This package provides support for loading and saving images using native libraries on macOS. This package was split off from Images.jl to make image I/O more modular.

Add the package with

Pkg.add("QuartzImageIO")

QuartzImageIO will be used as needed if you've said

using FileIO

in your session or module. You should not generally say using QuartzImageIO. See FileIO for further details.

It's worth pointing out that packages such as Images load FileIO.

If QuartzImageIO does not provide the functionality you need, an alternative is ImageMagick. You can have both packages installed, and FileIO will manage their interaction.
