# TODO list:
# TODO Add message, either of these:
# If not a geotagged image file:
# A You haven't geotagged selected photos. Are you sure you want to continue?
# B Following photos don't have altitude value: XX XX XX Are you sure you want to continue?
# TODO IF INPUT IS A CSV FILE, DO NOT SUGGEST 'EXPORT ONLY' AS AN OPTION
# TODO if user chooses alternative 'Export CSV' only, do not crash if errtags or errnames encountered
#
# TODO Be more specific in which case errtags may crash the operation. For instance, if user has chosen only Temperature and ISO to be plotted on GNU Plot, do not crash in case where Focal Length is missing. In other words: be more specific in which conditions match the crash requirement, do not crash the process for nothing.
# TODO The script has only been tested on Canon 5D Mark 3 CR2 files. How does the script work with other Canon camera models? And what about Sony, Nikon?
#
# TODO Re-write, parse and simplify some scripts logics!

# Supported & tested camera raw pictures:
# Canon EOS 5D Mark 3
# TOOL REQUIREMENTS
# perl-exiftool
# kdialog (Qt5)
# qt5-tools (qdbus)
# coreutils (md5sum, echo etc..)
# netpbm (pgmhist)
# dcraw
# gawk
# gnuplot (+ Qt interface)
#
#
# OTHER REQUIREMENTS
#
# Recommended: Qt5 Dolphin file manager (dolphin)
#
# This script is meant to be run as a Dolphin File Manager script (Qt5). It gets file arguments straight from Dolphin
# You can run the script in bash (or execute Dolphin via bash) to get detailed script output (CLI messages, debug messages etc.)
