Item Frame-Inator

Minecraft data pack to give control over item frame properties: Fixed, Invisibile, and ItemRotation.

Fixed: 1, or 0 (true/false) - If true: the item frame does not drop when it has no support block, it can not be moved by pistons, and it won't take damage (except from creative players). An item cannot be placed in or removed from a fixed item frame. The item in a fixed item frame (if any) can not be rotated.
Invisible: 1, or 0 (true/false) - Whether the item frame (background) is invisible. An item or map inside an invisible item frame is still visible.
ItemRotation: The current angle or rotation of the item, as a multiple of 45 degrees, going clockwise. 0 means the item is upright, 1 means the item is turned 45 degrees clockwise from the upright orientation.[more information needed] This value can only ever be between 0 and 7, just like its redstone output when measured with a comparator.

/trigger itemframeinator_reset - Resets Invisible and Fixed properties (i.e. makes the item frame visibile and unlocked)
/trigger itemframeinator_invisible - Toggles Invisible property
/trigger itemframeinator_fixed - Toggles Fixed property
/trigger itemframeinator_rotation set # - Sets ItemRotation to a number between 0 and 7
/trigger itemframeinator_reset_rotation - Resets ItemRotation to 0 (default orientation)
