# File: rotate_regions.config
#
# Description: User-defined Composite tag definitions to rotate MWG region tags
# (Metadata Working Group region, used by Picasa) and MP region tags
# (used by Microsoft Photo Library).
#
# Tag definitions and examples:
#
# RotateMWGRegionCW90
# RotateMWGRegionCW180
# RotateMWGRegionCW270
# These tags will rotate a MWG Region clockwise 90, 180, or 270 degrees.
# Example:
# exiftool -config rotate_regions.config "-RegionInfo<RotateMWGRegionCW90" FILE
#
# RotateMPRegionCW90
# RotateMPRegionCW180
# RotateMPRegionCW270
# These tags will rotate a MWG Region clockwise 90, 180, or 270 degrees.
# Example:
# exiftool -config rotate_regions.config "-RegionInfoMP<RotateMPRegionCW90" FILE
#
