How to remove those background white dots that appear in the ascii version?

Somewhat late, but if you have sed installed you can pipe the output of asciify into sed to replace .'s with spaces:

python3 ./asciify.py ./image.png | sed 's/\./ /g'

Thanks for sharing a solution. While the way to change the actual implementation would be to replace ASCII_CHARS[-1] with a blank space character, the solution described above would be better since it's entirely user-facing.
