# File: picasa_faces.config
#
# Description: User-defined Composite tag definitions to convert face regions
# in .picasa.ini files to MWG region tags (Metadata Working Group
# region, used by Picasa) and MP region tags (used by Microsoft
# Photo Library).
#
# Tag definitions and examples:
#
# PicasaToMWGRegion
# This will create the MWG region tag but will filter out the regions
# that are still unnamed in Picasa. Picasa defaults to naming these
# regions 'ffffffffffffffff' but normally will not save these to file.
# Example:
# exiftool -config picasa_faces.config "-RegionInfo<PicasaToMWGRegion" FILE
#
# PicasaToMPRegion
# This will create the MP region tag but will filter out the regions that
# are still unnamed in Picasa. Picasa defaults to naming these regions
# 'ffffffffffffffff' but normally will not save these to file.
# Example:
# exiftool -config picasa_faces.config "-RegionInfoMP<PicasaToMPRegion" FILE
#
# PicasaRegionNames
# Returns a list of the region names associated with the file. This
# allows copying of the region names to XMP:Subject and/or IPTC:Keywords.
# It also allows checking to see if regions need to be updated.
# Example:
# exiftool -config picasa_faces.config "-XMP:Subject<PicasaRegionNames" FILE
#
# PicasaToMWGRegionUnfiltered
# This will create the MWG region tag. This version does not filter out
# the unnamed regions. Picasa normally will filter out unnamed regions
# when it saves regions in the file.
# Example:
# exiftool -config picasa_faces.config "-RegionInfo<PicasaToMWGRegionUnfiltered" FILE
#
# PicasaToMPRegionUnfiltered
# This will create the MP region tag. This version does not filter out
# the unnamed regions. Picasa normally will filter out unnamed regions
# when it saves regions in the file.
# Example:
# exiftool -config picasa_faces.config "-RegionInfoMP<PicasaToMPRegionUnfiltered" FILE
#
# Notes: The face names are loaded from the Picasa contacts file, which
# defaults to:
#
# C:/Users/MainUser/AppData/Local/PicasaData/Google/Picasa2/contacts/contacts.xml
#
# The default contacts file may be changed by editing the value
# of $contactXML below, or on the command line with ExifTool 9.90
# or later via the -userParam option, eg:
# -userparam PicasaContactsFile=/path/to/contacts.xml
#
# Requires: ExifTool version 8.82 or later (9.90 or later for -userparam)
#
# Revisions: 2015/03/07 - Bryan K. Williams (aka StarGeek) Created
# 2015/03/12 - PH Minor changes, optimizations and reformatting
# 2015/05/11 - BKW Fix bug where Picasa writes region data for
# rotated NEF and CR2 images as if the orientation
# is not rotated.
# 2015/05/12 - PH Minor code tweaks
# 2015/10/26 - BKW Round off area sizes to 7 decimal places
# 2016/01/18 - BKW Improved rounding algorithm
# 2016/05/14 - BKW Increased rounding to 9 decimal places (Max Picasa accepts),
# moved rounding operation to subroutine
