I have done the converting image into Ansi art.
The problem is a pixel on terminal usually equal to 2 pixel on the picture.
So this function basically treat a pixel on terminal as 2 pixel on the picture, then using the foreground and background coloring to workaround the 2-pixel problem.
In theory, it should work now, but the size of the object is just too big so I’m implement NumPy to solve this problem
