Struct Object 

pub struct Object {
    pub kind: Kind,
    pub bx: usize,
    pub by: usize,
    pub bw: usize,
    pub bh: usize,
    pub mask: Vec<bool>,
    pub tpl: Vec<[u8; 3]>,
    pub stable: Vec<u32>,
    pub coarse: Vec<u32>,
    pub textured: bool,
    pub last: (i32, i32),
    pub flat: Option<[u8; 3]>,
}

Fields

kind: Kind

bx: usize

Bounding box in cells, relative to the layer’s cell grid.

by: usize

bw: usize

bh: usize

mask: Vec<bool>

Cells of the object inside its box.

tpl: Vec<[u8; 3]>

Template: mean appearance of each cell when it disagreed with the page.

stable: Vec<u32>

Cells whose appearance is stable (low spread when present); matching uses only these.

coarse: Vec<u32>

A thinned subset of stable for coarse searches.

textured: bool

Enough stable edges for a shifted match to be meaningful (a flat template would match any flat area).

last: (i32, i32)

Offset (cells) where the object was last found.

flat: Option<[u8; 3]>

A uniformly coloured object (a scrollbar thumb, a flat bar): its colour. Its learned mask is smeared over everywhere it travelled, so it is found per frame by colour inside its zone instead of by template.

Implementations

impl Object

pub fn area(&self) -> usize

pub fn track(&self) -> Track

The axis an elongated object may travel along (a scrollbar thumb’s track), if any.

pub fn zone(&self, cw: usize, ch: usize) -> (usize, usize, usize, usize)

Cells where this object may appear in a frame: its box, run along the long axis to the layer edge when it is elongated (a scrollbar thumb travels its whole track). (x0, x1, y0, y1), half-open, in cells.

Trait Implementations

impl Clone for Object

fn clone(&self) -> Self

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Object

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

Formats the value using the given formatter.
