Problem

I am trying to implement some vector drawing with ratatui, but I face problem. The ratatui::widgets::canvas::Line method can't draw a line if one of the points is outside the window. In theory I can calculate the intersection and draw a shorter line, but I need to know the resolution from Shape. get_point doesn't help because it just returns none if the point is outside. Also context is a private field and I don't have access to the required fields.

Solution

I see few solutions:

• Public access to context in Painter.
• Additional methods like resolution and context bounds
• New property for widgets that need context

Alternatives

I can use context before calling draw or draw without shape implementation, but it doesn't look consistent.

Additional context

I can try to implement some of the solution, but I am not sure which way is better
