By default, PNG images are written to current directory. This can be overridden
with -o <path>. Each instance of ### substring in path is replaced with
first 3 characters of source filename.
Convert all SGD files under src in 8 threads and store them in directories
under dst designated by filename prefix, using palette example.pal and
writing full and cropped image of each selection set:
find /path/to/src -type f -name *.zgd | xargs -P 8 -n 100 ./sgd2png -cf -p example.pal -o /path/to/dst/###
Palette file must contain 8 or 16 colors in hexadecimal RR GG BB format, one
color per line. First 8 colors are regular colors, last 8 are selection colors.
If palette file has 8 colors, selection colors are obtained from the first 8 by
zeroing the blue component.
By default, images are output with custom palette fixed in source code. To get original colors, replace it with actual SGD palette (not included here).
