To let every pixel influence the resulting ASCII char, we loop them and calculate the brightness of the amount of the current 10 x 5 block. How to generate the ASCII art from our image.

Loop through the image's pixels (because we don't want one ASCII character per pixel, we take one per 10 x 5).

Grayscale the bitmap using a Graphics object.

Load the Image stream to a bitmap object.

These are the steps the program/library performs: I found this CodeProject article written by Daniel Fisher containing a simple C# implementation of a image to ASCII art conversion algorithm.

For example, a "slash" ( /) would be a better choice than a "backward slash" ( \) for a pixel block that appears to have a bottom-left-to-upper-right contrast feature. The program can do two things: Convert pictures into ASCII-Art Convert text into ASCII-Art I splitted the task into several steps: Convert text to image Read image and its height and width Saving data of each pixel Convert pixel data into ASCII-char Printing Code Control. A more sophisticated version will also take the actual shapes of the characters into account when breaking ties among candidates for a pixel block. You probably won’t recognize me, but that’s me in ASCII in the image below.

It is a command line based tool written in Go and it prints the ASCII version of the image supplied to it. That's the simplest form of the exercise. Ascii Image Converter As the name suggests, Ascii Image Converter is a tool that converts an image into ASCII art. (Using the pixel blocks just mentioned, a 240w-x-320h image would become 64 lines of 60 characters.)Ĭompute the average gray-scale value of each pixel block.įor each pixel block, select a character whose gray-scale value (from step 1) is a good approximation of the pixel block average (from step 3). Each such block will become one character in the output. a rectangle 4 pixels wide and 5 pixels high).

The effect will vary, depending on the font and spacing actually used.īased on the proportions of the chosen font, group the input image into rectangular pixel blocks with constant width and height (e.g. Creat ASCII art from an image using the simple, fast, free and online tool for converting ASCII from images. #.::::::W:, big-picture-level concept is simple:Įach printable character can be assigned an approximate gray-scale value the "at" sign obviously is visually darker than the "plus" sign +, for example.

How does such an image conversion algorithm work? There are some nice free "image to ASCII art" conversion sites like this one:
