I’ll also be using the PIL image library to keep the code as simple and abstract as possible.░░░░░░███████ ]▄▄▄▄▄▄▄▄ Bob is building an army.

This value refers to the sum of all the pixel’s channels, divided by the sum of the maximum values the channels can have (in this case 255).įrom now on I’ll be using Python for the code examples for its simplicity and readability, but feel free to use any technology you prefer. To understand this, we must first take a look at pixel color intensity.

Now that we’ve seen how images are represented, it’s time to talk about how a pixel can be transformed into an actual ASCII character. RGBA is what we’ll be working with since it can also be used to represent a void background. The difference between the two is that the latter has an additional channel, called “alpha”, that specifies the image opacity. Among the most common color values there are the classic RGB (Red Green Blue) and RGBA (Red Green Blue Alpha). They’re usually represented as a set of channels, also referred as colors. The actual image you see is composed of pixels, the smallest addressable element of a raster image which we’re all familiar with. The former stores useful information about the image such as its format signature, whereas the latter stores the actual pixel data. All these file types have a similar structure: they’re roughly composed of an header and a data section. Pictures are usually stored in formats such as. But can you represent a more complex image with just printable ASCII characters? What an image actually isįirst of all, is important to clarify how an image is represented in computer systems. The simplest form of this art are emoticons such as :-) or :-3.

I’m sure many of you have heard of ASCII art, a graphic design technique that uses the printable ASCII character set to compose pictures. ASCII version of original image by freestocks on Unsplash
