Struct View 

pub struct View {
    pub width: f64,
    pub height: f64,
    pub zoom: f64,
    pub origin: (f64, f64),
}

A view of a drawing: width × height device pixels showing the drawing scaled by zoom, its top-left at origin, a whole device pixel.

Fields

width: f64

height: f64

zoom: f64

origin: (f64, f64)

Implementations

impl View

pub fn tiles(&self, area: KRect, level: Level) -> Vec<(u32, u32)>

The tiles at level the view shows, as columns and rows of the drawing area × level, nearest the view’s middle first.

pub fn place(&self, area: KRect, key: &Key) -> Option<KRect>

Where a tile at any level lands in the view, in device pixels — (x0, y0, x1, y1) — or None when the view doesn’t show it.
