XmpAlt | XmpBag | XmpSeq | LangAlt
|
||||
for XMP keys.
|
||||
.sp 1
|
||||
A default \fItype\fP is used if none is explicitly given. The default
|
||||
is determined based on \fIkey\fP.
|
||||
.TP
|
||||
.I value
|
||||
The remaining text on the line is the value. It can optionally be
|
||||
enclosed in single quotes ('\fIvalue\fP') or double quotes ("\fIvalue\fP").
|
||||
.sp 1
|
||||
The value is optional. Not providing any value is equivalent to an
|
||||
empty value ("") and is mainly useful to create an XMP array property,
|
||||
e.g., a bag.
|
||||
.sp 1
|
||||
The format of Exif \fBComment\fP values includes an optional charset
|
||||
specification at the beginning:
|
||||
.br
|
||||
.B [charset=Ascii|Jis|Unicode|Undefined ]\fIcomment\fP
|
||||
.sp 1
|
||||
.B Undefined
|
||||
is used by default if the value doesn't start with a charset
|
||||
definition.
|
||||
.sp 1
|
||||
The format for an IPTC \fBDate\fP value is:
|
||||
.br
|
||||
YYYY\-MM\-DD (year, month, day)
|
||||
.sp 1
|
||||
The format for an IPTC \fBTime\fP value is:
|
||||
.br
|
||||
HH:MM:SS (hours, minutes, seconds)
|
||||
.br
|
||||
and may optionally be followed by:
|
||||
.br
|
||||
\-HH:MM or +HH:MM (hours, minutes ahead/behind UTC)
|
||||
.sp 1
|
||||
The format of \fBRational\fP (and \fBSRational\fP) is one of:
|
||||
.br
|
||||
integer
|
||||
.br
|
||||
integer-numerator/integer-denominator
|
||||
.br
|
||||
Fnumber
|
||||
.br
|
||||
fnumber
|
||||
.sp 1
|
||||
Rational Examples:
|
||||
.br
|
||||
exiv2 "-Mset Exif.Photo.MaxApertureValue 557429/62500" X.jpg
|
||||
.br
|
||||
exiv2 "-Mset Exif.Photo.MaxApertureValue F5.6" X.jpg
|
||||
.sp 1
|
||||
The Rational format Fnumber (or fnumber) is for the convenience of setting aperture values. Aperture values
|
||||
are stored in Exif is an \fBAPEX\fP value which can be evaluated by the expression:
|
||||
.sp 1
|
||||
apex-value = log(Fnumber) * 2.0 / log(2.0)
|
||||
.br
|
||||
Fnumber = exp(apex-value * log(2.0) / 2.0)
|
||||
.sp 1
|
||||
The Rational format Fnumber is valid for any \fBRational\fP, even when the key is not an Aperture.
|
||||
More information about \fBAPEX\fP value is available from: http://en.wikipedia.org/wiki/APEX_system
|
||||
.sp 1
|
||||
The format of XMP \fBLangAlt\fP values includes an optional language qualifier:
|
||||
.br
|
||||
.B lang="\fIlanguage-code\fP\fI" text\fP
|
||||
.sp
|
||||
lang="x-default" is used if the value doesn't start with a language qualifier.
|
||||
.sp 1
|
||||
exiv2 -M'set Xmp.dc.title lang="de-DE" Euros' X.jpg
|
||||

exiv2 -M'set Xmp.dc.title All others pay cash' X.jpg
|
||||
.sp 1
|
||||
To remove a language specification, set the value to '' (empty string)
|
||||
.br
|
||||
exiv2 -M'set Xmp.dc.title lang="en-US"' X.jpg
|
||||
.sp 1
|

To remove all language specifications, delete the key:
|
||||
.br
|
