Using Options
on IconData
reveals:
Options @ IconData
(* {Background → None, ImageSize → Automatic} *)
Great! Let's simply use them:
IconData[ "WindDirection", 315, Background -> None ]
Why are we getting an unknown option error (OptionValue)? Is something similar also observable for other built-in functions?
Note: This will also happen for ImageSize
.
I am using Version 11.3 on Windows 10 (64 Bit).
Update:
While we may argue about the above -- after all the documentation for IconData
will not show valid options --, note the following behavior:
SetOptions[ IconData, Background → Green];
IconData["WindDirection", 315]
You will note, that the options indeed have changed, but now there is no green background, while
IconData["WindDirection", 315, Background -> Green]
will show a green background albeit throwing an error message as given above.
