How To Install zimg on CentOS 8

zimg is Scaling, color space conversion, and dithering library

Introduction

In this tutorial we learn how to install zimg on CentOS 8.

What is `zimg`

The “z” library implements the commonly required image processing basics of scaling, color space conversion, and depth conversion. A simple API enables conversion between any supported formats to operate with minimal knowledge from the programmer. All library routines were designed from the ground-up with correctness, flexibility, and thread-safety as first priorities. Allocation, buffering, and I/O are cleanly separated from processing, allowing the programmer to adapt “z” to many scenarios.

We can use yum or dnf to install zimg on CentOS 8. In this tutorial we discuss both methods but you only need to choose one of method to install zimg.
