> When embedding JPEGs into a container file format Could you provide an example how to use `no_default_app_segments` to embed in container and which containers this could be?
An idea: use the same callback for generating frames: pass current `im` object (which could be an image without bitmap in memory) and check if complete image is returned.
In general, yes. Depending on current code flow, it could be like this, or require some informations about the frames (like size and mode).

Having iterators support you can track progress without any callbacks.
I personally don't have preferences what to store in unused bytes. Also I guess performance impact should be near zero/
Currently Pillow doesn't coerce images to required mode for most operations. This is not unique to `ImageEnhance.Contrast`. The application should resolve this on it's own.

It's not just not comparable, it in totally wrong state. I believe we should prevent from creating objects like this, but this requires further discussion.
