DrawBounds

tilo_app::scene_parts

Struct DrawBounds 

pub struct DrawBounds { /* private fields */ }
Expand description

Device-space bounds of everything a scene paints, for a caller that must know what lies over a region without rasterising the scene. Keep one: it retains glyph outlines across calls.

Implementations§

§

impl DrawBounds

pub fn of(&mut self, encoding: &Encoding) -> Option<Vec<Rect>>

Every pixel encoding can paint, as device-space rectangles: each draw’s path (stroke reach included) or glyph outlines under its transform, and the clip of every layer that blends other than by source over. A layer’s clip is not applied, so the bounds hold whatever it clips. None when some draw cannot be bounded.
