Save GannGrid Object Data for later retrieval.

I need to be able to switch templates and then recall/reapply object configuration.

First goal is GannGrid Objects - imagine they are built on chart already and will be named like that too.. with name like "GannGridxx*" ..where xx might be anything.

I would really appreciate if you could provide two scripts, one for save and one for load, both silent.

This method and library I would like to see used:

https://www.mql5.com/en/docs/standardlibrary/chart_object_classes/obj_gann/cchartobjectganngrid

... see the Save and Load methods, and how they say, saves object parameters to a file..?

Surely someone done this before with those methods?

Also, I desperately need a way to query for if the background is black, hopefully that is child's play for someone here.

Appreciate the help and your consideration here.

Please let me know your approach to this if you have one.. 

thanks!

Simon
