Struct Placement

pub struct Placement {
    pub cx: f32,
    pub cy: f32,
    pub w: f32,
    pub h: f32,
    pub rot: f32,
    pub yaw: f32,
    pub pitch: f32,
}

Where a layer lands on a canvas of (cw, ch) pixels: centre, size and rotation (degrees, clockwise). yaw/pitch (degrees) tilt the layer about the vertical/horizontal axis (camera shake) — rendered through a perspective homography with focal length ≈ canvas width; 0 = flat.

Fields

cx: f32

cy: f32

w: f32

h: f32

rot: f32

yaw: f32

pitch: f32

Implementations

impl Placement

pub fn bounds(&self) -> (f32, f32, f32, f32)

Axis-aligned bounding box (x0, y0, x1, y1) of the flat (yaw/pitch = 0) rect.

Trait Implementations

impl Clone for Placement

fn clone(&self) -> Placement

Returns a copy of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for Placement

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl PartialEq for Placement

fn eq(&self, other: &Placement) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
