Finally, append different ASCII characters based for the current block on the calculated amount.īTW: In the comments to the article I found this cool AJAX implementation: Gaia Ajax ASCII Art Generator:.
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.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.

A more sophisticated version will also take the actual shapes of the characters into account when breaking ties among candidates for a pixel block. Apple-touch-icon generator Browser language Favicon generator Image to data-URI Lipsum generator Obfuscate Email address Request headers String manipulation User-Agent string CSS3. That's the simplest form of the exercise. (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. #.::::::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?

Keep in mind that, the shorter the width, the less overall visibility and clarity you get of the image however, it can turn out to be a bit of a balancing act.There are some nice free "image to ASCII art" conversion sites like this one: You might need to adjust the “output width in characters” to ensure the text editor you’re entering into has enough width. However, you will notice characters combine together to provide the outline (including the shading) of the image provided. It simply translates your image into a range of dedicated characters that can be then copied and pasted to an open text editor.
