Thank you all!
@Butters, @Magnetron
My aim is not at all to tinker with garmin propietary protected maps. I am happy with the lifetime updates of CN I paid for, and I do not plan either to tinker with those IMGs.
My target is to use in my garmin those osm free maps in IMG mapset format, such as the ones provided in [Only registered and activated users can see links. ]
Besides eventually for my GPSrs, the most interesting use of the IMGs for me is to plan trips (for what I use user oriented open software that is able to use IMGs - other formats need more expertise). Editing maps (beyond chopping not needed areas and adjusting zoom) is not my interest, just a hassle in order to allow me the planning: for practical reasons I wish to have smaller size files just of the areas of interest for me. Lets say, for example, I wish just Ireland but not UK in the same file. So I wish to remove UK from the file. Or just the Loira river area and not full France. Sydney but not Adelaida. Algonquin Park but not full Ontario. Benin but not full Africa. Yosemite Park but not full California. You name it.
Tools go (MapEdit cannot load full size France IMG), go faster (CPU, RAM reasons), less Disk access and lower use of storage...
I am really surprised to find out that no tool seems available to do what I would like. Even to build up a toolchain with command based executables performing each one step. But starts to look that garmin IMG tinkering is passé, old knowledge forgotten, no further/new tools development that use it. There is not even a x64 version of MapEdit! (with big issues of RAM limitations) - seems there is no demand for Konstantin to take the effort. It seems a miracle that he keeps it updated and removing issues and adding some features.
@Butters
Tinkering with garmin maps (even purchased ones) is illegal in most countries, but others not (although usually restricted to own non-commercial fair use). Whatever is the case, I am not interested in that, but note that although illegal it can be done; same applies to GPSrs firmware.
GMaptool is the a) path that I indicated and the less un-efficient.
@JmaCWQ
So, can zoom levels be adjusted with a different TYP file?
TIA again,
