Struct footile::Plotter

pub struct Plotter { /* private fields */ }

Plotter for 2D vector paths.

This is a software vector rasterizer featuring high quality anti-aliasing. Paths can be created using PathBuilder. The plotter contains a Mask of the current plot, which is affected by fill and stroke calls. Using the color_over method will cause a Raster to be created with the same height and width as the mask.

Example

use footile::{PathBuilder, Plotter};
let path = PathBuilder::new().pen_width(3f32)
                       .move_to(50f32, 34f32)
                       .cubic_to(4f32, 16f32, 16f32, 28f32, 0f32, 32f32)
                       .cubic_to(-16f32, -4f32, -4f32, -16f32, 0f32, -32f32)
                       .close().build();
let mut p = Plotter::new(100, 100);
p.stroke(&path);
