Struct Plotter 

pub struct Plotter<P>
where
    P: Pixel<Chan = Ch8, Alpha = Premultiplied, Gamma = Linear>,
{ /* private fields */ }

Plotter for 2D vector paths.

This is a software vector rasterizer featuring anti-aliasing. The plotter contains a raster, which is drawn by fill and stroke calls.

Example

use footile::{Path2D, Plotter};
use pix::rgb::Rgba8p;
use pix::Raster;

let path = Path2D::default()
    .pen_width(3.0)
    .move_to(50.0, 34.0)
    .cubic_to(4.0, 16.0, 16.0, 28.0, 0.0, 32.0)
    .cubic_to(-16.0, -4.0, -4.0, -16.0, 0.0, -32.0)
    .close()
    .finish();
let mut p = Plotter::new(Raster::with_clear(100, 100));
p.stroke(&path, Rgba8p::new(255, 128, 0, 255));

Implementations
