Display a random cow with a random facial expression and wrap long lines of fortune text:.( (computers) % A language that doesn't )Ĭomplex commands can be chained to produce detailed ASCII art such as this Futurama example. Random cow with fortune $ fortune -c | cowthink -f $(find /usr/share/cows -type f | shuf -n 1) The easiest way create a custom cow file is to use an existing one as a template. These files can be edited to the user's liking custom images can also be created from scratch or found on the net. cow text files located in /usr/share/cows, and all themes can be listed with the cowsay -l. emacs - Artist-mode is a built-in package in GNU Emacs that allows you to create simple drawings and diagrams using the Emacs text editor.sl - A steam locomotive runs across your terminal when you type sl as you meant to type ls.tty-clock - A digital clock in ncurses.TOIlet - Free replacement for the FIGlet utility.nyancat - Renders nyancat in your terminal.neo-matrix - Simulates the digital rain from "The Matrix".jp2a - A small utility for converting JPG and PNG images to ASCII.FIGlet - A program for making large letters out of ordinary text.cmatrix - Animation that plays in terminal based on the text from "The Matrix".catimg - Print images in a terminal with 256 colors support.cbonsai - A bonsai tree generator, written in C using ncurses. boxes - Text mode box and comment drawing filter.bash-pipes - An animated pipes terminal screensaver.Banner - Print large banners to ASCII terminals.Asciiquarium - An aquarium/sea animation in ASCII art.ascii-rain - Comfy rain for your console written in C with Ncurses.# define cimg_display 0 // no need to show imageĬImg gray_img (color_img.width(), color_img.height(), 1, 1, 0) Convert the pixel value to a number res not bigger than l.Define a string S which contains different ASCII code.(And its length l is better to be short).Crop the image to the desired size (usually smaller than its original size).If the image is not gray, convert it to gray image.So the conversion steps become very simple: In my project we need to deal with a jpg image, so we need to download ImageMagick in our computer to convert the jpg image into bmp image Conversion Principleīecause we will use ASCII code to represent the image, and the ASCII code only has one color, we only need to process a gray image. NOTE: The CImg library can only deal with bmp file. To use this repo, we just need to put the header file CImg.h into our own project folder and include it in the program. So, I tried to find a light-weight image processing processing library called CImg. They are not familiar with the image processing and it’s to hard for them to install OpenCV in their computer. Since this project is written for others. To process a image, the easiest way is using a open source library.
