ScrollStep

An enum that provides the possible positions defined by a ScrollStep

• home: The starting, default position of the label
• away: The calculated position that results in the entirety of the label scrolling past.
• partial(CGFloat): A fractional value, specified by the associated CGFloat value, between the home and away positions (must be between 0.0 and 1.0).

The away position depends on the MarqueeLabel type value.

• For left, leftRight, right, and rightLeft types, the away position means the trailing edge of the label is visible. For leftRight and rightLeft default types, the scroll animation reverses direction after reaching this point and returns to the home position.
• For continuous and continuousReverse types, the away position is the location such that if the scroll is completed at this point (i.e. the animation is removed), there will be no visible change in the label appearance.

The desired time between this step and the previous ScrollStep in a sequence.

The animation curve to utilize between the previous ScrollStep in a sequence and this step.

The position of the label for this scroll step.

The option set defining the edge fade state for this scroll step.

Possible options include .leading and .trailing, corresponding to the leading edge of the label scrolling (i.e. the direction of scroll) and trailing edge of the label.
