Rasterization

This crate provides iterators and adapters for generating sequential coordinates for various shapes of a circle or its parts using Bresenham's algorithm.

Visual examples of different shapes:



Examples

Here's how to use the crate:

use rasterization::{Rasterization, SemicircleFilled, DirectionGradient::Bottom};

let radius = 128_usize;
let iter = SemicircleFilled::<i32>::new(radius)
    .circle()
    .offset(radius as i32, radius as i32);

let iter = SemicircleFilled::<i32>::new(radius)
    .circle_long(-128, 0)
    .offset((radius * 2) as i32, radius as i32);

let iter = SemicircleFilled::<i32>::new(radius)
    .semicircle_top()
    .offset(radius as i32, radius as i32);

let iter = SemicircleFilled::<i32>::new(radius)
    .semicircle_bottom()
    .offset(radius as i32, radius as i32);

let iter = SemicircleFilled::<i32>::new(radius)
    .circle()
    .offset(radius as i32, radius as i32)
    .gradient(radius as i32, radius * 2, Bottom(colorous::BROWN_GREEN));
