AI-generated Key Takeaways

• The WritingArea class defines the properties of the on-screen area where users can draw ink.

• It includes properties for width and height, measured in the same units as StrokePoint.

• A WritingArea object is initialized with specific width and height values, using consistent units with Ink and related objects.

• The default initializer is unavailable; developers should use init(width:height:) to create a WritingArea instance.
