*** Sixel ***

I never knew I could see a picture in a
command-line interface under a terminal
until I was told that. Thanks to Helenah,
I  got  to know  about  Sixel.  Sixel is
actually a  bitmap graphics  format  for
displaying a picture.
Linux has a bunch of terminals to be used:
xterm, mlterm and others. Windows has the
Cygwin64 terminal.
Any  picture can  be converted into  sixel
format, and a terminal decodes the complete
sixel image to the screen.
There is a nice project called "ImageMagick"
(http://imagemagick.org), that has versions
for  Linux, macOS and Windows.  ImageMagick
has a legacy utility called "convert" which
does  what we essentially need to.  Like, if
running, for exmaple, as follows:

$ convert ./some_image.png ./some_image.six

we will receive a complete sixel image.
To display it under a console, we should type
the following:

$ cat ./some_image.six

It works well  on every  platform with having
Sixel supported.
