Compare with:

A set of transformations that can be applied to a blob to create a variant. This class is exposed via the ActiveStorage::Blob#variant method and should rarely be used directly.

In case you do need to use this directly, it’s instantiated using a hash of transformations where the key is the command and the value is the arguments. Example:

ActiveStorage::Variation.new(resize_to_limit: [100, 100], monochrome: true, trim: true, rotate: "-90")

The options map directly to ImageProcessing commands.
