Struct Canvas2D

pub struct Canvas2D {
    pub size: Vec2,
    pub screen: Vec2,
    pub scale: f32,
    pub offset: Vec2,
}

Fits a Y-down logical canvas into a logical-pixel screen, centered with letterboxing. Uses camera zoom rather than a raw GPU viewport, so high-DPI screens behave identically.

Fields

size: Vec2

screen: Vec2

scale: f32

offset: Vec2
