# EXPLANATION

#############

#
|
|
# This script was used to strip out the backgrounds from the living statue
|
|
# and crystal soul monster graphics. It takes as input three images:
|
|
#
|
|
# 1. back.png contains the backgrounds to be stripped out.
|
|
# 2. fore.png contains the original images.
|
|
# 3. mask.png contains black pixels where the original image should be assumed opaque.
|
|
#
|
|
# The actual magic that does this is contained in the two .fx scripts
|
|
# included in this directory.
|
|
#
|
|
# The script produces out.png containing the images with the background removed.
|
|
# Overall it works quite well; the regular crystal soul (normal and attack graphics)
|
|
# and the non-attacking living statue look pretty good with no additional
|
|
# manual adjustment. The other two crystal souls require a little noise removal,
|
|
# and the living statue attacks still require quite a bit of editing to get
|
|
# a usable result. Also, though the crystal soul attack looked pretty good,
|
|
# I used GIMP's levels tool to make it look closer to the original.
|
|
# (Red down to 240, Green up to 80, Blue up to 80, Alpha down to 230)
|
|
#
|
|
# As might be obvious from the below commands, running this script
|
|
# requires that ImageMagick is installed.
|
|
#
|
|
# Note that this script is not at all generic. If you wanted to use it
|
|
# on other images you would at minimum have to edit the canvas size
|
|
# specified in the command.
