Struct Rect 

pub struct Rect {
    pub x: f64,
    pub y: f64,
    pub w: f64,
    pub h: f64,
}

An axis-aligned rectangle in continuous pixel coordinates (ffcine_core::geom).

Fields

x: f64

y: f64

w: f64

h: f64

Implementations

impl Rect

pub fn frame(w: f64, h: f64) -> Self

The whole w x h frame.

pub fn aspect(&self) -> f64

pub fn fit_aspect(&self, ar: f64, pos: [f64; 2]) -> Self

The largest window of aspect ar (width / height) inside this one, placed by pos: 0 at the left/top edge, 0.5 centred, 1 at the right/bottom edge (fractions of the slack, as the prototype’s crop_x / crop_y).

pub fn zoom(&self, zoom: f64, pos: [f64; 2]) -> Self

A window 1 / zoom of this one’s size, placed by pos in the slack: the prototype’s crop=iw/z:ih/z:(iw-iw/z)*cx:(ih-ih/z)*cy. Zooms below 1 count as 1, so the window never leaves the picture.

pub fn to_mat3(&self, out_w: f64, out_h: f64) -> Mat3

The map from a pixel of a out_w x out_h image showing this window to the source pixel it samples (a Mat3 in the stabilizer’s convention: output -> source).

pub fn to_crop(&self) -> Crop
