How to control image resolution (size) when using TakePhotoFromCameraAction (FMX.MediaLibrary.Actions) in FireMonkey?

On both Android & iOS, I am successfully using TTakePhotoFromCameraAction in FMX to save photos taken by the user into a TImage.

When using TTakePhotoFromCameraAction, can I control the resolution (ultimately the size in bytes) of the photo that's taken? If so, how?

What is the best way to "post process" the resultant TImage to achieve a reduction in size? I ask this because I may need this functionality anyway if I am to begin using TTakePhotoFromLibraryAction to allow a user to choose an existing photo from their gallery.

I do need a solution that will work with both Android & iOS, please.

I am currently using Delphi 10.4.2 Sydney

TTakePhotoFromCameraAction has MaxWidth and MaxHeight properties.

If you use IFMXCameraService.TakePhoto() instead, it has an overload that takes a TParamsPhotoQuery parameter, which has a RequiredResolution field.

TTakePhotoFromLibraryAction also has MaxWidth and MaxHeight properties.

And IFMXTakenImageService.TakeImageFromLibrary() has an overload that has an ARequiredResolution parameter, and an overload that takes a TParamsPhotoQuery parameter.
