Introduction
In this tutorial we learn how to install caca-utils on CentOS 8.
What is caca-utils
This package contains utilities and demonstration programs for libcaca, the Colour AsCii Art library. cacaview is a simple image viewer for the terminal. It opens most image formats such as JPEG, PNG, GIF etc. and renders them on the terminal using ASCII art. The user can zoom and scroll the image, set the dithering method or enable anti-aliasing. cacaball is a tiny graphic program that renders animated ASCII metaballs on the screen, cacafire is a port of AALib’s aafire and displays burning ASCII art flames, and cacademo is a simple application that shows the libcaca rendering features such as line and ellipses drawing, triangle filling and sprite blitting.
