Encode data into an image using LSB-Steganography, and output as a PNG file.
Usage: hii [OPTION]... [FILE] [-m MSGFILE | -t MSGTEXT] [-o OUTFILE]
hii -x [OPTION]... [FILE] [-m MSGFILE]
hii -s [OPTION]... [FILE]
Encode data into an image using LSB-Steganography, and output as a PNG image.
Input image supports JPEG, PNG, BMP, PSD, TGA, GIF, HDR, PIC, PNM format.

-m, --msgfile MSGFILE read/write msg from MSGFILE.
-t, --msgtext MSGTEXT specify msg in cli.
-x, --extract extract msg to MSGFILE.
-b, --bit N insert N bit msg per byte(subpixel), 0 < N < 8
-v, --verbose verbose mode.
-q, --quiet suppress error messages.
-s, --show-info show some info about FILE, can be combined with -x.
-O 0-9, --optimize optimize png file for size.
-h, -?, --help give this help.
-V, --version show version.
Default MSGFILE is "-" (stdin or stdout).
Examples:
# encode msg.txt into g.png, write output to g.out.png
hii g.png -m msg.txt -o g.out.png
# extract message to stdout from g.out.png
hii -x g.out.png
# show some information about g.out.png
hii -s g.out.png
# encode 'abcdefg' into g.png
