![]() (original_width, original_height) = image.sizeĪspect_ratio = original_height/float(original_width) """Resizes an image preserving the aspect ratio. The default char mapping and resolution doesn't render good ASCII arts for every image size and so you should try modifying the char mapping and image size to the one that best represents the given image.įrom PIL import Image ASCII_CHARS = [ '#', '?', '%', '.', 'S', ' ', '.', '*', ':', ',', scale_image(image, new_width=100): The code given below is almost self explanatory. We use the PIL library to play with the images. The point is to assign a group of pixels with slightly varying intensity the same ASCII char. We divide the whole range of 0-255 into 11 smaller ranges of 25 pixels each and then assign each pixel a character according to the range it falls in. ![]() A pixel withĪ value of 0 is assumed to be black and the one with 255 is assumed to be white. In a grayscale image, there are 256 shades of gray, or in other words, each pixel carries only the intensity information which is represented by an 8 bit value. The scaled version is then converted to a grayscale image. We scale a given image to a standard resolution that suitably represents the ASCII version of a given image. One of the utility I learnt at the workshop was an image to ASCII art generator. I was amazed at how easy it was to write simple solutions to complex problems in Python. This workshop that I met "Python" and fell in love with her at first sight. *The pattern is expected to be given in ffmpeg format.A few years ago, when I was in college, I attended a workshop organized by FOSSEE and it was in Java public void breakVideoIntoImages(File inputVideo, int fps, File outputDir, String pattern) Breaks a video into multiple images, following a certain pattern to save them in a certain folder. *The pattern is expected to be given in ffmpeg format. Java public void generateGIF(File inputDir, String pattern, File outputGIF) Renders a GIF, based on the ascii version of all files that follow the given pattern inside a certain folder. Java public void generateImage(File inputImage, File outputImage) Renders the ascii version of an image. Java public String generateString(File inputImage) Returns a string that contains the ASCII version of the given image. The API is exposed in the class DASCIIvinci. ![]() This is done when constructing a class, like this:įile pythonScript = new File("C:\path\To\script.py") įile ffmpegExecutable = File("C:\path\To\wkhtmltoimage.exe") įile wkhtmltoimageExecutable = new File("C:\path\To\ffmpeg.exe") DASCIIvinci dasciivinci = new DASCIIvinci(pythonScript, ffmpegExecutable, wkhtmltoimageExecutable) The install location of this dependencies must be announced to the library. Wkhtmltoimage: Used to generate images based on HTML. The code receives only the image path and returns both a txt file containing the converted image and the text in the terminal itself.Īn exemple of ASCII art is (we recommend copying and pasting the following characters into a text editor): Alt textĪnd to assemble the gifs when using a sequence of images we created this java library which can be used by other programs to generate ASCII-art.Ī python script (thus python): Used to process the input image and generate ASCII-art.įFmpeg: Used to break videos into multiple images and joining multiple images into a GIF. One to make the image grayscale Another to convert each pixel to an ASCII characterĪnd also a main function where the inputs and function calls are. Our development consisted of creating functions that make each part of the step To build the code that converts an image into ASCII text, it uses the PIL library that reads the image Convert each gray pixel to an ASCII character that has the same intensity as the pixel.Resize the image to the custom size keeping an aspect ratio.When converting an image to ASCII text it is necessary to follow a few steps: For development uses a python language to develop code that reads and converts the image to ASCII The project was developed for the ASCII art.
