Collection of Cells

Fields

min_x: i64

Minimum x value of current cells

max_x: i64

Maximum x value of current cells

min_y: i64

Minimum y value of current cells

max_y: i64

Maximum y value of current cells

sorted_y: Vec<Vec<Cell>>

Cells sorted by y position, then x position

Implementations

impl RasterizerCell

pub fn new() -> Self

Create new Cell collection

pub fn reset(&mut self)

Clear cells

pub fn total_cells(&self) -> usize

Return total number of cells

pub fn sort_cells(&mut self)

Sort cells into sorted_y cells

Cells are distributed into y bins, then sorted by x value

pub fn scanline_num_cells(&self, y: i64) -> usize

Return number of cells in a specific y row

pub fn scanline_cells(&self, y: i64) -> &[Cell]

Returns the cells of a specific y row

pub fn line(&mut self, x1: i64, y1: i64, x2: i64, y2: i64)

Draw a line from (x1,y1) to (x2,y2)

Cells are added to the cells collection with cover and area values

Input coordinates are at subpixel scale

Trait Implementations

impl Debug for RasterizerCell

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

Formats the value using the given formatter.

impl Default for RasterizerCell

fn default() -> RasterizerCell

Returns the “default value” for a type.
