The other two variables, `image_base64` and `binary_image`, are an image encoded in Base64, and then converted to bytes, to then pass it to `io.BytesIO`.

Only so that it can live in the same file for this example and you can copy it and run it as is. 🥚

Then, in **FastAPI**, you could use a Python class as a dependency.

What FastAPI actually checks is that it is a "callable" (function, class or anything else) and the parameters defined.

If you pass a "callable" as a dependency in **FastAPI**, it will analyze the parameters for that "callable", and process them in the same way as the parameters for a *path operation function*. Including sub-dependencies.
