How To Install jpegpixi on Ubuntu 22.04
Introduction

What is jpegpixi
jpegpixi is:
jpegpixi is short for “JPEG pixel interpolator”. It is a command-line utility which interpolates pixels in JFIF images (commonly referred to as “JPEG images”). This is useful to correct images from a digital camera with CCD defects.
jpegpixi tries to preserve the quality of the JFIF image as much as possible. Most graphics programs decode JFIF images when they are loaded, and re-encode them when they are saved, which results in an overall loss of quality. jpegpixi, on the other hand, does not decode and re-encode the image, but manipulates the encoded image data. In doing so, it also preserves EXIF metadata.
