# File: example.config
|

#
|
||||
# Description: Example user configuration file for Image::ExifTool
|
||||
#
|
||||
# Notes: This example file shows how to define your own shortcuts and
|
||||
# add new EXIF, IPTC, XMP, PNG, MIE and Composite tags, as well
|
||||
# as how to specify preferred lenses for the LensID tag, and
|
||||
# define new file types and default ExifTool option values.
|
||||
#
|
||||
# Note that unknown tags may be extracted even if they aren't
|
||||
# defined, but tags must be defined to be written. Also note
|
||||
# that it is possible to override an existing tag definition
|
||||
# with a user-defined tag.
|
||||
#
|
||||
# To activate this file, rename it to ".ExifTool_config" and
|
||||
# place it in your home directory or the exiftool application
|
||||
# directory. (On Windows and Mac systems this must be done via
|
||||
# the command line since the GUI's don't allow filenames to begin
|
||||
# with a dot. Use the "rename" command in Windows or "mv" on the
|
||||
# Mac.) This causes ExifTool to automatically load the file when
|
||||
# run. Your home directory is determined by the first defined of
|
||||
# the following environment variables:
|
||||
#
|
||||
# 1. EXIFTOOL_HOME
|
||||
# 2. HOME
|
||||
# 3. HOMEDRIVE + HOMEPATH
|
||||
# 4. (the current directory)
|
||||
#
|
||||
# Alternatively, the -config option of the exiftool application
|
||||
# may be used to load a specific configuration file (note that
|
||||
# this must be the first option on the command line):
|
||||
#
|
||||
# exiftool -config example.config ...
|
||||
#
|
||||
# This example file defines the following 16 new tags as well as
|
||||
# a number of Shortcut and Composite tags:
|
||||
#
|
||||
# 1. EXIF:NewEXIFTag
|
||||
# 2. GPS:GPSPitch
|
||||
# 3. GPS:GPSRoll
|
||||
# 4. IPTC:NewIPTCTag
|
||||
# 5. XMP-xmp:NewXMPxmpTag
|
||||
# 6. XMP-exif:GPSPitch
|
||||
# 7. XMP-exif:GPSRoll
|
||||
# 8. XMP-xxx:NewXMPxxxTag1
|
||||
# 9. XMP-xxx:NewXMPxxxTag2
|
||||
# 10. XMP-xxx:NewXMPxxxTag3
|
||||
# 11. XMP-xxx:NewXMPxxxStruct
|
||||
# 12. PNG:NewPngTag1
|
||||
# 13. PNG:NewPngTag2
|
||||
# 14. PNG:NewPngTag3
|

# 15. MIE-Meta:NewMieTag1
|

# 16. MIE-Test:NewMieTag2
