[−][src]Crate raqote

A pure Rust 2D Graphics Library.

Raqote aims to be a small, simple, fast software 2D graphics library with roughly the same capabilities as the cairo image backend.

Current functionality

  • path filling
  • stroking
  • dashing
  • image, solid, and gradient fills
  • rectangular and path clipping
  • blend modes

Planned functionality

  • layers
  • extended blend modes
  • two circle radial gradients
  • perspective image drawing
  • shadows?

Example:

use raqote::*;

let mut dt = DrawTarget::new(400, 400);

let mut pb = PathBuilder::new();
pb.move_to(100., 10.);
pb.cubic_to(150., 40., 175., 0., 200., 10.);
pb.quad_to(120., 100., 80., 200.);
pb.quad_to(150., 180., 300., 300.);
pb.close();
let path = pb.finish();

let gradient = Source::RadialGradient(
    Gradient {
        stops: vec![
            GradientStop {
                position: 0.2,
                color: 0xff00ff00,
            },
            GradientStop {
                position: 0.8,
                color: 0xffffffff,
            },
            GradientStop {
                position: 1.,
                color: 0xffff00ff,
            },
        ],
    },
    Transform::create_translation(-150., -150.),
);
dt.fill(&path, &gradient, &DrawOptions::new());

let mut pb = PathBuilder::new();
pb.move_to(100., 100.);
pb.line_to(300., 300.);
pb.line_to(200., 300.);
let path = pb.finish();

dt.stroke(
    &path,
    &Source::Solid(SolidSource {
        r: 0x0,
        g: 0x0,
        b: 0x80,
        a: 0x80,
    }),
    &StrokeStyle {
        cap: LineCap::Round,
        join: LineJoin::Round,
        width: 10.,
        mitre_limit: 2.,
        dash_array: vec![10., 18.],
        dash_offset: 16.,
    },
    &DrawOptions::new()
);

dt.write_png("example.png");

LinearGradients have an implicit start point at 0,0 and an end point at 256,0. The transform parameter can be used to adjust them to the desired location. RadialGradients have an implict center at 0,0 and a radius of 128.
