[−][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
- layers
- repeat modes for images
- global alpha
Planned functionality
- perspective image drawing
- shadows?
Notable users
- resvg supports using raqote as a backend.
- Servo can use raqote as a canvas backend.
- orbtk uses raqote.
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::new_radial_gradient( Gradient { stops: vec![ GradientStop { position: 0.2, color: Color::new(0xff, 0, 0xff, 0), }, GradientStop { position: 0.8, color: Color::new(0xff, 0xff, 0xff, 0xff), }, GradientStop { position: 1., color: Color::new(0xff, 0xff, 0, 0xff), }, ], }, Point::new(150., 150.), 128., Spread::Pad, ); 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., miter_limit: 2., dash_array: vec![10., 18.], dash_offset: 16., }, &DrawOptions::new() ); dt.write_png("example.png");

Source | 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. |
