This chapter is all about introducing the JuliaImages collection. JuliaImages is a collection of different packages that are used for image processing. We will look into the Images.jl and ImagesMetadata.jl packages, load and preview images from various sources, read metadata, resize and scale images, create thumbnails, and save them back to disk in a different format.
In this chapter, we will cover the following topics:
- Setting up Julia
