Supported image formats are JPEG, Canon CRW and Canon THM. Read-only support is currently available for TIFF format and includes TIFF-based RAW formats such as Nikon NEF, Canon CR2, Sony SR2 and Pentax PEF. .SH ACTIONS The \fIaction\fP argument is only required if it is not clear 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 and thumbnail image files. .TP .B in | insert Insert metadata from corresponding *.exv 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. .TP .B rm | delete Delete image metadata from the files. .TP .B ad | adjust Adjust EXIF timestamps by the given time. Requires option \fB\-a\fP \fItime\fP. .TP .B mo | modify Apply commands to modify (add, set, delete) the EXIF/IPTC 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. 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 any of the proprietary Nikon makernote ISO tags to the regular Exif ISO tag, Exif.Photo.ISOSpeedRatings. Overwrites an existing Exif ISO tag. .SH OPTIONS .TP .B \-h Display help and exit. .TP .B \-V Show the program version and exit. .TP .B \-v Be verbose during the program run. .TP .B \-b Don't show large binary values. .TP .B \-u Don't show unknown tags. .TP .B \-k Preserve file timestamps when updating files (keep). Can be used with all options which update files. The flag is ignored by read-only options. .TP .B \-t Set the file timestamp according to the EXIF create timestamp in addition to renaming the file (overrides \fB\-k\fP). This option is only used with the 'rename' action. .TP .B \-T Only set the file timestamp according to the EXIF create timestamp, do not rename the file (overrides \fB\-k\fP). This option is only used with the 'rename' action. .TP .B \-f Do not prompt before overwriting existing files (force overwrite). .TP .B \-F Do not prompt before renaming files (Force rename). Appends '_1' ('_2', ...) to the name of the new file. .TP .B \-a \fItime\fP Time adjustment in the format [\-]HH[:MM[:SS]]. This option is only used with the 'adjust' action. Examples: 1 adds one hour, 1:01 adds one hour and one minute, \-0:00:30 subtracts 30 seconds. .TP .B \-p \fImode\fP Print mode for the 'print' action. Possible modes are: .br s : print a summary of the EXIF metadata (the default) .br t : interpreted (translated) EXIF data (shortcut for -Pkyct) .br v : plain EXIF data values (shortcut for -Pxgnycv) .br h : hexdump of the EXIF data (shortcut for -Pxgnycsh) .br i : IPTC data values .br c : JPEG comment .TP .B \-P \fIcols\fP Print columns for the Exif taglist ('print' action), allows detailed control of the print output. Valid are: .br x : print a column with the tag value .br g : group name .br k : key .br l : tag label .br n : tag name .br y : type .br c : number of components (count) .br s : size in bytes .br v : plain data value .br t : interpreted (translated) data .br h : hexdump of the data .TP .B \-d \fItgt\fP Delete target(s) for the 'delete' action. Possible targets are: .br a : all supported metadata (the default) .br e : EXIF section .br t : EXIF thumbnail only .br i : IPTC data .br c : JPEG comment .TP .B \-i \fItgt\fP Insert target(s) for the 'insert' action. Possible targets are the same as those for the \fB\-d\fP option. Only JPEG thumbnails can be inserted, they need to be named \fIfile\fP\-thumb.jpg. .TP .B \-e \fItgt\fP Extract target(s) for the 'extract' action. Possible targets the same as those for the \fB\-d\fP option. .TP .B \-r \fIfmt\fP Filename format for the 'rename' action. The format string follows \fBstrftime\fP(3). Default filename format is %Y%m%d_%H%M%S. .TP .B \-c \fItxt\fP Jpeg comment string to set in the image ('modify' action). .TP .B \-m \fIfile\fP Command file for the 'modify' action. .TP .B \-M \fIcmd\fP Command line for the 'modify' action. The format for the commands is the same as that of the lines of a command file. .TP .B \-l \fIdir\fP Location (directory) for files to be inserted or extracted. .TP .B \-S \fI.suf\fP Use suffix \fI.suf\fP for source files in 'insert' action. .SH COMMANDS Commands for the 'modify' action can be read from a command file, e.g., .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. .sp 1 When writing EXIF/IPTC 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 a tag (requires only a \fIkey\fP). .TP .I key Exiv2 EXIF or IPTC key. .TP .I type .B Byte | Ascii | Short | Long | Rational | Undefined | SShort | SLong | SRational | Comment for EXIF keys, and .br .B String | Date | Time | Short | Undefined for IPTC keys. .sp 1 A default \fItype\fP is used if none is explicitely 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 double quotes ("\fIvalue\fP"). .sp 1 The format of EXIF \fBComment\fP values includes an optional charset specification at the beginning: .sp 1 .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 IPTC \fBDate\fP values is YYYY\-MM\-DD (year, month, day) that for IPTC \fBTime\fP values is HH:MM:SS+|\-HH:MM, where HH:MM:SS refers to local hour, minute and seconds and +|\-HH:MM refers to hours and minutes ahead or behind Universal Coordinated Time (+|\- means either a + or a \- sign is required). .SS Command file format Empty lines and lines starting with \fB#\fP in a command file are ignored (comments). Remaining lines are commands as described above. .SH EXAMPLES .TP exiv2 *.jpg Prints a summary of the EXIF information for all JPEG files in the directory. .TP exiv2 -pi image.jpg Prints the IPTC metadata of the image. .TP exiv2 rename image.jpg Renames image.jpg (taken on 13\-Nov\-05 at 22:58:31) to 20051113_225831.jpg .TP exiv2 ex img1.jpg img2.jpg Extracts metadata from the two files into files img1.exv and img2.exv. .TP exiv2 \-et img1.jpg img2.jpg Extracts the EXIF thumbnails from the two files into img1\-thumb.jpg and img2\-thumb.jpg. .TP exiv2 \-it img1.jpg img2.jpg Inserts (copies) metadata from img1.exv to img1.jpg and from img2.exv to img2.jpg. .TP .nf exiv2 \-M"set Exif.Photo.UserComment charset=Ascii New EXIF comment" image.jpg .fi Sets the EXIF comment to an ASCII string. .TP .nf exiv2 \-M"set Exif.GPSInfo.GPSLatitude 4/1 15/1 33/1" \\ \-M"set Exif.GPSInfo.GPSLatitudeRef N" image.jpg .fi Sets the latitude to 4 degrees, 15 minutes and 33 seconds north. The EXIF standard stipulates that the GPSLatitude tag consists of three Rational numbers for the degrees, minutes and seconds of the latitude and GPSLatitudeRef contains either 'N' or 'S' for north or south latitude respectively. .SH SEE ALSO .TP .I http://www.exiv2.org/sample.html#modify Sample command file. .TP .I http://www.exiv2.org/metadata.html Taglists with \fIkey\fP and default \fItype\fP values. .SH AUTHOR .B exiv2 was written by Andreas HUGGEL . .PP This manual page was originally written by KELEMEN Peter , for the Debian project.
