Think of characters like the # or the those fill the space and when repeated, they’ll provide a dense splash of contrast color: the other hand, the space character or a dot are way more “empty”, in the sense that they fill less space when repeated:ĭepending on the surface you’re painting your ASCII art on and the color of your text, the “full” characters will of course be more white or more black. This mapping requires us to define a range of ASCII characters that are more or less “full”. we map it to a corresponding ASCII character.you go through each pixel of the original image.To turn an image into its exact ASCII art equivalent, meaning we put one character for one pixel, the process is pretty straight-forward: ![]() But the more pixels you have, the larger your image is, because it contains a lot more data! ASCII art is nice in that regard because you can significantly simplify your ASCII image (and therefore the number of “pixels”) in it without worrying too much about it loosing its smoothness… since you’re limited to the size of a character anyway □ Of course, the more pixels you have, the less “blocky” and the “smoother” the result looks – this is called the resolution of your image. For example, this super-basic (and super-small) image can be represented by the integers array below: Ultimately, this means that an image is a 2D array of integers from 0 to 255.
